Hi Frank,

That's was quick response,

Is it the SNMP4J stack based on the varbind type and data, it decided to
put 0.0.0.0?

To support Ipv6 in varbind, do I need to pick the OID that has type
defined as Ipv6? Can you point me to some examples to generate ipv6
address in varbind?

Basic question, Does SNMP4J has list of supported mibs? 


Thanks and regards,
Vijay

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
