Only for TCP based connections naturally.

It does a reverse lookup on the address and then a forward lookup on the
resolved name to ensure that it's not being faked in the DNS.  Remember
that access control for TCP based connections is via hostname so it's
important to verify that the name is correct.

For local connections which would be the normal use of mSQL, this isn't an
issue.
