That’s interesting. I’ll ask around. It’s surprising to me, because every time in the past that I needed an OID, we allocated it out of 1.3.6.1.4.1.2620.x.

http://www.alvestrand.no/objectid/1.3.6.1.4.1.2620.html

I didn’t think we’d want 1.3.6.1.4.1.2620.4.1, so I didn’t speak up.

I’ll find out where this 1.3.114 came from, and why we’re not using it.
