Domain names
A domain name can contain all 26 letters, 10 numbers, and a hyphen (-). You cannot start or end a domain name with a hyphen. Domain names are not case sensitive, so you can use upper and lower case letters interchangeably. A domain name can be up to 67 characters long — including the 4 characters used to identify the Top Level Domain (.net, .com or .org).
A little known fact is that you CAN have multiple dashes right next to each other. (e.g. domain--names.com) Opened up a few more possibilities? There is one restriction: Double Hyphens in the third and fourth position are not allowed. e.g. XX--XXXXXXXX.com. This allows for IDNs and other encodings.Results
All three letter .com domains are taken. However, there are still 3 character .net and .org domain names.
.com – All three character .com names are registered.
.net – All three letter, or all 3 number names are taken. All LLN (Letter Letter Number) or anything with a hyphen is taken.
.org – All three letter, or all three 3 number names are taken NNN.org, and LLL.org. All L-L.org domains are taken. Checked the N-L.org, L-N.org, and N-N.org. Looks like there are a number of hyphenated 3 charactor .org domains left, but they all contain numbers.
I just wrote and ran a bash scripts to check all three character .org domains.
