Ben's Bits

If you're responsible for running a server on the internet or just curious about your IP address you can find out all sorts of useful information at robtex.com. For example if you run a mailserver you can check your mailserver against a number of popular blacklists all at once. You can also check reverse DNS information for your IP address, whois information on a domain, routing and AS numbers. This makes robtex.com quite the multipurpose IP tool and one I'm bound to use again.
