[c-nsp] Correct OID for IPv6?

[chiel]

Hello,

I'm trying to make some graphs to see how much IPv6 traffic we are 
doing. I'm using MIB ipIfStatsHCInOctets.

IPv6 incoming: 1.3.6.1.2.1.4.31.3.1.6.2
IPv6 outgoing: 1.3.6.1.2.1.4.31.3.1.33.2

To see if I do it correctly I also create the graphs for IPv4 from the 
same MIB,

IPv4 incoming: 1.3.6.1.2.1.4.31.3.1.6.1
IPv6 outgoing: 1.3.6.1.2.1.4.31.3.1.33.1

But when comparing them with existing graphs that use 
1.3.6.1.2.1.31.1.1.1.6 (ifHCInOctets) and 1.3.6.1.2.1.31.1.1.1.10 
(ifHCOutOctets) for in and out respectively I don't get the same 
results, there is about a 20% increase.

Can someone clear this up for me? I'm I using the correct OID's?
