Google automatic redirect

Whenever I type www.google.com, the site is getting automatically redirected to www.google.co.in , what is the functionality behind this automatic redirecting?
How google is doing this?
Any idea!
Any help is appreciated.
Regards.

It would seem google takes the IP of the requester and redirects to appropriate server.

1)Is it possible to identify the country name from the IP address?
2)The IP address is that
My machine's IP address or internet dynamic IP address?
3)If it's dynamic IP address, then for each page I open in different sites, does each webserver give it's own IP address.
Suppose if i open 10 sites, then does it mean that i'll have 10 different IP addresses?
Regards.

Yes, you can lookup the location based on your IP.

If you are directly connecting to the Internet, your machine IP will be a public IP. But if your company uses a router and your machine is part of a NAT subnet, it will have a private IP with the router having the public IP.

3)If it's dynamic IP address, then for each page I open in different sites, does each webserver give it's own IP address.

Your machine will be assigned an IP address at the time it starts up (more specifically when networking module starts up). After that the IP doesn't change unless you restart networking.

Well, if you are in office, you have an ip address. your lan-server provides you that ip. similarly if you are on internet it is your internet-connection-provider that provides you an ip.

We simply believe the fact that internet-service-provider is located at some place or region and that you should also be from that region or around. You can create database to store all such ip-to-region mappings. That is what the link by satish should be doing behind the scenes.

In this particular scenario I dont think Google (or any other site) will need the originating IP address. Maybe the address of the last router will suffice. But yes the client IP is the best way to know where the request comes from.

google do redirect the request based on the ISPs ip address.

On google homepage it is on Bottom-Right and on the article page it is botttom-left (part of copyright). ;-)

Is it possible for us to view or know our IP address?
If yes how?
Regards.

Look at Satish Chilukuri's post and the link in that.
