Note that if you are using dnsmasq as plain DHCP server to hand out IPs 
instead of for PXE booting, you will likely already have a 3 second 
delay in most cases while it performs a ping check to see if the IP it 
intends to hand out is really free.
If there is already such existing delay, the patch will not delay things 
further, so things are a little less dramatic than they may seem.

That said, will submit a patch that supports tags for consideration.

Yours sincerely,
