[SNMP4J] IPv6 address in varbind is represented as 0.0.0.0 on receiver machine

[Frank Fock]

Hi Vijay,

I do not know which type the object
1.3.6.1.4.1.9.2.9.3.1.1.66.1
has by its MIB specification, however,
I guess, it is IpAddress. The syntax
IpAddress is IPv4 *only*. If you
use a IPv6 address to set it, it
will be undefined what address is used
on the wire. Most likely, it is the
default (0.0.0.0) or the IPv4 portion
of the IPv6 address or something
completely different.

Regards,
Frank
