IP en base 10

IP addresses can be converted to a "base 10" number. Spammers often use this in URL's. Example: http://123456789/.

If the URL contains "@" ignore everything to the left. http://junk@123456789/ is the same as http://123456789/

A standard IP is "base 256." To convert 66.46.55.116 to base 10 the formula is:
66 x (256)3 + 46 x (256)2 + 55 x (256)1 + 116 = 1110325108

http://66.46.55.116 http://Network-Tools.com http://1110325108 are identical.
