Interesting project. With ARIN effectively out of IPv4 space, where do you get IPs from for a new ISP? Does it have to be transferred/purchased from an existing block? I am assuming you are setting up IPv6 as well for your customers, are you deploying some sort of CGNAT?

We've been able to source enough IPv4s for our needs so far, but we don't expect that to last forever. ARIN is cutting off the allocations, but there are still a decent amount available for lease.

The transfer market is still viable. I bought my /24 from https://www.ipv4auctions.com/
