[Freeipa-devel] [PATCH] discussion needed: 0009 Support for IPv6 elements in idnsForwarders attribute

[Petr Spacek]

Hello,

this patch fixes https://fedorahosted.org/bind-dyndb-ldap/ticket/49 , 
but I want to discuss one (unimplemented) change:

I propose a change in (currently very strange) forwarders syntax.

Current syntax:
<IP>[.port]

examples:
  1.2.3.4 (without optional port)
  1.2.3.4.5553 (optional port 5553)
  A::B (IPv6, without optional port)
  A::B.5553
  ::FFFF:1.2.3.4 (6to4, without optional port)
  ::FFFF:1.2.3.4.5553 (6to4, with optional port 5553)

I find this syntax confusing, non-standard and not-typo-proof.


IMHO better choice is to follow BIND forwarders syntax:
<IP> [port ip_port] (port is string delimited with spaces)

(From: http://www.zytrax.com/books/dns/ch7/queries.html#forwarders)


*Current syntax is not documented*, so probably is not used anywhere. 
(And DNS server on non-standard port is probably useful only for testing 
purposes, but it's another story.)


What is you opinion?
