Reclaiming IPv4 Class E's 240.0.0.0/4

The difference between a /48 (like my residential handoff) and a /64 (like some people get) is the same as a difference between blocking a single /32 ipv4 address and blocking an entire /16 - which is a very large allocation

If you wanted to block me, you'd have to block the whole /48. If you blocked a /48, you could be blocking 64,000 people.

I meant IPv4 - one IP might represent thousands of users.

Looks like crote brought the issue up in a sibling thread.

I haven't experienced such congested CGNATs. And assuming there are people who are under such CGNATs, they are probably used to being rate limited all the time.
