Thanks for the reply Dave. I'm confused by your answers and will need some
more guidance please.

Initially the requirement given to me was to have our box return both the
IPV6-MIB and IPV6-ICMP-MIB. Thanks to this forum I learned that these were
both obsoleted in 2006. The people making the requirment were fine with just
having IP-MIB return IPv6 information.

This is the part where I get confused. If pass-through scripts only accept
types of “integer, gauge, counter, timeticks, ipaddress, objectid, or string”
then how would I use the InetAddress object binary string to return an IPv6
address in my custom MIB? None of those types seem related to a binary string.
(I use the "string" type for returning regular ASCII string values.)

Similar confusion from me here. The situation with snmptrap seems better
because it can accept arguments with a type of "HEX STRING" or "DECIMAL
STRING". I don't know how to convert an IPv6 address into that format though.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
