What are the rules/restrictions of domain names?
1) The Third Level Domain may only contain the following thirty-seven characters ("Characters") or a combination thereof:
2) the twenty-six unaccented Roman letters (i.e. a-z inclusive);
3) the ten western digits (i.e. 0-9 inclusive); and
4) hyphens.
* The first or last Characters of a Third Level Domain may not be a hyphen.
* 101Domain does not offer Internationalized Domain Names and so domain names that start with the characters "xn--" (i.e. "xn" followed by two dashes) may not be registered.
A Third Level Domain may not be one character long. For example, an application to register "1.co.uk" or "a.co.uk" would be rejected.
For the SLDs co.uk, me.uk, org.uk, and net.uk, a Third Level Domain may not consist of only two letters. For example, an application to register "ie.co.uk," "-a.co.uk" or "e-.co.uk" would be rejected. For the avoidance of doubt, Third Level Domains containing a letter and a number or two numbers are permitted ("2a.co.uk," "a2.co.uk," or "22.co.uk" are acceptable).
Until further notice, the Domain Name (e.g. internet.co.uk) may not be more than sixty-four Characters long in total, including the SLD and TLD. We intend to allow longer domain names, where the third level domain has a maximum of 63 Characters.
For the SLDs co.uk, me.uk, org.uk, and net.uk, a Third Level Domain may not be identical to any existing SLD (as listed in Appendices A, B and C to the Rules), or any SLD under .uk the creation of which has formally been announced by Nominet. For example, an application to register "org.co.uk" or "nhs.co.uk" would be rejected.
For the SLDs co.uk, me.uk, org.uk, and net.uk a Third Level Domain may not be identical to an existing TLD or any TLD the formal approval of which has been announced by ICANN (or any replacement body which controls the creation of new TLDs). For example, an application to register "uk.co.uk.," "eu.org.uk," or "com.co.uk" would be rejected.
