DHCP handing out the wrong dns servers

I am using CentOS 4.4 and a setup I've been using broke this week.

In dhcpd.conf I have a global option:

option domain-name-servers hostname;

I also use this box as a firewall/router and now all of my LAN hosts
are getting their DNS set to the public IP from the WAN interface.

I can't tell if this is a named problem or a dhcpd problem.

For example "hostname" on this particular server resolves to resolves to 70.x.x.x. My windows hosts get the 70.x.x.x

Thanks in advance

Have you tried just using an IP address?
option domain-name-servers;

yes, that works. I am curious why the other way does not though.
