Using the Same IP Address as the Primary Network Interface

This addressing scheme is appropriate for point-to-point links only. In this scheme, you specify the addresses of the primary network interface for each endpoint. (See Chapter 1, Overview of Network Administration, for more information about the primary network interface.) These endpoints might be:

• Two standalone machines communicating over the PPP link (if they have existing IP addresses)

• Two network endpoints communicating over the PPP link

• Remote host connecting to a network dial-in server through a point-to-point link

• Dial-in server connecting to remote hosts through a dynamically allocated point-to-point link

When you edit the /etc/inet/hosts file on a local endpoint, supply the IP address of its primary network interface and host name and the IP address of the peer host on the other end of the link.
