As of 7/29/2002 EPIC fully supports IPv6 in server descriptions, server connections, $connect(), $listen(), /DCC GET, Virtual Hostnames, $iptoname().
Surround the ipv6 p-addr with square brackets:
/server [1:2::3]:…
You can now connect to servers via IPv6!
$connect(<host> <port> <family>)
where <family>
is “4”, “6”, “v4” or “v6” and <family> is optional.
$listen(<port> <family>)
where <family> is “4”, “6”, “v4” or “v6”
and <family> is optional.
$iptoname(<p-addr>)
Both IPv4 and IPv6 “p-addrs” (ie, A.B.C.D or
A::B:C) are now supported.
If the hostname that you choose as your virtual hostname has an IPv6 address, then that IPv6 address will be used as your virtual host if you connect to a server via IPv6.
