Re: The complete IPv4 address space, mapped

The info, at least for my home ISP, is incorrect. The trust score docks 5 points because I don't have a reverse DNS record on the IP, but I do :-P And the reverse DNS box at the top even correcly reports my rDNS The site says that the trust score was improved because the allocation for my IP is >10 years old, however my ISP didn't exist 10 years ago. The ASN for my ISP is only 5 years old (they brought some IP blocks…

It seems the site basically doesn't do anything for IPv6 :-(

I see the same problem with rDNS. The box at the top correctly reports the DNS name as "forward-confirmed" but I see a -5 points penalty for missing reverse DNS. Tried with various IP addresses, and I observe the same for many (not all).

IP allocations are inaccurate due to all the VPNs, (CG)NATs and proxies spoofing everything now, the whole internet is tangled up like weeds.

That's a reaction to people trying to use IP address as an identifying signal. The reaction is that it's only an identifying signal for normal users, just like all the rest of the signals. Normal people get blocked by Cloudflare. Sophisticated bots never get blocked.

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?

e.g.

E.I. du Pont de Nemours (DuPont) 52.0.0.0/8

Ford Motor Company 19.0.0.0/8 Retained by Ford

Prudential Financial 48.0.0.0/8 Retained and used

like, why does Ford need a /8 to make cars? a /20 of public IPs is more than enough for corporate and virtually all of their dealerships

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?

These databases don't seem to be too accurate or in agreement. I've tried to use them To block Russia, china, and a few others which has been a great help in server load but when I do a random check on someone scanning me I still get addresses in Russia and china. There's also the issue of countries leasing or selling blocks of addresses so I'll look at an address that's supposed to be in Africa but the traceroute sa…

I'm actually the person who created the website and yes, geo location means nothing with the bulk of the IP space.

I'm actually the person who created the website. Of course I used AI. Yes the website is displaying inaccurate information but this was due to my attention moving to collecting and retaining accurate data (a lot harder than most of you'd think). Given the scale of the site and infrastructure behind it there's been a lot of trial and error. https://worldip.io/about if you'd care to read more.

That data collection is about 90% solid right now, once I have it 100% I'll begin updating the frontend to read from the proper tables (currently displaying a lot of stale data). Keep checking back on the site and you'll see those changes.

This is why the website is completely free, no account or pay gates. I do plan to offer as a SaaS in time (whoever commented about batch files, I'll be offering those as well), but again this won't be done until I'm certain the captured data is 100% correct.

Thank you to those of you who gave useful feedback.

You just listed companies that have one /8 not multiple /8s.

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.

I can't find one /8 that is assigned to boeing. I think your idea of IP allocation is very outdated.

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 somet…

Yes, currently 12 POP's. See worldip.io/infrastructure
