What are the rules in regards to length of the domain, characters to be used in a .DM domain name?
The syntax rules that will apply for the registration of a .DM domain name are as follows:
a) The only valid characters for a domain name are the english alphabet letters (from a to z), normal digits (from 0 to 9) and hypens (-). The domain name does not distinguish whether the letters are small or upper caps;
b) The domain names cannot begin nor end with a hypen (-) nor have two hyphens (--) in it;
c) The minimum length for a second-level domain name is three (3) characters, and the maximum length of a domain name is 63 characters.
