Re: IP address to Hostname

It's actually f1.www.vip.re1.yahoo.com. www.yahoo.com is just an alias. gethostbyaddr is what you want.

By the way, Net::DNS is overkill to resolve domains. Socket's inet_aton is sufficient.

Not only is Net::DNS overkill, but using Net::DNS means you're committed to using DNS to do the domain name resolving. While that may work on many machines, `gethostbyaddr` will actually use the resolving that's configured for the system. Which, beside DNS, may consist of files, NIS, NIS+, LDAP, ... or some combination of resolving.	[reply] [d/l]
