addresses, your server appears as multiple TCP/IP hosts in the same TCP/IP
network (Figure 49).

This scenario can be helpful for backup or to improve performance. However,
there is no dynamic backup or performance balance function.
Your server uses one adapter for TCP/IP to attach to a LAN or WAN network. You
add multiple TCP/IP interfaces. Each of these TCP/IP interfaces includes an
Internet address of different TCP/IP networks. With these multiple Internet
addresses, you participate in different TCP/IP networks (Figure 50).

Imagine a public X.25 network. With this physical network, you can run multiple
TCP/IP networks, for example the company intranet, and connections with
business partners and service providers. For each of these different TCP/IP
networks, your server must configure a unique Internet address.
Running multiple TCP/IP networks within a single local area network (LAN) is
also supported. In most situations, however, one designs a single TCP/IP network
per physical LAN only.
Your server uses more than one adapter for TCP/IP to attach to multiple LAN or
WAN networks. You add multiple TCP/IP interfaces. At least one interface is
assigned to each adapter/line description. Each of these TCP/IP interfaces includes
