2/ is a website I run which lets you compete for control of the IPv4 address space. If you can get a computer connected to the Internet to send an HTTP or HTTPS request to my website, then you can claim that computer's IP.

3/ According to Censys there are 224.2m active IPv4 hosts. Players of the IPv4 Games have claimed 38m of them so far. has claimed 10.8m of those.

4/ They've been sending almost a million claims to my webserver each hour. The service runs on a tiny GCE VM with a SQLite database. I had to fix a bug yesterday that caused checkpoint starvation and the WAL grew to 72gb!

5/ There aren't many Class A subnets that doesn't control. Americans may sleep better at night knowing this hacker hasn't claimed any DoD hosts. To date I'm the only one who's managed to do that.

The web server for IPv4 Games is written in C and you can monitor its health by visiting

@Willrandship Additionally in order to successfully DDOS the service you would have to successfully DDOS Google's network. Many hackers have tried and are still trying. Token buckets block abusive IPs in raw prerouting iptables. Ingress bandwidth is free and unlimited.
