With an address starting with 192.168 you are on a local network, probably behind a firewall, so there really isn't a DNS translation happening. 192.168 addresses are non-routable - they never leave your building. It is going to depend on what kind of switch or gateway you are using. I suggest you start with it's manual.
Yes, I'm on a local network. The question remains: how does the network know that 192.168.0.100 is "KITCHEN"? There has to be translation going on somewhere, I would think. It's a DLINK 614+ router. Thanks.
