we are planed to start an own webserver for our website. can any one give me a tips for own webserver requirements and how to allocate domain names for some other new websites.

That is lot of work, may be you can contact a web designer at websites like http://getafreelnacer.com/ to code it for you.

u can get domain from www.rediff.com

and u can make your own pc as server...(if not much space require for your website) (depends)

www.webhostingtalk.com has a lot of discussion on this.

Basically you need to purchase a domain name. This will allow you specify a name server (you can run your own or use someone elses) and this will direct visitors to your IP for your site. You will also need to run a DNS server if you play to host subdomains.

To run your own webserver for your own website, you need to contact your internet provider. They can set you up with a "static IP address" which is what you would need to host your own server at your home or place of business rather than at some other facility.
