dns64
Name
dns64 - enables DNS64 IPv6 transition mechanism.
Description
From Wikipedia:
DNS64 describes a DNS server that when asked for a domain's AAAA records, but only finds A records, synthesizes the AAAA records from the A records.
The synthesis in only performed if the query came in via IPv6.
See RFC 6147 for more information.
Syntax
dns64 [PREFIX] {
[translate\_all]
}
- [PREFIX] defines a custom prefix instead of the default
64:ff9b::/96 translate_alltranslates all queries, including respones that have AAAA results.
Examples
Translate with the default well known prefix. Applies to all queries
dns64
Use a custom prefix
dns64 64:1337::/96
# Or
dns64 {
prefix 64:1337::/96
}
Enable translation even if an existing AAAA record is present
dns64 {
translate_all
}
prefixspecifies any local IPv6 prefix to use, instead of the well known prefix (64:ff9b::/96)
Bugs
Not all features required by DNS64 are implemented, only basic AAAA synthesis.
- Support "mapping of separate IPv4 ranges to separate IPv6 prefixes"
- Resolve PTR records
- Follow CNAME records
- Make resolver DNSSEC aware. See: RFC 6147 Section 3
