The 'address' return by accept is actually a packed sockaddr_in struct.

It can be unpacked using the functions sockaddr_in() and then the inet_ntoa() functions as shown in perlipc server example (which is linked from the perlfunc description of accept):

    for ( ; $paddr = accept(Client,Server); close Client) {
        my($port,$iaddr) = sockaddr_in($paddr);
        my $name = gethostbyaddr($iaddr,AF_INET);
        logmsg "connection from $name [", inet_ntoa($iaddr), "] at por
+t $port";
