On the Status > LAN tab of DDWRT I am seeing the DHCP clients I'd expect like:

wks1 192.168.2.104 12:33:A2:0B:8F:58 1 day 00:00:00

But also these:

* 10.10.2.139 90:E2:BA:02:E5:24 1 day 00:00:00
BMC*dhcp 10.10.2.109 00:14:22:7B:05:E7 1 day 00:00:00
* 10.10.2.106 51:FB:69:E0:5F:89 1 day 00:00:00


Why can the router not resolve the host names on the machines on the 10.10.2.0 network and what is "BMC*dhcp"?

Resolve from what? If the client doesn't present a host name or if they are not defined in dd-wrt's host file how could dd-wrt then display their names?

BMC*dhcp is likely a host name but you ought to know yourself which clients you have on your net, can't be that difficult to figure out who the client is.

I don't know how either but ddwrt is getting the hostnames of the machines on the 192.168.2.0 network, but not on the 10.10.2.0 network that I just setup. In one case, I have a laptop wired to the 10, and wireless to the 192 and it gets the hostname on the wireless but not on the wired.

I just figured there'd be a simple explanation.

BMC*dhcp is definitely not here, must be something internal to the router? BMC as in Broadcom?

No, it is not internal to the router it is an external client.
If it is a wireless client then you will also see it under the Status/Wireless tab, if it is a wired client then you can easily find out by disconnecting all your lan port cables and reconnect them one by one while checking which clients appear in the Status/Lan page.

It was one of my servers, not sure how but when I turn the server off the router doesn't report this IP. Thanks for the help.
