Also if you want a domain but dont care about the actual address, a .xyz domain composed entirely of numbers with less than 10 digits is $1-2 + same as renewal fee per year. $1.22 for me on porkbun
Just be sure to redact the whois information bc you will get a call from scammers trying to get you to register your domain on some "internet map" for a small fee acting as if its some step in your setup process you havent done yet
