I could move it to a different block (not within
44.190/16) and set it up so that it’s part of the tunnel/mesh as well if folks think that
will be better?
That should solve the problem for Greg and Brian.
For me it does not matter.
When you do have an external address (which you should have for IPIP, please don't put
a tunnel endpoint on a net-44 address!)
you could also consider to put the external address in the DNS entry as well. Or maybe an
IPv6 address for each of the systems.
