(ba)sh - Determine (based on machine name) whether a computer is on the local network

Working on a shell script that takes a machine name as an argument and then determines if the host is on the local network (same network as the machine that ran the script).

How can I get the IP address from the machine name? Once I get that I should be able to compare that IP with the local one to see if they're on the same subnet.

What do you mean by local network? subnet or (windows) domain or within LAN?

You may also have a look at traceroute utility.

You can use nslookup (http://linux.die.net/man/1/nslookup), dig (http://linux.die.net/man/1/dig) or host (http://linux.die.net/man/1/host) command-line utilities.

For example, here is the result of running host for getting A-records for stackoverflow.com from DNS server:

$ host -tA stackoverflow.com
stackoverflow.com has address 69.59.197.21
