- RFC1033 also cites a legal name definition - exactly the same
- but including an underscore:
-
- The domain system allows a label to contain any 8-bit character...
- Because of other protocols restrictions, only the following characters
- are recommended for use in a host name (besides the dot separator):
-
- "A-Z", "a-z", "0-9", dash and underscore
-
- What is the reason for RFC952/1033 difference on this point?
