Non-authoritative answer:
166.188.77.208.in-addr.arpa name = www.example.com.
You can do a reverse DNS lookup with host, too. Just give it the IP address as an argument:
$ host 192.168.0.10
server10 has address 192.168.0.10
The other answers here are correct - use reverse DNS lookups. If you want to do it via a scripting language (Python, Perl) you could use the gethostbyaddr API.
You can use traceroute command as well.

just use the traceroute it will show you the routing path with host names (IPs resolved)
