IP-Reservation: Hostname with underscore doesn't work

Hi, if i use underscore(or blank spaces) in Hostname i get following error? OR I missed something…not unlikely

IIRC the underscore is a reserved character in DNS rfcs. It is used in service names.

Correct–the underscore is not a valid character in a hostname. Hyphens are fine though.

Maybe a warning that states: “Underscores are not allowed in Hostnames because they are reserved characters in DNS rfc’s” would be the way to go in the red box instead of the current non explaining warning.
