Are there applications that require them? Here are three reasons: 1) I have not studied the causes and thus cannot explain it, but some Telnet hosts seem to take about 10 times longer (some 30 seconds as opposed to 2 to 3 seconds) to give me a logon prompt if I use a dynamic rather than a static address. 2) I prefer to use a static address for our mail servers, so I can address them directly without needing to go through address resolution. 3) Also, some network bureaucrats apparently believe they can collect "better" statistics if they can match individual users with a specific IP address.

Your hosts are probably running unix. Some unix systems seem to want to do a reverse translation on the ip address when you connect before they will give the login prompt. (For example, our old Pyramid did this.) It didn't care if the remote user had a static or dynamic address, if it wasn't in the DNS, it waited. I never figured out why unix would do such a silly thing, but there were so many other more serious things to worry about with it, that I didn't bother with this one. Alan
