I don't know 2.9BSD's time frame (and did not look it up) so I can't say
one way or the other.
Based on your response I'm going to assume that it's not possible.
I kinda doubt it has good NCP support: it was released in November of 1983.

I'd have to go back and look, but I think I have read about an NCP and
IP speaking host in the last few months. It may have been related to
MULTICS.
The idea is that it might be simpler to speak TCP/IP to such a machine
and then connect from it to 2.9BSD, if 2.9BSD supported NCP.
If the OPs goal is to get network connectivity on an 18-bit PDP, then
that might be another option that doesn't require shoehorning TCP/IP
into said PDP.
I'd get it running in simh, then move to real hardware. It's going to take a lot of elbow grease to make that work, I think. But I haven't looked in detail at things.
Ultrix-11 is of similar vintage, and similar functionality and does boot on the 18-bit 11's.
