A
ifSpecific (1.3.6.1.2.1.2.2.1.22)
A reference to MIB definitions specific to the particular media being used to realize 
the interface. For example, if the interface is realized by an Ethernet, then the 
value of this object refers to a document that defines objects specific to Ethernet. 
If this information is not present, its value should be set to the OBJECT IDENTI-
FIER { 0 0 }, which is a syntactically valid object identifier, and any conformant 
implementation of ASN.1 (Abstract Syntax Notation) and BER must be able to 
generate and recognize this value.

The Address Translation Group
Implementation of the Address Translation group is mandatory for all systems. 
However, 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.
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.
