I didn't quite see the need to create the host table for the little lab network with a data server talking to a recording device, because I thought the switch in between would be enough. Anyway I decided to do some digging.
Linux
Obviously the host table is located in the “/etc/hosts” file, containg IP addresses and hostnames. Here's a sample below:
$ cat /etc/hosts
# Table of IP addresses and host names
127.0.0.1 localhost
192.168.1.2 myserver aliasname anotheralias
Windows
Windows 95/98/Me c:\windows\hosts
Windows NT/2000/XP Pro c:\winnt\system32\drivers\etc\hosts
Windows XP Home c:\windows\system32\drivers\etc\hosts
The host table is useful when you have a small number of servers in the group and you want to use some alias, and/ or there is no DNS or connection to the internet. The host table simple converts IP addresses to host names and the reverse.
It gets tricky when the host table is long and it gets messy.
