35 What I would say in this case is, that there will certainly be hosts,
36 Of which the address cannot be resolved by the ircd, so that the
38 Will appear in ipv6 address.
40 Moreover, the NICK line of certain ircds, can only do conversion of
41 Ipv4 addresses into the longip, but ipv6 addresses cannot be converted
42 In such a way, so that they probably (on tr-ircd for sure) appear as
45 Since services does support SZLINE, which depends on the IP of the user,
46 Services must work correctly when storing ip addresses received via the
49 If services would try storing them into u-
>ip where ip is char ip[
15];
50 You would then live in interesting times.
52 Thats my case, which means, services should check if there are arrays of
54 Which would be too small for ipv6 addresses. Its not only doing
