This method is not normally used and is not recommended.
For AS/400 business computing systems in the above network, the full route table
could be:
The default is to route all traffic to the router associated with that subnetwork. No
routing configuration is required within the same subnetwork.
All hosts in the same subnetwork must use the same subnet mask.
Broadcast Addresses
Broadcast addresses are used to address multiple recipients on a network as
opposed to addressing a single recipient, which is done through unicast addresses.
Another type of IP address used for the purpose of sending a message to multiple
nodes on a network is the muliticast address. In the paragraphs that follow,
broadcast addresses are discussed. For more information about IP multicasting,
see “IP Multicasting” on page 91.
While there are several types of broadcast addresses, they can be separated into
two categories: the limited broadcast address and the directed broadcast address.
On each physical network, a limited broadcast address is an internet address that
consists of all 1 bits (255.255.255.255.). A directed broadcast address is an
internet address with a valid network ID and a host ID of all 1 bits. There are
different types of directed broadcast addresses, including network-directed,
subnet-directed, and all-subnets-directed.
