[dns-wg] Re: [db-wg] Proposal to change the syntax of "nserver:" attribute

It would be helpful to include details about the accepted syntax for these 
addresses. For instance:

[ipv4_address] is an IPv4 address of the name server in dotted quad form

[ipv6_address] is an IPv6 address of the name server in the preferred 
textual canonical form (Sect 2.2.1, RFC 4291)
The IPv6 textual compressed form (Section 2.2.2, RFC 4291) is/is not 
accepted (cross as necessary).
The IPv4/IPv6 textual mixed form (Section 2.2.3, RFC 4291) is/is not 
accepted (cross as necessary).

> nserver: ns1.example.com 168.0.0.1

It would be better to use RFC 3330 documentation IP addresses, e.g.

nserver: ns1.example.com 192.0.2.0

Best regards,
Marcos

P.S. Btw, if non-preferred IPv6 textual forms are accepted, will the 
output of e.g. whois deliver the original or the preferred form?
