Generation XYZ, the provider of the TLD .xyz, offers a promotion for a class of .xyz domains. For $0.99 a year, you can register any .xyz domain in between 000000.xyz through 999999999.xyz. They call it: the 1.111B class.
Of the 5M scanned domains I discovered around 50K active ones. I linked the full map above so you can explore it yourself.
