Can't delete grayed-out DNS server addresses

I want to replace two grayed-out DNS server addresses from the Network panel (under the DNS tab in "Advanced…"), to replace them with OpenDNS settings. But they can't be selected/deleted. How do I get around this problem?

24 inch Intel Core Duo, Mac OS X (10.5.5), 2.8 GHz, 2GB ram

I want to clarify that if you simply add the open DNS servers using + in network system preferences those servers will be used first and the grayed out one provided by the internet provider last even though the newly added servers will be listed below the grayed out one in system preferences.

That is correct - those are provided by your router and can not be deleted - you can add Open DNS servers (click the + sign) or log into the router admin page (I recommend this way) and have your router use the Open DNS servers fro everything on your network (this will change the grayed out ones)

Thanks. Have added the OpenDNS servers, rebooted for good measure, and now the default addresses are simply ignored. Everything works fine!
