Hi, Fred:

1)    " ... you will need to replace the existing DNS and DHCP systems...  ":    I am glad that you have touched the next level of considerations. Operating an RAN with one 240/4 netblock, there will be more than enough IP addresses to assign to all client premises. So, the EzIP deployment will operate with static IP address disciplines, negating the fundamental reasons to have DNS and DHCP. That is, transition to running the electronic equivalent of telephony White and Yellow Pages would be what EzIP deployment should rely upon.     

2)    " ... hear the relevant organizations saying that it changes their networking model, ... similar to what has happened with the IPv6 deployment.  ":    Do they recognize that implementing EzIP address plan on CG-NAT changes no network model? So, the perturbation is far less than deploying IPv6.

I did read it. Correct my understanding. 

Your proposal is to replace the IP addressing model and IP (yes, you're using options, but the architecture changed). Do so do, you will need to replace the existing DNS and DHCP systems with a PABX-like model - you need to find a way to let systems address each other. It also replaces firewalls with a model that prevents communication with devices that don't know the PABX port numbers. 

Frankly, I can already hear the relevant organizations saying that it changes their networking model, and it starts a process similar to what has happened with the IPv6 deployment.
