Managing addresses and ports for HTTP Server

This topic provides information about how to manage addresses and ports for your IBM® HTTP Server for i with the IBM Web Administration for i interface.

About this task

Most browsers make HTTP requests on ports 80 and 443 by default. Typically, the default configuration option is for servers to listen on all IP addresses on port 80. Multiple servers cannot listen on the same port and IP numbers. Multiple servers may listen on the same IP address, but require a unique port, or they may listen on the same port, but require a unique IP address. If you want each server to listen on port 80, then you should configure each server to listen on a specific unique IP address. In addition, if you add another Web server product such as Lotus®Domino® on the same IBM i server, it cannot listen on the same IP address and the same port as the HTTP Server.

You can change the IP address or port for your server by doing the following:
