I had tracked an IP address from a threatening email that I had recieved to a Cox Communications host that was in San Mateo, CA at one point, and than an hour later it was showing it in Eureka, CA which as some know are not close cities. Now my only confusion is that Cox does not provide any wireless services that I know of. I have figured out that this place might be a business, and most businesses run off of servers that should not travel via satellite. Why would a business server hit one satellite, and than another so far away in such little time? Please help, as I am very confused and would like to rest easy. Thanks =]

An IP address is assigned to an organization for their use -- generally they are quite static when used by high speed connections, but they can be dynamic when used by dialup. In general, without the assistance of the party who is responsible for teh IP address (Cox in your case), you cannot pinpoint with any accuracy the location of the current user.

There are programs that hackers use which allow them to change IPs frequently so that no one can track them ... it could be this, or it's just an IP which was used by someone, then this someone is disconnected, and someone else connected and that IP was allocated to him/her ...
