  1.      Introduction
  
     This specification defines the naming syntax, object classes,
     attributes, matching filters, and query processing rules for
     storing and locating IPv6 address blocks in the FIRS service.
     Refer to [FIRS-ARCH] for information on the FIRS architecture and
     [FIRS-CORE] for the schema definitions and rules which govern the
     FIRS service as a whole.
  
     Note that reverse-lookup DNS domains for IPv6 address blocks are
     managed as DNS domain entries in [FIRS-DNS]. These are entirely
     different network resources, and should not be confused with IPv6
     address block entries.
  
     The definitions in this specification are intended to be used with
     FIRS. Their usage outside of FIRS is not prohibited, but any such
     usage is beyond this specification's scope of authority.
  
  2.      Prerequisites and Terminology
  
     The complete set of specifications in the FIRS collection
     cumulative define a structured and distributed information service
     using LDAPv3 for the data-formatting and transport functions. This
     specification should be read in the context of that set, which
     currently includes [FIRS-ARCH], [FIRS-CORE], [FIRS-DNS],
     [FIRS-DNSRR], [FIRS-CONTCT], [FIRS-ASN] and [FIRS-IPV4].

     The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL
     NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL"
     in this document are to be interpreted as described in RFC 2119.
  
  3.      Naming Syntax
  
     The naming syntax for IPv6 address blocks in FIRS MUST follow the
     form of "cn=<inetIpv6NetworkSyntax>,cn=inetResources,<partition>",
     where <inetIpv6NetworkSyntaxf> is the IPv6 address block resource,
     and where <partition> is a sequence of domainComponent relative
     distinguished names which identifies the scope of authority for
     the selected directory partition.
  
     The inetIpv6NetworkSyntax rules use the uncompressed, 32-nibble
     notation, terminated with a subnet "prefix". The network address
     consists of eight sub-components, each of which are separated by a
     colon character, and which each consist of four hexadecimal values
     that represent one nibble. The entire sequence is followed by a
     "/" character and a three-digit decimal "prefix" value.
  
     Entries which use the inetIpv6NetworkSyntax MUST use the starting
     address from a range of inclusive addresses, and MUST use CIDR
     prefix notation. In this manner, it is possible to create an
     inetIpv6Network entry for a range of addresses of any size
     (including a single host).
  
     Each of the 16-bit colon-separated values MUST be written in the
     uncompressed form. Nibbles with a value of zero MUST be
     represented by the hexadecimal sequence of "0000".
  
     If an input string does not match this syntax, a FIRS-aware
     application MAY attempt to manipulate the input string to form a
     valid value. For example, if a user enters a zero-compressed IPv6
     address such as "3ffe:ffff::", the application MAY convert the
     input value to "3ffe:ffff:0000:0000:0000:0000:0000:0000/32" in
     order to form a valid inetIpv6NetworkSyntax form.

  Internet Draft    draft-ietf-crisp-firs-ipv6-03.txt      August 2003
  
  
  
     An augmented BNF for this syntax is as follows:
  
          inetIpv6NetworkSyntax = inetIpv6Octet ":" inetIpv6Octet ":"
            inetIpv6Octet ":" inetIpv6Octet ":" inetIpv6Octet ":"
            inetIpv6Octet ":" inetIpv6Octet ":" inetIpv6Octet "/"
            inetIpv6Prefix
  
          inetIpv6Octet = 4*4nibblePart
  
          nibblePart = hexadecimal digit between "0" and "F" inclusive
  
          inetIpv6Prefix = decimal value between "1" and "128"
            inclusive, with the non-affective leading zeroes removed
  
     The inetIpv6NetworkSyntax syntax is as follows:
  
          inetIpv6NetworkSyntax
          ( 1.3.6.1.4.1.7161.1.6.0
            NAME 'inetIpv6NetworkSyntax'
            DESC 'An IPv6 address and prefix.' )
  
     For example, an IPv6 network with a range of addresses between
     "3ffe:ffff::" and "3ffe:ffff:ffff:ffff:ffff:ffff:ffff:ffff" would
     be written as "cn=3ffe:ffff:0000:0000:0000:0000:0000:0000/32".
     Similarly, a host address of "3ffe:ffff::1:2:3:4" would be written
     as "cn=3ffe:ffff:0000:0000:0001:0002:0003:0004/128".
  
     Note that the entry name of
     "cn=0000:0000:0000:0000:0000:0000:0000:0000/0" encompasses the
     entire IPv6 address space.
  
     Note that the use of "/" is illegal as data in URLs, and MUST be
     escaped before it is stored in a URL as data.
  
  4.      Object Classes and Attributes
  
     IPv6 address block entries in FIRS MUST use the inetIpv6Network
     object class, in addition to the mandatory object classes defined
     in [FIRS-CORE]. IPv6 address block entries MUST be treated as
     containers capable of holding subordinate entries.
  
     If an entry exists as a referral source, the entry MUST be defined
     with the referral object class, in addition to the other object
     classes defined above. Referral sources MUST NOT contain

     subordinate entries. Refer to section 3.5 of [FIRS-CORE] for more
     information on referral entries in FIRS.
  
     The inetIpv6Network object class is a structural object class
     which is subordinate to the inetResources object class. The
     inetIpv6Network object class has no mandatory attributes, although
     it does have several optional attributes. The inetIpv6Network
     object class also inherits the attributes defined in the
     inetResources object class, including the "cn" naming attribute.
  
     The schema definition for the inetIpv6Network object class is as
     follows:
  
          inetIpv6Network
          ( 1.3.6.1.4.1.7161.1.6.1

            NOTE: In an effort to facilitate internationalization and
            programmatic processing, the current status of a delegation
            is identified by a 16-bit integer. The values and status
            mapping is as follows:
  
                 0   Reserved delegation (permanently inactive)
                 1   Assigned and active (normal state)
                 2   Assigned but not yet active (new delegation)
                 3   Assigned but on hold (disputed)
                 4   Assignment revoked (database purge pending)
  
            Additional values are reserved for future use, and are to
            be administered by IANA.
  
            Note that there is no status code for "unassigned";
            unassigned entries SHOULD NOT exist, and SHOULD NOT be
            returned as answers.

            NOTE: The inetIpv6Registrar attribute uses a URL to
            indicate the registrar who delegated the address block. The
            attribute structure is identical to the labeledURI
            attribute, as defined in [RFC2798], including the URL and
            textual comments. The data can refer to any valid URL.

  5.      Query Processing Rules
  
     Queries for IPv6 address blocks have several special requirements,
     as discussed in the following sections.
  
     Refer to [FIRS-CORE] for general information about FIRS queries.
  
  5.1.    Query Pre-Processing
  
     FIRS clients MUST use the targeted bootstrap model by default for
     IPv6 address block queries, using the "ip6.arpa" zone as the seed
     domain for the initial query.
  
  Hall                   I-D Expires: March 2004              [page 8]


  Internet Draft    draft-ietf-crisp-firs-ipv6-03.txt      August 2003
  
  
  
     FIRS clients MAY use the top-down or bottom-up bootstrap models
     for queries if necessary or desirable. However, it is not likely
     that entries will be found for all IPv6 address block resources
     using these models. As such, the targeted bootstrap model will be
     the most useful in most cases, and MUST be used by default.
  
     When the bottom-up bootstrap model is used, the authoritative
     partition for an IPv6 address block is determined by mapping the
     normalized input to an associated reverse-lookup DNS domain name
     (using the process as defined in RFC 1886 [RFC1886], as amended by
     RFC 3152 [RFC3152]), and then mapping the resulting DNS domain
     name to a sequence of domainComponent labels. The subnet prefix
     sequence MUST be stripped from the input address block as part of
     this mapping process (note that these rules only apply to the
     mapping process by which an authoritative partition is
     constructed, and does not apply to the process by which the entry-
     specific relative distinguished name is constructed). Due to the
     128-bit addresses and the rules defined in [RFC1886], a fully-
     formed IPv6 reverse-lookup domain name will have 34 labels, which
     result in very large distinguished names.
  
     For example, an IPv6 address of
     "3ffe:ffff:0000:0000:0000:0000:0000:0000/32" would be mapped to
     the reverse-lookup DNS domain name of
     "0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.f.f.f.f.e.f.f.3.
     ip6.arpa." which would in turn be mapped to "dc=0,dc=0,dc=0,dc=0,
     dc=0,dc=0,dc=0,dc=0,dc=0,dc=0,dc=0,dc=0,dc=0,dc=0,dc=0,dc=0,dc=0,
     dc=0,dc=0,dc=0,dc=0,dc=0,dc=0,dc=0,dc=f,dc=f,dc=f,dc=f,dc=e,dc=f,
     dc=f,dc=3,dc=ip6,dc=arpa", which would then be used as the
     authoritative partition for the bottom-up bootstrap process.
  
  5.2.    LDAP Matching
  
     If the server advertises the inetIpv6Network object class and
     inetIpv6NetworkMatch matching filter in the inetResourcesControl
     server control, FIRS clients MUST use the inetIpv6NetworkMatch
     matching filter in LDAP searches for IPv6 network entries.
  
     The inetIpv6NetworkMatch filter provides an identifier and search
     string format which collectively inform a queried server that a
     specific IPv6 address should be searched for, and that any
     matching inetIpv6network object class entries should be returned.

  Internet Draft    draft-ietf-crisp-firs-ipv6-03.txt      August 2003
  
  
  
     The inetIpv6NetworkMatch matching filter is defined as follows:
  
          inetIpv6NetworkMatch
          ( 1.3.6.1.4.1.7161.1.6.0.1
            NAME 'inetIpv6NetworkMatch'
            SYNTAX 1.3.6.1.4.1.7161.1.6.0 )
  
     Clients MUST ensure that the query input is normalized according
     to the rules specified in section 3 before the input is used as
     the assertion value to the resulting LDAP query.
  
     A FIRS server MUST compare the assertion value against the
     distinguished name of all entries within and beneath the container
     of the partition specified in the search base. Any entry in that
     hierarchy with an object class of inetIpv4Network and a
     distinguished name that is clearly superior to the IPv6 address
     provided in the assertion value MUST be returned. Entries which do
     not have an object class of inetIpv6Network MUST NOT be returned.
     Entries which are not clearly superior to the queried address MUST
     NOT be returned.
  
     Note that "superiority" means that the address ranges specified in
     the entry names clearly encompass the address range specified in
     the assertion value. This can be reverse-computed by repeatedly
     shrinking the prefix size of the address in the assertion value,
     and using the resulting network/prefix pair as a matching value.
  
     An example of this matching logic for IPv4 addresses is shown in
     section 5.2 of [FIRS-IPV4].
  
     Note that the entry name of
     "cn=0000:0000:0000:0000:0000:0000:0000:0000/0" encompasses the
     entire IPv6 address space. When used in conjunction with
     referrals, this entry MAY be used to redirect all
     inetIpv6NetworkMatch queries to another partition for subsequent
     processing.
  
     The matching filters defined in this specification MUST be
     supported by FIRS clients and servers. FIRS servers MAY support
     additional matching filters, although FIRS clients MUST NOT expect
     any additional filters to be available.
  
     If the server does not advertise support for the
     inetIpv6NetworkMatch matching filter in the inetResourcesControl
     server control, the client MAY choose to emulate this matching

     filter through the use of locally-constructed equalityMatch
     filters. However, this process can result in incomplete answers in
     some cases, so if the server advertises support for the
     inetIpv6NetworkMatch matching filter in the inetResourcesControl
     control, the client MUST use it.
  
  5.3.    Example Query
  
     The following example assumes that the user has specified
     "3ffe:ffff:0000:0000:0000:0000:0000:0000/32" as the query value:
  
        a.  Normalize the input, which is
            "3ffe:ffff:0000:0000:0000:0000:0000:0000/32" in this case.
  
        b.  Determine the canonical authoritative partition.
  
            1.   Map the input sequence to the reverse-lookup domain
                 name, which is "0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.
                 0.0.0.0.0.0.f.f.f.f.e.f.f.3.ip6.arpa." in this case.
  
            2.   Determine the domain name which is appropriate for the
                 bootstrap model in use. In the default case of a
                 targeted query, use the label sequence of "ip6.arpa".
                 In the case of a bottom-up query, use the label
                 sequence determined in step 5.3.b.1. In the case of a
                 top-down query, set the domain name to "arpa".
  
            3.   Map the domain name to an authoritative partition,
                 which would be "dc=ip6,dc=arpa" if the default
                 bootstrap model were in use.
  
        c.  Determine the search base for the query, which will be
            "cn=inetResources,dc=ip6,dc=arpa" if the defaults are used.
  
        d.  Initiate a DNS lookup for the SRV resource records
            associated with "_ldap._tcp.ip6.arpa." For the purpose of
            this example, assume that this lookup succeeds, with the
            DNS response message indicating that "firs.iana.org" is the
            preferred LDAP server.
  
        e.  Submit an LDAPv3 query to the specified server, using
            "(1.3.6.1.4.1.7161.1.6.0.1:=
            3ffe:ffff:0000:0000:0000:0000:0000:0000/32)" as the
            matching filter, "cn=inetResources,dc=ip6,dc=arpa" as the
            search base, and the global query defaults defined in
            [FIRS-CORE].

        f.  Assume that no referrals are received. Display the answer
            data which has been received and exit the query.
  
  6.      Security Considerations
  
     Security considerations are discussed in [FIRS-ARCH].
  
  7.      IANA Considerations
  
     This specification uses the "dc=ip6,dc=arpa" directory partition
     by default. It is expected that authoritative LDAP partitions will
     be mapped to that zone, and that FIRS-capable LDAP servers will be
     established to service this partition, with this partition
     containing IPv6-specific entries which will provide referrals to
     the appropriate RIR partitions. It is further expected that IANA
     will oversee the creation and management of the ip6.arpa domain's
     LDAP SRV resource records, the "dc=ip6,dc=arpa" LDAP partition,
     and the necessary LDAP servers.
  
     The inetIpv6DelegationStatus attribute uses numeric code values.
     It is expected that IANA will manage the assignment of these
     values.
  
     Additional IANA considerations are discussed in [FIRS-ARCH].
