No. No matter how you cobble it, IPv4 doesn’t have enough addresses to restore proper end to end connectivity.  Owen On Jan 20, 2024, at 07:36, Abraham Y.

I have no difficulty directly reaching a variety of IPv6 hosts from the /48 in my home. However, it’s not like dial-up modem operations in the PSTN in that IP is an inherently connectionless packet switched service while modems were an inherently circuit switched connection oriented service. However, it does work like IPv4 used to work before NAT made everything horrible. Owen On Jan 15, 2024, at 12:20, Abraham Y.
