When you have the site name (the DNS) and you need the IP address (the numerical string), you can get that by doing a PING. Easy enough!
But, what can you do if you have an IP address and you want to know the DNS or alpha name for the site?
First you need to realize that you won't find every site here. But maybe if we can get everybody to register their sites, this type of stuff can become a greater resource. That may take a while. In the meantime, here are a few tools that might come in handy:
- A site that provides a geographical location of the site IF the site has been registered. Most are NOT!
- A site that provides a DNS Resource Directory with just about everything you'd ever want to know about DNS/IP stuff. No, I haven't read it all yet!
- There's also a slick piece of free softward called the URL Discombobulator for playing with URL numbering
