Firmware? As usually, you can use the command man nsswitch.conf, man resolv.conf and man resolvconf for more information. Some legacy software/IP stacks may have problems with it.

To subnet this network, you will have to steal bits from the third octet. I want to POrtforward so is PortForward Free? Usually it tries the /etc/hosts file first for static local names, then avahi mDNS for dynamic local names and then a DNS domain name resovler to get a name from internet.
