Yes. My ISP will rent me a single IPv4 address for $10 per month. Or I can use DHCP, where my IPv4 address can change at their whim.

> Yes. My ISP will rent me a single IPv4 address for $10 per month. At that price point you can get a small vm, but if you have a dedicated server you want to use on-prem, 10$/mo seems like a reasonable price. > Or I can use DHCP, where my IPv4 address can change at their whim. Check the dhcp.lease to make sure, I used to think that, then I looked at the dhcp lease and the IP was being reserved for up to 48 hours of disconnection. I went years without it ever being released. Phone operators won't necessarily transmit this information to you, the true ISP operator is the DHCP server. Not only is it more knowledgeable, but DHCPd has no incentive to upsell you, just provides you with what it is configured to. I'd even go as far as checking if you can send parameters during the dhcp lease request, maybe you can request a longer lease on the IP. There's a right way to do things, it's not trivial to discern from the wrong way to do it, but once you see it, you notice that you lose almost nothing, it's not like the 'wrong' way is simpler, it's just 'wronger', all the way through. I guess the reason they persist is sunk-cost fallacy, the businesses and people that went with NAT then developed STUN, and then they developed ICE, and then they develop Tailscale, every time you need to invent a bigger spade to dig you out of the hole and into a deeper one. Or you can just use IPv4. But aghast, you have to pay 10$/month (or learn DHCP)

  > or learn DHCP There's nothing to learn here in the end. Its just rules imposed by the ISP. I've had places where the leases expired weekly, and I'd often get a different public IP address when renewed. No amount of learning will change this. If I want out of that, I'd have to pay extra money every month. I've also had ISPs where I've had the same IPv4 address for years. So long as I was online around the time of the lease renewal, I was pretty much guaranteed to get the same IP. YMMV. > At that price point you can get a small vm, but if you have a dedicated server you want to use on-prem, 10$/mo seems like a reasonable price. So I can spend $10/mo for each IP address I want, or I can just use IPv6 where my ISP gives me 295,147,905,179,352,825,856 IP addresses (a /60) by default for free. Hmm...which to choose...

    An ISP should be giving you a /56. If they are giving you a /60 that the sign of a terrible ISP anyway.

      No argument from me here on the /56 vs a /60, I play the cards I'm dealt. AT&T being the same shitbags they've always been. But its multi-gigabit fiber from them or questionable DOCSIS from Spectrum, and I've never met an honest Spectrum representative. I refuse to do business with them after all the fraud they've given me over the years. In the end its still a bajillion-ish IPv6 addresses I have to play with versus the one-ish I have with IPv4.

So change ISP. Your isp is making a fortune from you as part of price segregation, nothing to do with demand.
