So I was looking into getting port forwarding set up and I realized just how closed-off the internet has gotten since the early days. It's concerning. It used to be you would buy your own router and connect it to the internet, and that router would control port-forwarding and what-have-you.
Now, your ISP provides your router, which runs their firmware, which (in my case) doesn't even have the option to enable port forwarding.
It gets worse - because ISPs are choosing NATs over IPv6, so even if you install a custom firmware on your router without it getting blacklisted by your ISP, you still can't expose your server to the internet because the NAT refuses to forward traffic your way. They even devise special NAT schemes like symmetric NAT to thwart hole punching.
Basically this all means that I have to purchase my web hosting separately. Or relay all the traffic through an unnecessary third party, introducing a point of failure.
It's frustrating.
I like to control my stuff. I don't like to depend on other people or be in a position where I have to trust someone not to fuck with my shit. Like, if the only thing outside my apartment that mattered to my website was a DNS record, I'd be really happy with that.
Edit: TIL ISPs in the US don't have NATs
Edit 2: OMG so much advice. My knowledge about computers is SO clearly outdated, I have a lot of things to read up on.
Edit 3: There's definitely a CGNAT involved since the WAN ip in the router config is not the same as the one I get when I use a website that echos my IP address. Far as I can tell ~~my devices don't get unique IPv6 addresses either~~. (funnily enough, if I check my IP address on my phone using roaming data, there's no IPv6 address at all). It's a router/modem combo, at least I think since there's only one device in my apartment (maybe there's a modem managing the whole complex or something?). And it doesn't have a bridge mode, except for OTT. Might try plugging my own router into it, but it feels like a waste of time and money from what I'm seeing. Probably best to just host services over a VPN or smth.
Edit 4: Devices do get unique IPv6 addresses, but it's moot since I can't do anything but ping them. I guess it wouldn't be port forwarding but something else that I would have to do that my router doesn't support
What ISP do you have and what country are you in? I have Comcast in the US and do not have this issue even though they are a big and shitty ISP (I even use their modem, but I do have my own router which I HIGHLY suggest).
The older and shittier the ISP the more blocks of IPV4 addresses they have. They have blocks from when they were given out willy nilly.
New ISPs, the ones that compete and bring the prices down have to buy addresses and that costs money and is a cost bigger and older ISPs do not have.
This is a case for regulation - either mandating a move to V6 or mandating the release of stockpiled v4 addresses. ISPs will not do that on their own, the addresses can currently be sold for lots of money.
The US and other western countries don't really feel the pressure of IPv4 scarcity yet. ISPs in other countries typically uses CGNAT or IPv6. Some even give you a routable IPv4 but may randomly replaced it with an ip behind their CGNAT when the lease is expired, giving you false sense of hope.
IPv4 address depletion isn't really the ISP's fault. It's a shitty solution to a shitty situation, to be sure, but it's either that or employing rationing strategies to stretch the remaining supply of IPv4 addresses.
Or just use IPv6...
Many ISPs in Denmark actually charge you 30-40 DKK (4-7 USD) extra for the 'luxury' of IPv6, which is the same that they charge for publicly routable IPv4 (of course). I found that quite infuriating, so I searched around and found one that had public IPv4 and IPv6 included in the price. A little more expensive all in all, but I just hated the concept of IPv6 being an "extra" in 2023.
Holy fuck, IPv6 is specifically designed to be non scarce and they have the gall to charge extra for it. Gross
Exactly! I wrote the same thing to them when that became clear.
