Incorrect.  'Nslookup' doesn't care.

Underscores are illegal in host names.  If the original questioner
checks his log files, I suspect that he will find that 'named' will not
accept this name.  But even more so:

"A" records must have IP addresses on the right hand side.  If you are
using the name [without underscores] as an alias for another name, this
should be a "CNAME" record.

Yes, there is.  But it can't force all other name servers to accept
this illegal name.

The option is:
       [ check-names ( master | slave | response ) ( warn | fail | ignore); ]
e.g., if you say:

	check-names master warn;

then it will be accepted but warn you of the error of your ways.

The defaults are:
	check-names master fail;
	check-names slave warn;
	check-names response ignore;
