Where to purchase a subnet?

Hello, I am wondering where I can buy a /24 subnet. I am looking into hosting some private proxies. I have a server and everything but I am trying to figure out where to buy a clean /24.

Easily check the provider offer 250 proxies at one order, such as proxies for Ticketmaster.

Besides checking with existing providers, you can also have a look at datacenter/cloud providers. They offer IPs and sometimes whole subnets.

Unfortunately, there isn't a single place where you find them, you will need to check and contact multiple potential sources.
