The IP address of a router has nothing to do with whether its manufacturer is Belkin, Linksys, Netgear, or any other company. An IP address is the address assigned by an ISP (internet service provider). You can learn your own IP address by right clicking on your internet desktop icon and fishing through the options. You can learn the IP address by clicking "turn on headers" in your email
. program. However, for security reasons, IP addresses do not reveal what they revealed ten years ago. If you have received malicious webpage hits or emails and wish to fish out the culprit, contact an attorney or the local police. Legally obtained search warrants can give more information about the prankster behind an email address than any prankster would ever want to know.
