The file /var/ipcop/dhcp/dnsmasq.local allows Administrators to add their own options to the DHCP server.

Refer to the dnsmasq manual for information.

For example, to provide a stable address to a machine with two interfaces (e.g. a laptop with both wired and wireless interfaces) add this line:

dhcp-host=XX:XX:XX:XX:XX:XX,YY:YY:YY:YY:YY:YY,192.168.3.200

Or, to link to a file containing a list of domains you'd like to block, such as a collection of banner ad sites, add this line to dnsmasq.local:

conf-file=/path-to-your/blocklist

That blocklist file should contain a list of addresses in this format:

address=/domain-name/127.0.0.1
address=/another-domain-name/127.0.0.1
...

Restart the DHCP server via the web interface or restartdhcp after you modify dnsmasq.local so your changes propagate to the network.
