Red Hat Bugzilla – Bug 6304
ping no longer accepts IP addresses as >32-bit integers

As an easy way to do the conversion to see the dotted-quad
IP address of spammer websites posted as
http://225179979697167/, I used to use ping. i.e.
[jlewis@sloth jlewis]$ ping 225179979697167
PING 225179979697167 (188.8.131.52): 56 data bytes
Ping from Red Hat 5.2 would take the lower 32-bits of the
number, and use it as the IP. Red Hat 6.0 won't accept
In Red Hat 6.1, ping gives:
[jlewis@gsvlfl-ns-1 jlewis]$ ping 225179979697167
ping: unknown host 225179979697167
[jlewis@gsvlfl-ns-1 jlewis]$ ping 3434302479
PING 3434302479 (184.108.40.206) from 220.127.116.11 : 56(84)
bytes of data.
I could not reproduce this on a Redhat 5.2 system (+all updates) running 2.2.16,
or recompiled on a newer system, so I guess this is an issue with libraries/headers.
Nonetheless, I don't think this kind of broken behaviour should be supported.
This won't work in other newer systems anymore either (e.g. FreeBSD 4.0).
