Experience has shown that there are a number of DNS zones all Experience has shown that there are a number of DNS zones all
iterative resolvers and recursive nameservers should, unless iterative resolvers and recursive nameservers should, unless
configured otherwise, automatically serve. RFC 4193 specifies that configured otherwise, automatically serve. RFC 4193 specifies that
this should occur for D.F.IP6.ARPA. This document extends the this should occur for D.F.IP6.ARPA. This document extends the
practice to cover the IN-ADDR.ARPA zones for RFC 1918 address space practice to cover the IN-ADDR.ARPA zones for RFC 1918 address space
