Apparently, there exists a website called ipv4[.]games, where you can register HTTP web requests from hosts where you have access to. Once accessed, you can "claim" the requesting #IPv4 address with an #HTTP GET request on /claim?name=<NAME>.
The leaderboard leads the person which claims most addresses of various /8 networks.
It is wild to see partially 6-digit numbers for various /8s claimed by one and the same user.
My guess is: Either they leverage residential proxies, or leverage perhaps mass-spamming on having millions of people world-wide clicking links, or alternatively, leveraging modern software design to do the lookup for them (e.g. website previews on social media, or anti-phishing services that do a lookup, before they forward the mail to you).
No matter what, I am sure that millions of these IP addresses in there can be harvested as #open #proxies
Other than that, I like the idea, and love how gamification leads to some people developing creative ways on making millions of hosts on the Internet access this website. It probably still invites to unsolicited requests from strangers unknowingly participating in the game of a tech-savvy person.
