Once again my apologies if my search fu is not worthy enough. I did do some searchs on this both in the forums and with wiki and google but unfortunately could not find something that my answered my query sufficiently.

That and I'm at work on a Thursday night working at Noise Control so yeah the phones may go crazy soon (especially at 3.30am bar closure time :()

This forum has been a font of knowledge that I feel pretty confident asking you guys this. I'm a fairly approachable guy so if you tell me I'm an idoit for doing it this way I don't mind :) . Just be sure to tell me the correct way I should be doing it :)

I make a lot of posts on the World of Warcraft forums analysing peoples traceroutes.

Part of what I do is I look at the actual geographical location for each hop and ask myself is that a reasonable latency considering the distnace ?

To do this I've just been passing it through a whois search at domain tools.com but I'm concerned that may not be the most accurate way of judging it. That is I look at address it's registered under.

Maybe I should be taking the host name it resolves to and pumping that through the whois would that show the physical location of the IP address ? How about airport codes are they that reliable for judging a IP address location ??

For example this IP address here :  

152.63.30.2

I seem to get confliction reports of where it's geographically located :(

Are there more accurate ways of finding out the geographical location of an ip address. For example I found out about this www.geoiptool.com would this tell me a more accurate geolocation ?


Help please .... show me  how to do it please :)

apologies for the long post ..looks like I live up to my signature :)

EDIT :

Here's an example of my confusion


http://whois.domaintools.com/152.63.30.2

IP Location:
United States United States Ashburn Mci Communications Services Inc. D/b/a Verizon Business


Resolve Host:
0.so-4-1-0.XL3.IAD8.ALTER.NET


http://www.geoiptool.com/en/?IP=152.63.30.2

Somewhere in Kansas

http://www.ipligence.com/geolocation

Ashburn, VA

http://www.world-airport-codes.com/united-states/washington-dulles-international-7540.html

Search for Airport Code IAD

Listed in Chantilly, VA 20152, USA

Which according to google maps is 15 minutes from Ashburn.

I just answered my own question didn't I ?  :roll:

Would still like people's inputs as to any possible errors in my method :)

AFAIK "whois" info will tell you the domain (and so the mapped ip) "owner's geographical location, the hosting provider's geolocation and the reistrar's geolocation, all of which can be very different.

I can show you a whois record where the owner is in France, the hosting provider (where the servers actually are plugged in) is in Germany and the registrar in Canada.

By the sound of it, it's the second of these you would be interested in.

If I've understood your question correctly, this might explain some of the confusion. On the other hand it may not ;)

its not really useful to find geographical location because internet is network-centric instead of geo-centric. There are 3 instances when geographic location of a network is really useful: when a hop crosses a really big ditch (eg pacific ocean) which adds over 100ms to the response time (basic physics), when a backbone node in one area is congested, and when traffic is being routed in a loop from a node with a broken routing table. Those cases are easy to see by the ping times and reverse DNS displayed by the traceroute, and if there is a problem then its the route itself thats useful instead of the location of the node. Whois lookups dont say where all the nodes are if they do their own routing, only where the hosting provider is that manages the range of IP addresses.
