111.Added $dns(N) identifier, used in the on DNS event to list the
address that was resolved and any associated IP addresses.
Properties: nick, addr, ip. $dns(N) without a property returns the
address being resolved. You can use N = 0 to return number of IP
addresses found.
Note: the old identifiers $iaddress, $naddress, and $raddress are
still supported but are no longer listed in the help file.

22.Added 1:ON DNS:/echo $nick $iaddress $naddress $raddress event.
If /dns <nick> was used then $nick refers to <nick> otherwise
it refers to your own nickname. $iaddress refers to the ip
address, and $naddress refers to the named address. $raddress
is the resolved address. If $raddress is $null then that means
that the address could not be resolved.
