Side note, but where are we going to do development? I think we should get our work in a feature
branch as soon as possible so we can all contribute to the development.

Sheng, can you push any work you have done to a branch? I'll check and see if I need to commit
any of my changes then.

No, dnsmasq looked like it could...

So, in my lab env I've made a few changes to the server and UI to allow multiple IP blocks
in basic network (haven't tried in advanced yet), then additionally I'm passing a netmask
down to the agent, then that's passed through to, and then into,
which I've updated to support dhcpd.  The one thing I wanted to do but haven't is to update to support both dnsmasq as well as dhcpd.

Note: this was done in-house without community involvement as I didn't expect general interest
in this, but I'm happy to use experience gained to write similar support in the ASF tree.
