Do I (EU) play WvW on american servers?
IP locations are not accurate. They’re registered by their owner. All NCSoft’s IPs are registered as Austin, Texas, which is their NA datacenter.
It’s nearly impossible to determine where an IP truly is. To get a more accurate location, tracert the IP and look at the hops it goes through. Use the response time between each hop to roughly estimate the distance. Going overseas for example is going to cost ~100ms.
For example, if I tracert 206.127.159.163, the hop prior to NCSoft’s network is a link to Telia (62.115.43.74). If you lookup that IP, it’s registered to Frankfurt, Germany. Since the change in response time was ~2ms, that would be impossible to go from Germany to Texas. One of them has to be wrong. Go through each hop to get a more accurate picture.
