There are two main types of domain registration lookup. They are each used for two completely different purposes. The first type is used to search research and find available domain names. The second type of domain registration lookup is the kind when you want to find the owner of a domain name, or information about it. Depending on what your goal is of your domain search, depends on what types of sites you want to search.
If you are looking up a web domain to purchase and want to know the availability, you would do your domain registration lookup at a domain registrar or a web hosting company. If you read my other articles, you will learn that I highly recommend registering your domain name at your hosting company, instead of vice versa.
Some common registrars and hosts are: GoDaddy, Register, HostGator, etc., you can go to any and do searches for a domain name or keywords and they will tell you which domains and extensions are available, maybe the.com or.net versions are not available, but.org is, you never know until you do a lookup.
Also, some companies give you really good suggestions if your name is taken, as always, use different sites to get different ideas that they give you, but once you actually register it, do it at your hosting company for convenience of DNS and setup speed factors.
The other type of domain registration lookup, is when you are trying to find information about an already registered name. Some examples are: the owner information or other technical specifications like WHOIS information, registrar or hosting company, IP address, DNS settings, expiration date, etc.
To find this you use sites like DomainTools, Whois, etc. You can also find this information when you are searching for domains, if the domain is taken, usually in small text it says something like more information or whois data, and you can find this information while you are also using the other type of domain registration lookup type.
Well, those are the Two different types of domain name lookup methods,
a. One is for finding new unregistered names, and
b. The other is for finding currently registered name information.
I wish you much luck finding great names and also getting the info you need, when you need it.
