Although there are many ideas being floated about what new Top Level Domains can be created. There may not be enough articles explicitly showing what cannot be created because they already exist or are reserved names that won’t be able to be issued because of the rules. Amongst the many rules put forth by ICANN for new TLDs, one of the most basic ones is that a new top level domain must not be the same as an existing top level domain (or even too similar).
I’ve seen several different figures about how many top level domains exist today. My count from perusing ICANN’s site is 284. But then there are at least 34 “reserved names” which means that any new registry will have to prevent at least these 34 strings from being issued. I don’t think you’ll be seeing anyone getting these strings to the right of the dot as well. That means that in their most basic forms, there are at least 318 existing strings that you will surely not be able to get as a new top level domain.
An interesting (hypothetical) example could be GM. General Motors is not going to be able to get GM.COM (that is assuming they want a new TLD and they have not publicly indicated that they do; I’m just using this as an example). .GM is already allocated to the country of Gambia. Now that doesn’t mean GM can’t pay the government of Gambia to let them use .GM. Many ccTLDs are already being used for reasons different than their original intent because of agreements with governments (e.g. .tv, .fm, .me…). Since GM’s gross revenues are 30 times that of Gambia’s GDP, it would seem that they could to cut a deal if both parties wanted to. Who knows? Maybe it would be cheaper for them that way :-). But GM is not getting .GM any other way.
On top of the stated problem, new TLDs have to be at least 3 letters in length. (Note: The longest they can be is 63 characters and they cannot include numbers). So maybe they can get .GMC?
Even that could be problematic since it is very close to .GM. Only time will tell how these things will go. For a while, a company that contracted with ICANN had a TLD string analyzer online where they claimed you could get some idea of how close two strings of characters were and if they were too close to be considered using an algorithm they developed. Unfortunately, as of this writing, the web page hasn’t worked for several weeks and I’m not sure if it ever will. This was the address. Hopefully it will begin to work again soon: http://icann.sword-group.com/algorithm/Default.aspx
So that all said, below is my list of the TLDs that are “already taken” and that will have to be considered in any application made.
I apologize to my ICANN associates if some of this seems elementary, but condensed lists like this are helpful to me and, I think, to others that don’t dwell in this industry on a day-to-day basis.
Feel free to use this list to match up against your ideas. Remember that this is not an official listing; just my personal research. I list these here just for convenience. I apologize and take no responsibility for any errors or omissions:
