What is the <names> command used for in the PIX firewall?

I noticed that 2 of our PIX firewalls have a difference in the configuration; one has the "names" command, and the other has "no names". What is this used for?

Re: What is the <names> command used for in the PIX firewall?

Use the name command to identify a host by a text name. The names you define become like a host table local to the PIX Firewall. Because there is no connection to DNS or /etc/hosts on UNIX servers, use of this command is a mixed blessing—it makes configurations much more readable but introduces another level of abstraction to administer; not only do you have to add and delete IP addresses to your configuration as you do now, but with this command, you need to ensure that the host names either match existing names or you have a map to list the differences.

To disable displaying name values, use the no names command.
