unbound/doc/README.DNS64

   1 The DNS64 code was written by Viagenie, 2009, by Simon Perrault as part
   2 of the Ecdysis project.  The code is copyright by them, and has the BSD
   3 license (see the dns64/dns64.c file).

   5 To enable DNS64 functionality in Unbound, two directives in unbound.conf must
   6 be edited:
   7
   8 1. The "module-config" directive must start with "dns64". For example:
   9
  10     module-config: "dns64 validator iterator"
  11
  12 If you're not using DNSSEC then you may remove "validator".
  13
  14 2. The "dns64-prefix" directive indicates your DNS64 prefix. For example:
  15
  16     dns64-prefix: 64:FF9B::/96
  17
  18 The prefix must be a /96 or shorter.

  20 To test that things are working right, perform a query against Unbound for a
  21 domain name for which no AAAA record exists. You should see a AAAA record in
  22 the answer section. The corresponding IPv6 address will be inside the DNS64
  23 prefix. For example:
  24
  25     $ unbound -c unbound.conf
  26     $ dig @localhost jazz-v4.viagenie.ca aaaa
  27     [...]
  28     ;; ANSWER SECTION:
  29     jazz-v4.viagenie.ca.        86400   IN      AAAA    64:ff9b::ce7b:1f02
