Static and Dynamic IP Interfaces

Point-to-point IP interfaces may be static or dynamic:

• Static IP interfaces are associated with a single asynchronous device (modem). Clients that call this device are always given the same pair of IP addresses. Static IP interfaces are commonly used when a small, or predictable, number of clients connect to the server.

• Dynamic IP interfaces are associated with the available asynchronous devices (modems) on demand. Clients that connect to the server may be allocated any IP address from the pool, regardless of which device they call. Dynamic IP interfaces are commonly used when a large, or unpredictable, number of clients connect to the server.

See "Generic Internet Server Configuration" for a detailed example of an Internet server configuration that uses dynamic IP address allocation with dynamic IP interfaces.
