I'm trying to figure out how to get computer name resolution on my network.

I have a number of devices on my LAN, with device names "COMPUTER1" (IP 182.168.0.101), "COMPUTER2" (IP 182.168.0.102), etc. My router has IP 192.168.0.1. In this case, COMPUTER1 has a DHCP pool IP and COMPUTER2 has a permanent DHCP address reservation.

From COMPUTER1, I would like to be able to do a `ping COMPUTER2` and have it resolve the device name to the correct IP address. When I had the same devices on my consumer-grade ISP-provided modem/router device, this worked out of the box. On my ER8411 business router, it doesn't seem to work at all.

To clarify, from COMPUTER1, a `ping 192.168.0.102` works fine, but `ping COMPUTER2` times out with a "could not find host COMPUTER2".

Am I missing something obvious?
