Out of curiosity, how much does it cost for you to run this? Not that I'm willing to pay $10k for my own /24, but I find this super interesting.

I just installed a new FTTH ISP at home and learned the hard way what CG-NAT is, after years of having my own public IP with my previous ISP.

The /24 itself doesn’t cost me anything. I registered it before ARIN existed and it’s considered a “legacy” block. No fees cause I never signed their registration agreement.

I pay about $180/month for a “business internet” cable line. 300 megabits down, 25 up. I also “know a guy” at the ISP who made sure the routing wasn’t going to be an issue.

Yep, I was wondering more about the ongoing costs of "operating" the block. I was reading a superuser.com question [1] about it and it mentions ongoing costs, like transit, BGP routing etc.

This is super interesting! I didn't know this was even possible before I started looking into it.

When I read that right, all the transit and routing seems to be done by his ISP. The superuser response is about what happens when your provider (or in this case, ISP) does not do this.

There are no direct costs there. I pay for the bandwidth. The ISP announces the /24 using their BGP ASN.

There are also cloud providers, like Vultr, that will allow you to do BGP with them. You could then get a network block routed to a VPS, then tunnel it out or whatever.
