Example: You're ISP holds a domain ispx.tld, and is assigned a prefix 1234:5600::/24. Your site, sitex.tld, is given IPv6 prefix 1234:5678:9abc::/48. Here's the relevant part of the ispx.tld zone: $ORIGIN ispx.tld. @ IN SOA ... ipv6 IN A6 0 1234:5600:: sitex IN A6 24 0:0:78:9abc:: ipv6 And sitex.tld's zone: $ORIGIN sitex.tld. @ IN SOA ... ipv6 IN A6 48 0::0 sitex.ispx.tld. ; optional subnet1 IN A6 48 0:0:0:1:: ipv6 ; or, replace ipv6 with sitex.ispx.tld. host1 IN A6 64 ::2a0:80ff:fed5:55a9 subnet1 Where the format for an A6 record is as follows: <domain> IN A6 <prefixlen> <suffix> <prefix-domain> <prefixlen> is the prefix len of <prefix-domain>'s IPv6 address, not of <domain>'s IPv6 address. <suffix> is appended to <prefix-domain>'s IPv6 address to form <domain>'s IPv6 address. In the above example, the following would be assigned: ipv6.ispx.tld has 1234:5600:: sitex.ispx.tld has 1234:5678:9abc:: subnet1.sitex.tld has 1234:5678:9abc:1:: host1.sitex.tld has 1234:5678:9abc:1:2a0:80ff:fed5:55a9 There is also a much more complex example in rfc2874 [www: http://www.ietf.org/rfc/rfc2874.txt ], beginning with section 5.1. -- Aaron J.
