Hmm it says my ASN has 512 IPv4 addresses, as the guy who filled out the paperwork for that from ARIN and got a /24 (256 addresses) afterwards, I think this has some major bugs.

Oh and it doesn't even properly consume the geofeed information I have published.

I really like the website and respect for supporting IPv6 ;) Are you going to keep scanning the v4 address space to see if meta-data changes? If not the data might go out of date rapidly. I see the site plans to add a paid API. Fair... I'm not too sure if people will buy it when you can probably download text files with much the same data as what's on this site. Though I might be wrong here.

If you wanted to do something genuinely cool you could try to build an algorithmic model of latency between network points on the Internet. Such that it would be possible to estimate latency between any two network paths without sending packets first to measure it. I think I read research somewhere that this is possible and it could have applications in routing, distributed systems, and high performance networking.

It's got that AI slop visual style - you know, the one you get if you ask Claude to make a website.

How accurate is it that the DoD has a handful of class A networks? And WTF do they need them for these days, they aren't actually advertising internal networks on the public internet are they?

An addressing scheme is not the same thing as reachability. And the DOD created the Internet. Why would they force themselves to use private address hacks when there will only ever be up to 256 networks connected?

I can immediately identify it now. it's painfully obvious

Earlier quoted context omitted.

It's also inflated by large companies with dozens of class A networks, but who actually need a total of maybe just a few class C subnets. I once worked for a company with tens of thousands of computers that were using public IP addresses, but they were all completely firewalled, and they used proxies for limited Internet access.

Do you have any examples of large companies that have multiple /8s but can get away with a /21?

Hughes had many class As. Rockwell had a few. McDonnell Douglas had some. Boeing had a few. Boeing eventually acquired all of the above. It's possible that they've divested some of them by now. I haven't worked there for almost 10 years.
