It is very trivial (with each OS) to give the host a specific name. Naming schemes are very different and a matter of admin's taste. Give them names you you quickly know which one is which physically which host. You can setup a DHCP server which gives each hosts it's IP more or less dynamically. Or if you prefer to be sure which IP a host has, then set up your local DNS zone with your DNS server. But if we are speaking about a 33 hosts local net, then running your own DNS might be too much and it is ok to have the IP <--> hostname mappings set in each host's /etc/hosts file. Your NAT gateway does not need to run as DNS for your local network to be able to serve as a constant or occasional internet gateway. Using the ISP's DNS server addresses is sufficient. While running your own DNS could improve speed for LAN hosts when browsing and using the internet. Especially helpful can be to run a proxy cache like squid. > What I'm trying to do is set up a small home network to teach myself > some things like networks, firewalls, iptables, etc. and the box I'm > setting up now is many of these functions as possible and as an > Oracle server.
