Instead, try determining what the ips the host names resolve to (not the
other way around)  If you are GRANTing to someone@foo , you want to make
sure that when the machine 'foo' connects, it is connecting as the same
ip address the 'foo' resolves to when the server looks it up

for example,
	$ host foo
might translate to foo.domain.com -> 20.20.20.21 [external ip]
but foo is connecting as 192.168.1.21 [internal ip]
and Mysql will reject the connection.
