I just recently stumbled upon FreeDNS. It's a place to get a free subdomain for your project. But not just!

The site FreeDNS began in 2001 because founder Joshua Anderson wanted to have fun with his domain hobby. He wanted to create a safe environment where other programmers could share domain names with one another at no cost, starting with friends.

There are fun domain names, like: crabdance.com, raspberryip.com, 0000000000000000000000.com. In total, more than 44_000+ domains to choose from!

Maybe, I'll "donate" a domain or two in the future.
