The Internet Protocol address table (IPT) is a TCP/IP control block structure that contains information about each TCP/IP offload device interface address and is located in main storage. Each TCP/IP offload device may define one or more interfaces with the Internet or IP addresses. One or more IPT entries are obtained whenever TCP/IP support connects a TCP/IP offload device to the TPF system. TCP/IP support saves each address in the IPT so that it can be obtained when a socket application issues a bind API function call. When a socket application issues a bind for a specific IP address, TCP/IP support compares the IP address coded by the application with the one saved in the IPT to ensure that it is valid.
Each Internet Protocol (IP) entry contains information such as IP address, adapter ID, and path ID.
An IP entry is returned to the system when its associated TCP/IP offload device is disconnected from the system.
Each processor in the TPF system has its own unique IPT. Therefore, the IPT contents are not necessarily consistent across all of the processors in a loosely coupled TPF system.
There are no related control block structures for the Internet Protocol address table (IPT).
