DNS or loadbalancer

Dear all,

When i visits to, it redirects me to when i am in UK, my browsers hits to and when i am in US it redirects url to (USA).

I want to know, how this happens, either its related to DNS or URL redirector?

I would hazard a guess and say IP based redirection at the web server, not dns.
given that your isp has a unique block of IP's and that block has a known geographical location.

your ip is sent to the web server when you request its junk.

nslookup and ping of give me, not
that said, I am in australia, I dont get that redirection anyway.

also, I didnt think dns was that clever.

in order to implement something like that yourself..

you can make use of a geolocation service.. which cost money (google geolocation)
write a little php script which gets the IP from the request and matches it to the right location, then sends an html redirect header.

or probably a bit of a kludge but, when I tracert my IP address, it's last hop (me) is
again, with a script, you could tracert the users IP, and then with regex or some other sort of text matching doodad, extract the country code of the last hop (in my case .au)
and then redirect to the appropriate location.

that said, today is the first I have looked at geolocation, there is likely a much better way to do this.
