Should this not be persuading, and we instead want to change to a more
permissive regex as suggested upthread, I suggest that we at least
mention RFC 5952 and strongly encourage it, maybe like this:
Sorry, the pasted patch came out really unreadable, here is a readable
version of the text I suggest to add to the draft:
The value in source_ip SHOULD either be a globally
routable IPv4 unicast address in the dotted-decimal
format, or a globally routable IPv6 Global Unicast
address in the canonical textual representation format;
see RFC 5952 for details.
That's OK with me with the usual caveat that you need to say why it's
SHOULD and not MUST.
Given that nobody seems to look at the regex, and just uses library
IP address routines to produce and read the IPs, how about just using the
really short one I suggested?
