Does anyone know what the red striped sections are? Hovering them only yields is excluded from scanning , but that doesn’t say much

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 hoo-boy, it was a shock to see who owned that IP range, Army Information Systems Centre. I chalked it up to them maybe running a torrent tracker or something, or was the DoD in my PC?

The map also does a good job showing why we need to do away with multicast/class E and reuse the address space.

and what, earn 5 more years till we have the same problem?

That's a problem for the people in 5 years

Surely something from https://en.wikipedia.org/wiki/Reserved_IP_addresses could be repurposed?

240/4 can be hijacked/used as private IP space currently by a lot of devices. I think Windows might be the hold out. But for internal routing and IoT it’s very useful. Can never be used as publicly routable space. I’d like to see it added to the official list of private space alongside RFC1918.

https://www.ietf.org/archive/id/draft-schoen-intarea-unicast... is a nice historical overview of 240/4

I 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.

See "List of assigned /8 blocks to commercial organizations" at: https://en.wikipedia.org/wiki/List_of_assigned_/8_IPv4_addre...

Mercedes-Benz isn't the only corporation with its own /8 block - although it is the only non-US one; and it's a pretty small exclusive list, only six in total. I guess someone at Mercedes-Benz just happened to hear about this Internet thing relatively early (53.0.0.0/8 was registered Oct 1993 according to Wikipedia - the relevant European authority, RIPE NCC, was only founded in Apr 1992), and/or happened to have a buddy at IANA / RIPE NCC, and the rest is history.

At this point, time would be better spent moving to IPv6, don't you think?

I'd guess they bought a whole block early on because they could and it wasn't too expensive yet. I wonder if they could be compelled to auction it off. But they might be using it a lot internally. (a lot of guesswork in this comment, I don't know anything lol)

In the early days no money changed hands at all. You just asked for a block and got one.

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:
