DNS lookup with a twist.

What I need is a script which, when the user puts in domain, it pings DNS servers around the world (use registrars) to check where the DNS is pointing to. This is to see how close a domain is to completeing DNS changes. After it chesk, it should output it in list form as well as on a map, with colors. IE, if North America is pointing to [login to view URL], and the rest of the world is pointed to [login to view URL], it would assign a certian color to each, and put dots where it was pinged, and the dots should be colored according to which dns. Should also include a cache that saves for 1 hour, so if the same domain is searched twice within an hour, it doesnt ping the 2nd time, just shows the same info. After that hour, if searched, it repings. It should also include an option to make it memebrs only, and have those accounts be paid for. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Exclusive and complete copyrights to all work purchased.
