It is really good for blocking whole Chinese & LLM scraper ASNs!
why u have to mention Chinese?
Anyone who has operated a public webserver knows that the vast majority of the rabid, robots.txt ignoring hyperscrapers are from Chinese autonomous systems

#43I find the map the most interesting map: https://map.bgp.tools/ And did not know Mercedes holds such a large block (53.0.0.0/8), and it appears to be mostly dark or unused.
The XKCD Map of the Internet is good too (2006): https://www.xkcd.com/195/

The map also does a good job showing why we need to do away with multicast/class E and reuse the address space.
At this point, time would be better spent moving to IPv6, don't you think?
We have been trying to deploy IPv6 for 20 years now. This would be comparatively easier and buy us another 20 years to finish v6 deployment.

They're part of AS749, which is US Department of Defense IP space that appears to be unused and which, based on public statements made by the Pentagon, might just be safely parked or might be part of a network scanning observatory [1]. Either way, scanning that space is probably a waste of bandwidth. [1] https://blog.benjojo.co.uk/post/ip-address-squatting
Maybe a bit off topic, but years ago I had a home linux server, used for usenet/torrenting. I was just poking about on it one day and ran some variation of netstat and could see a connection with a 6.x.x.x range IP address, which stood out. I didn't know a whole lot about networking at the time (still don't), couldn't say if I had misinterpreted what I saw in the netstat output. But it stood out so I looked it up and…
Service providers (especially mobile ones) often squat on large, unused IP blocks (of which the DoD has plenty of), especially at peak capacity. I suspect this is what occurred here.

And 50% of the internet traffic is IPv6. The proposal here is to introduce a separate (arguably harder) change which would start at 0% support again. Beyond that, it'd just be a temporary fix.
Just 240/4 allowed specifically for private network use (like the 10/8 range)... that I could get behind though. This would still exclude 255.255.255.255/32 of course.

A ton of old equipment would need to be upgraded to use 240/4 for IPv4 unicast. We'd run into weird issues where it works for some people and not others. I'm not convinced. If this was done 25 years ago, maybe.

Surely something from https://en.wikipedia.org/wiki/Reserved_IP_addresses could be repurposed?
No. It will take 10 years for everyone to update their router configuration/software to treat the new “formely-reserved” addresses as global unicast. There’s no point in doing that whatsoever. That effort would be spent much better by adopting IPv6.

Not sure why you'd need more than 10/8, but I suppose it looks even cooler too those who know and find such things cool. Does Windoze prevent you from using certain IPv4 addresses?
> Not sure why you'd need more than 10/8 Large organizations have moved to IPv6 because they, and everyone else, are using 10/8, and so when mergers and acquisitions happen trying to connect the networks together becomes a nightmare. See this talk from Wells Fargo as an example: * https://www.youtube.com/watch?v=EzTWjNUb4H4
The pain of merging acquired company networks cannot be overstated!
IPv6 can help, but in my experience there's just soo much old IPv4 tech that no one is prepared to migrate to IPv6.

Just a fascinating map. Like looking into Neuromancer’s cyberspace.
Is there a legend of what the different colors mean?
