There is much more to utilizing DNS itself, but we have given you the tools to build a DNS server. You can now use this server as a spare, a test bed for configurations or anything else you can think of. A common use of DNS within a network is to refer to devices specific to our network, such as file servers. We can also put in entries for IP printers, individual workstations or anything that has an IP address. It is a lot easier to remember "3rdfloorprinter" than "172.16.23.192." It is also handy to have people hitting your email server by its internal address rather than having to go outside the network only for it to come back in.
