In the past, we maintained a list of the available Domain Name Extensions around the world. The list was broken into three main groups, world-wide domain names, generic domain names, and coutry specific domain names.
As of 2014, there are now so may extra domain extensions, it is almost impossible to list them.
As of 2016, there is even more choice, that the only sensible way to find a domain is to do full research, based on the requirements for the site. With so many specific extensions (specific to business type or geography) there is a domain name for everything.
If you would like us to do the research for you, please contact us.
