pojednava sa o tom v RFC 1033, kde sa pise:

NAMES

   A domain name is a sequence of labels separated by dots.
[snip]
   The domain system allows a label to contain any 8-bit character.
   Although the domain system has no restrictions, other protocols such
   as SMTP do have name restrictions.  Because of other protocol
   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

co je celkom zaujimave. myslel som si ze su povolene iba ascii znaky, a ze
"_" nie je povoleny znak. o com svedci okrem ineho aj to, ze nie vsetky
resolvery ho spravne "resolvnu". ale o rfc sa tu uz diskutovalo dost,
vratane upozornenia, ze rfc nie je pismo svate:-)

vsetky rfc tykajuce sa domenovych mien najdete urcite v pripade rh-idnej
distribucie a rpm-ku bind-u v /usr/doc/bind-8.2.2_P5. iny adresar
nehladajte!!;))

S pozdravom
