When a computer configured with more than one IP address, it is referred to as a multihomied system. Multihoming is supported in two different ways:
  1. Multiple network adapter or media types per physical network. The network adapters can be for similar or dissimilar network. For example, a host with one ethernet and one token ring adapter installed, each linked to a separate network, requires IP addresses to be bound to both adapter. There are no restrictions other than hardware.
  2. Multiple IP addresses per network adapter. A computer can access multiple subnets that are logically separated, but bound to a single network adapter, such a configuration might be used in an environment where a host requires access to different divisions of a corporation network that are separated by different subnets.
