Understanding the ITS DNS Naming Conventions
ITS follows DNS naming conventions for all domain, net, gateway and host names:
- Names must be a text string drawn from:
- the alphabet (A-Z)
- digits (0-9)
- minus sign (-)
- dot (period) (.)
- Dots are allowed only to show domain hierarchy.
- Names must be at least 2 characters long and preferably be no more than 14 characters long.
- Single character names are not allowed.
- UTnic will consider exceptions for names that are greater than 14 characters (up to 63 characters).
- No blank or space characters are permitted as part of a name.
- The first character should be an alpha character.
- While RFC 1123 relaxed the RFC 952 restrictions to allow either a letter or a digit as the first character, UTnic prefers to follow its original naming conventions.
- The last character must not be a minus sign or period.
- Names are not case sensitive. No distinction is made between upper and lower case.
- Only hosts which serve as GATEWAYs should have "-GATEWAY" or "-GW" as part of their names.
