It would be better to if we could fix inet:ip-address in RFC 6991 BIS to not include the zone similar to what was done in the MIB (RFC 4001). However, we're getting the passive aggressive treatment on this point.

[as wg-member]

I think we should do the right thing in our (LSR) modules no matter what, again, what harm does it do to get it right in the modules under LSR WGs direct control?

The netmod change is a much larger action with a large blast radius (not saying it's wrong), and perhaps most importantly is also outside of LSR WG control. :)

Thanks,
