View Full Version : Changing of AS/400 IP address
01-01-1995, 02:00 AM
Hi all, I pose a question to anyone who has gone through an AS/400 physical location move/re-assignment of the IP addresses. Will CA/400 connections resolve the new IP addresses for the 400's provided they (the PC connections) are using the DNS names which will have the new IP address loaded for the named 400's? Thanks!

Jason, If connection type is NS Router, no problem (assuming connection is to the same machine). If connection type is TCP/IP, you have a problem. CA/400 connects via IP address (not DNS name). You have to go in and change each PC's CA/400 connection address and/or HOSTS entry in Windows.

I am not sure that is always true. Ever since we created a DNS entry on the NT server for the AS/400 systems, whenever a new installation of Client Access (Express or V3R2) is done, we enter the system name during connection wizard setup and the IP address is returned based on that system name. It has to be coming from the DNS at that time because we do not add the IP's in the host file on the PC. To verify this I checked my host file, only localhost is present. This will be a major issue for my company, so if any light could be shed on this, please let me know and I'll be very appreciative! Thanks!

My experience is this. When the IP address is changed then the network has to have it changed. Once it is changed then the "systemname" will work. It has been a number of years since I did this but when connecting with TCP/IP I didn't have to change my host files on my system because there wasn't and entry for the AS/400. I believe what happens is that CA will search the pc for the qualified ip address from the name. If found it will use it. If not found then it searches the network. When found it uses the IP address. a way of testing this would be to change the AS/400 IP address and try to ping the system name. If you can ping it you should be okay. but then again I might be wrong (gotta protect myself....hahaha)

Thanks alot for your response Glen, I was thinking along the same lines also (in regards to changing/pinging). Hopefully this will work fine for us, because I don't wanna touch 250 pc's next month!!
