Domain registration companies provide a name look-up service that will determine if your requested name is available
for purchase. In addition to helping you register your domain name, these
companies will usually host your website, which is step 3 in the
website design process.
Select
Whois.Net
to see if a domain name is available or already in use.
If it is already in use, the site will provide you with the domain
owner's name, where the site is being hosted, and a link to the person's website.
You might be able to purchase the domain name from the owner if the domain
name is important to you.
