Sure. Which is why it's just part of a conversation, not a boolean filtering question.

I didn't claim it to be a new idea - I asked why we didn't do something simple like that (as the solution) instead of all the expensive complexity of trying to upgrade the entire Internet to IP6 over multiple decades.

I think you have missed that a IP4.4 packet would be a valid IP4 packet. The first 4 octets of the 4.4 address are where IP4 expects them to be. The router at this IP4 address needs to understand IP4.4, but routers before do not. The additi

If a source behind an IP4.4 router sent a packet to an IP4 destination, then yes, the source router would need to apply NAT to the source address. But this is already a standard IP4 router capability, and I think that most connection origin

Thanks for that. As a transition-to-IP6 technology that makes a lot of sense, but I think it required a lot of prerequisite technology and work (i.e. IP6 itself). The hack I described could have been implemented on top of existing IP4 codeb

Happily traverse the existing IP4 Internet, to an IP4.4 aware edge network. The point is that you don't need to modify any IP4 networks between the IP4.4 aware origin and destination routers.

It routes it as an IP4 packet, because it still is a valid IP4 address. Think of it as a way to let a stateless IP4.4 aware NAT router at the edge join two 32-bit networks together. An IP4.4 client could send a packet to a destination in th

I am not a network engineer, but for about 20 years I have wondered why we didn't 'just' do something like: 1. Include an extra 32-bits of address information as an IP options header. Call it an IP4.4 packet. 2. (I think?) IP

I can also tell the difference, as displayed in a rainbow, but if they were next to each other in a data visualisation I think i'd have no chance.

Each of the 8-bit channels is only allowed 16 different values, i.e. needs 4 bits to represent. I think it's reasonable to describe three 4-bit channels as 12-bit colour?

I really like this, but FYI I do struggle to tell the difference between the first and last colour. There are probably others out there with this problem.

> Humans really aren't that good at long-term planning, is one conclusion. I think the problem is long-term co-operation rather than planning. The temptation of short-term gain is always too great for someone.
