DHCP is not a great choice in a mobile environment and also not when

Why can't a mobile system have a locally valid DHCP record (+/- the

of a wireless link)? For that matter, why couldn't a DHCP server have
real-time triangulation data, if it exists at all?
Do you mean more complex than can be expressed by RFC 4776 and RFC
3825 together?
If you look at DOCSIS cable, a single head end can subtend a huge amount
of cable in a single bridged domain. I seem to recall that in a rural
Canadian
MSO I worked with it was 10's if not 100's of miles. I have no clue how
accurate GEOPRIV tries to be, but it sure seems that if the location of the
headend/dhcp relay is only piece of information you have, your accuracy is
going to be pretty lousy in many cases. If this information is intended for
first responders, it seems that all you're doing is pointing to the
right haystack
to start searching for the needle.
