Would it be possible to wrapper everything in a script that uses a
single ping (ping -c 1) to pull the resulting IP address from the
output? For example:

ping -c 1 google.com
PING google.com (74.125.47.103): 56 data bytes
64 bytes from 74.125.47.103: icmp_seq=0 ttl=53 time=111.391 ms

--- google.com ping statistics ---
1 packets transmitted, 1 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 111.391/111.391/111.391/0.000 ms

seeing how that's the standard output for ping, couldn't you use grep
and a regex to grab the IP either from the parenthesis or that first
line? Of course there might be an easier way and/or better tool than
ping to do this.

CCing the list to get a discussion going as I imagine such a script
could have other uses.
