What do you mean by "rregistering [a] manager" ?

There are two situations where the agent might specify a network address:

  -  acceptable sources for community-based requests
          (note that SNMPv3 access control is source-independent)

  -  notification destinations

Both of these can be configured via the snmpd.conf file, and this does
include support for IPv6 addresses.  See the snmpd.conf(5) man page
for details.

The (community,source) to security name mapping is not covered by any
MIB module - it's purely handled by the config settings.
   (There is a standard community MIB, but it doesn't take any account
of where the request comes from)

Notification destinations are handled by the Target MIB.

The SNMP-TARGET-MIB is not restricted to IPv4.
The target address is specified by the pair of objects
   (snmpTargetAddrTDomain, snmpTargetAddrTAddress)

These can handle both IPv4 addresses (using transportDomainUdpIpv4),
IPv6 addresses (using transportDomainUdpIpv6), as well as a series of
other alternatives.   See TRANSPORT-ADDRESS-MIB for a possible list.
