This doesn't specifically apply to the ISC DHCPd, but I was hoping someone
else out there might have an answer to this question.

Is there a way to prevent a host machine that has configured an IP address
on their PC from access. On my router I have disabled ARPA, and PROXY-ARP.
The router is a Cisco 7223 uBR. I know that on a normal router, using
ethernet that disabling ARPA will work. However, it appears that using the 
uBR (Cable Modem Terminating System) does not provide the same results.

Also, I understand that the ISC DHCPd software will ping addresses before 
assigning them. Does it report that an address is in use and not
legitimately leased? I could use this in a pinch to track stolen
addresses.

Thanks in advance.
