Right, some hosts may, but not all. Especially those that don't do
DHCP for 3GPP.

What about the laptops with built-in 3G/4G or using UE as a modem?

I don't know much about how that interface usually goes (PPP or
DHCP+Ethernet), but sure laptops could be modified e.g. by driver updates(?).
But then I don't know about laptop OS'es capability for doing DHCPv4 on-demand
(I would expect the laptop OS'es would rather try to keep IPv4 address
allocated all the time).

There's traditional tethering vs the cpe approach, at the point where the handset simply acts a a router, maintenance of the pdp context(s) and indeed the whole air interface is solely at the discretion of the handset/router, and the PC is invisble in that equation.


We should make this distinction (laptops, UE-only). Laptop OS's do support
DHCP obviously.

Yes, but this is *may* per 3GPP TS 23.401. Your draft should be more
explicit
in telling that the percentage of host population that actually
implements the
*may* part is unknown for time being.

I would rather say that DHCP is optional but a provider may require it
to be used.

Right, consumers often has this power over producers..
