[Dnsmasq-discuss] Method to get Dnsmasq serve address of a host from interface address

[0zl]

Well, it seems like dnsmasq just ignores addresses with /32s. I see in 
src/network.c for some reason if an interface has 255.255.255.255 it 
just skips it (line 363)?

This might possibly the cause for the issue, I'm not sure if this is 
intentional or some sort of bug.

Thanks again and sorry for the noise!
