RFC 1035 isn't the only RFC under this aspect. While in RFC 1035 the host specification is a "should", in other RFC's it's a "must" They are: RFC 1123 Requirements for Internet Hosts -- Application and Support which has a pointer to RFC 952 DOD INTERNET HOST TABLE SPECIFICATION So, underscores in Hostnames aren't allowed. They are not forbidden in the DNS specification (you can in fact use underscores in different context in DNS), but because of the RFC's above. You should also take a look at RFC 2181 Clarifications to the DNS Specification specifically Section 11 Daniel Evren Yurtesen schrieb: > > Well, I am the person who has this problem. > The RFCs does not explicitly say that we should not use underscore > character > as far as I understood.
