Actually, it's even a little more subtle than that. An underscore may be
legal in an alias for some query types, and illegal for others. For
example,
in
foo_foo in cname bar
bar in a 10.0.0.1
bar in txt "Comment"
For an address query, foo_foo is an illegal owner name. For a TXT
query, foo_foo is legal.

Hyphens are allowed in the labels of domain names as long as they're
not the first of last character of the label.
