My older brother has something of a mania when it comes to DNS. He is always looking up who tried to gain access to his computer, where that person was located, why he wanted to do it, and if there were a way of figuring out what color of socks that person was wearing I bet he would try and learn that too.
If the same happens to you, first of all – take it easy. Second, you will be glad to know that this online resource gathers together an endless series of DNS tools and utilities, all of which are browser-based, and which can be employed for free.
For example, reverse lookup functionality is provided along with a port check and a “Get DNS Records” feature. Besides, routes can be traced in an effortless fashion and you can always fetch WhoIs results by pasting the address on the provided input box.
Granted, this is not the kind of site that will appeal to a large public. But I felt it was important to cover it since these tools (when used judiciously) can give you a better overall understanding of the Internet as a whole.
