Registering a domain name is not at all a hard task, just you need to select one and check its availability, and then proceed with a small process in any domain registrar website.
But first problem arises with the selection of the best registrar of a domain name, before the selection of a best web host. And many factors decide which registrar to go with for selecting and buying a domain name.

Here are the few best domain name registrars according to people that i have in contact –

Godaddy – The most rated and the best according to most of the people. Domain name is available for $9.99/year or lower, and the customer care support is always good and on.

Domainsite – A very decent, non complicated domain name registrar with very easy procedure of registering a domain name, with payments directly accepted from paypal too, without the requirement of a credit card. A .com domain name with google apps included costs from $6.99/year.

NameCheap.com – One more good one, with good customer satisfaction and no glitches in registering a domain name. A .com domain name costs $9.29. It is also an ICANN accredited registrar. You can also purchase SSL certificate and WhoisGuard along with the domain name.

Yahoo! Domains – A domain name costs $9.95 and its the most trusted, but a bit complicated when compared to other registrars. 24-Hour Toll-Free Support, private domain name registration and complete DNS control is allowed in Yahoo domain registration service. If you are new to the websites world, then Yahoo also provides a starter page to keep your website on till you make an actual website for the domain.

Network Solutions – $11.99/year for domain name registration. I hear few people suggesting this registrar but still i am away from it, as i already am too suspicious about it after i reported that it front runs domain names.

RegFly – Was RegisterFly, one of the well known one time, but then if you check the wikipedia page of it, you would see how many fraud reports of it were made and sent to ICANN. People claimed that Registerfly used to play and change the Whois data of the member’s domain names.
