Yes, you have a point. Actually it looks like newer version of DNS do all=
ow it=20
but the 1985 (sic!) RFC 952 explicitly mentions only A-Z, . and - as beei=
ng=20
allowed in names. The special meaning of the . is well known.

Side Note: This rather old RFC also makes other rules which are not follo=
wed=20
today anymore like the naming of gateways...

On the other hand this RFC does not forbidd using double hyphens?!

What about changing from "_" to hyphen "-"?

Yours,

P.S.: All my tests with recent DNS servers did work without problems.
