Web site hosting: Determining the geographic coordinates of visitors to a web site? Their IP Addresses?
How does one determine the geographic coordinates of a visitor to a web site?
Google Adwords can narrow a person's clicks to a particular zip code. How accurate is this?
Clickcease.com does the same thing? And yet, when I examine the visitor logs of --let's just say as an example-- 1and1.com, There is no geographic coordinate information there. Where is Google and Clickcease getting this data?
How is Google adwords able to do this?

Example: They company I work for located in the USA and we have a office in England. At one time we had a private WAN connection and our only Internet connection was in the USA office. So when the employees accessed web sites, they would have the IP address assigned to our USA office, so it appears as if they were in the USA. So they would get ads for services that were no where near them.
If you look up the host name 1and1.com it resolves to 126.96.36.199. If I do a whois on that address I get that it is assigned to:
OrgName: 1&1 Internet Inc.
Address: 701 Lee Rd
Address: Suite 300
So if somebody from 1and1.com was accessing a web server that I ran from that IP address, I would detect they were there.
Just as a F.Y.I, there are DNS servers that also do geo location lookup so that they will send you to a different IP address depending on where the DNS server thinks you are located.
