Network DNS Question

I have a small home network with a linksys gateway/router/switch at the center. I have a few Windows XP nodes, and a pair of linux nodes with samba.

The DNS servers are picked up by the router (automatically), and sent to all the nodes. The DNS IPs belong to Comcast (my ISP).

With the DNS servers being automatically picked up by the router, I can ping by the hostname of the computers on the network. But I want to switch to OpenDNS.

I can manually point to DNS servers on my router. I set them to:
208.67.222.222
208.67.220.220

I reset all the nodes on the network. They pick up the new DNS servers, and the internet works fine. However, I can no longer ping by hostname. When I try to ping a node on the network by the hostname, I get something like this:

#ping bacon
Pinging bacon.hsd1.wa.comcast.net [208.67.216.132] with 32 bytes of data:
Request timed out.
Request timed out.

I can, however, ping by the internal IP.

How can I get back to pinging by hostname again with non-Comcast DNS?

It was an OpenDNS setting. You have to add "hsd1.wa.comcast.net" to your typo exception list.

Does anyone know how to change "hsd1.wa.comcast.net" to something like "home.local"?

It's in the router settings: Domain Name.

Here's the link to the help I got for the previous OpenDNS problem.
