Is an underscore ' _ ' a legal character in a DNS name? Is there an
document that someone can point me to with a definitive answer as to
which

Yes. DNS is a general purpose distributed database.
There are restrictions on which characters are legal in hostnames but those

rejected by the bind software so many people used it anyway. Eventually
the software was
