smurf... still?

I was looking through a modified copy of smurf.c I had (it listened on a port and when an incoming connection was detected, it asked for a host and then smurfed it--or so the documentation says, I just wanted to see how the port listening was achieved) and just wanted to check how many of the broadcasts in the default bcastaddr[] still were smurfable, and noted that the *very first one* was. How would I go about finding out the administrative contact for a network given its broadcast address? Specifically I'm looking for 165.154.1.255, but there are probably some others as well... root@narnia:~# ping -c2 165.154.1.255 PING 165.154.1.255 (165.154.1.255): 56 data bytes 64 bytes from 165.154.1.26: icmp_seq=0 ttl=241 time=287.2 ms 64 bytes from 165.154.1.66: icmp_seq=0 ttl=241 time=309.0 ms (DUP!) 64 bytes from 165.154.1.7: icmp_seq=0 ttl=241 time=338.9 ms (DUP!) 64 bytes from 165.154.125.53: icmp_seq=0 ttl=242 time=358.8 ms (DUP!) 64 bytes from 165.154.1.1: icmp_seq=0 ttl=241 time=388.9 ms (DUP!) 64 bytes from 127.0.0.2: icmp_seq=0 ttl=241 time=399.1 ms (DUP!) 64 bytes from 165.154.1.8: icmp_seq=0 ttl=241 time=418.8 ms (DUP!) 64 bytes from 165.154.1.57: icmp_seq=0 ttl=241 time=439.0 ms (DUP!) 64 bytes from 165.154.1.4: icmp_seq=0 ttl=241 time=449.0 ms (DUP!) 64 bytes from 165.154.1.21: icmp_seq=0 ttl=241 time=459.0 ms (DUP!) 64 bytes from 165.154.125.53: icmp_seq=1 ttl=242 time=219.8 ms --- 165.154.1.255 ping statistics --- 2 packets transmitted, 2 packets received, +10 duplicates, 0% packet loss round-trip min/avg/max = 219.8/378.0/468.9 ms root@narnia:~# (what the heck is that 127.0.0.2 doing in there...?) -- Daniel Reed <n () narnia n ml org> (3CE060DD) System administrator of narnia.n.ml.org (narnia.mhv.net [199.0.0.118]) What does not destroy me, makes me strong. -- Friedrich Nietzsche
