Old format was:

USER username username address :real name

New format is:

USER username 0 * :real name

And now spaces are automatically replaced by underscores in username (since no space is allowed here).

I just have read again the RFC1459 and RFC2812, both says that this argument is unused (used only for connection between two servers, according to RFC1459).

So I will just send "*" here instead of an address or a hostname (as suggested in RFC2812).

In various other cases (such as some server-server protocols), "0::1" is usually used because it represents the same address as "::1" while avoiding protocol breakage. (This of course applies to all IPv6 addresses starting with ::, which is just a bunch of 0000's collapsed.)

But with the USER command coming for clients, most ircds simply ignore the 2nd and 3rd fields, so anything that does not start with a ":" would be acceptable (for example, "[::1]" or just "*").

When I connect to ::1 via IPv6, this is what weechat sends:

USER compiler compiler ::1 :Florian Bruhin

This means the value ":1 :Florian Bruhin" is taken as the server name. According to grawity in IRC, 0::1 would be the correct thing to send.
