The Address Translation Group

Implementation of the Address Translation group is mandatory for all systems. Note however that
this group is deprecated by MIB-II. That is, it is being included solely for compatibility with MIB-I
nodes, and will most likely be excluded from MIB-III nodes. From MIB-II and onwards, each
network protocol group contains its own address translation tables.

Address Translation Table

The Address Translation group contains one table which is the union across all interfaces of the
translation tables for converting a NetworkAddress (for example, an IP address) into a
subnetwork-specific address. For lack of a better term, this document refers to such a
subnetwork-specific address as a physical address.
Examples of such translation tables are: for broadcast media where ARP is in use, the translation
table is equivalent to the ARP cache; or, on an X.25 network where non-algorithmic translation to
X.121 addresses is required, the translation table contains the NetworkAddress to X.121 address
equivalences.

Description The Address Translation tables contain the NetworkAddress to physical address equivalences.
Some interfaces do not use translation tables for determining address equivalences (for example,
DDN-X.25 has an algorithmic method); if all interfaces are of this type, then the Address
Translation table is empty, and therefore has zero entries.
