Even though with bad configuration they can cause a lot of confusion and
disruption it can be done safely. My router is handing out IPs using dhcp,
but cannot parse the PXE options. On my MythTV backend I have setup a dhcp
server that does not assign IPs except for a list of mac addresses it knows.
The following works for me (obfuscated domainnames and IPs):

<- snip ->

The list of host declarations can be expanded as needed. I would not
reccommend this setup as running two instances can easily cause trouble, but
it works for me and I can safely have my Mythbackend go offline while
letting my laptop go online based on the info provided by the router's dhcp
server.

I am surprised that this works. How do you prevent the router from assigning
an IP before your backend does? Or has it just been the luck of the draw,
and you have been lucky a lot?

I am intrigued by the fact that your router does not support DNSMasq. What
do you have and what firmware?
