RE: what's my IP addr on AS400 -- using DHCP

Maintaining routes table is a basic part of ANY TCP/IP stack
implementation. These should not be confused with routes across the
network which are indeed responsibilty of routers.
Look at ROUTE command on any Windows or Unix system and will show you
essentially the same information.

When configured carefully it never creates any problems. Of course,
messy configuration with conflicting routes will.

    Best regards,

          Alexei
