I think the issue here is that we are thinking of the use from 2 different ends. You are thinking solely from the router - - - and then your impassioned responses are likely correct. I just spent over 1/2 hour looking at a number of SoCs (3) and microcontrollers (also 3) and I can't find one where I can give it this 'classless' address you're talking about. I am limited to using the quad - - - unless I am using ipv6. Perhaps - - - - how can I run ipv6 inside (on my lan) and communicate out using ONLY ipv4? (Popcorn ready!)
