The IPv6 Address Translation table used for
mapping from IPv6 addresses to physical addresses.
The IPv6 address translation table contain the
Ipv6Address to `physical' address equivalencies.
Some interfaces do not use translation tables
for determining address equivalencies; if all
interfaces are of this type, then the Address
Translation table is empty, i.e., has zero
entries.
This table is obsoleted by IP-MIB::ipNetToPhysicalTable.
