Hello,

I am looking for a way to setup a redirection of users to my websites using their IP address.

Those who are with Vietnam IP will be direct to www.domain.com/vn and the rest of the world will stay on www.domain.com

Have you got any idea how to set this up

Thanks

There are a million different way to do this. But, to help, we'd have to know a little more.
What server are you using?
What server technology is it using?
What do you know how to do?

You will probably want to set up a geolocation database (to map IP to country) or pay for a service.

Thanks Paul for your feedback.

I am using now Linux Apache server with PHP and MySql

I am not a real coders but can play around with some scripts.

Can you help by suggesting some sites or services?

Start with this:
http://www.google.com/search?q=geoip+lookup

There's a group (I forget the name, just google around, you'll find it) that provides free data that you can drop into your MySql database.

Then you can use PHP to lookup a visitor's country code. If it's not allowed, just return a 302 to where you want them to go.

You keep the IP addresses of the vietnam in the database. And in the code of your home page, before serving the page, you check the browsers IP address with the IPs stored in the database. And then redirect to /vn/ if there IP address in found in the db.

You can easily buy the IP range from IPlocation.
