First, consider that the 3  major cell carriers in the usa each have

rfc 1918, not arin, … and we are just talking about customer ip

retail ….

Are you saying mobile terminals must be identified by IP addresses?


Nodes in an ip network require ip addresses. 4G and 5G are ip networks for
both voice and data.

I do not believe it is either technically nor economically feasible to run
a 4g or 5g network without an ip address on the ue.
