Huh? With IPv6 you get your own IP address, the ISP doesn't need to know shit about ports. Your address is not behind a NAT anymore, and ports don't need to be forwarded.
Perhaps you mean the ISP set up a firewall that blocks incoming connections? In which case, maybe you can have that firewall disabled? ISP firewalls and "safe browsing" packages are always shit.
To be honest though there might be some aspect to this I don't know.
Honestly, I was there the first time round, when everyone raw dogged the internet on a single modem per PC. I remember Blaster, and talking people through removing it in 60 second bursts as their PCs shut down over and over.
It was carnage. The average user doesn't need open ports on the internet, and they'll only get their elderly machines infected instantly if they did.
Not always possible. In Spain IPv6 adoption is at like 5%. There's literally no ISP that offers it. I don't even know how that 5% got it, maybe special deals.
Yes just had a look, according to Google countrywide it's 10%. Very low, sadly. Neighboring France at 74% IPv6. Interesting to see the difference even with neighbouring countries.
Sure, in the UK we have very strict rules around competition law and broadband access. Here, fibre businesses lay fibre to premises (and are paid to do so). Then, a customer can order from any number of broadband providers, and the company who originally laid the fibre lease that line out at wholesale prices. The broadband operator runs 'over the top' of whoever installed the fibre.
That way, the fibre installer makes money over time, gently and progressively. All broadband companies and smaller 'Alt-Nets' as we call them, have an equal opportunity to a customer base. Finally the customer has the choice to find services matching their needs and price points. Pay a lot get a lot, pay less get less.
I think I have a choice of 6. Names which come to mind are EE, Vodafone, Virgin, Trooli, Cuckoo and Orange.
Meanwhile, in the US, the government paid ISPs for fiber to be ran and they just pocketed it instead.
Now we've got smaller companies running fiber and charging less for synchronous gigabit than you'd pay for copper 500mb down 5mb up, and ISPs are panicking a bit.
All the fiber maps have big empty zones where apartment complexes are, sadly.
Here in Greece, we have three providers, but I don't want to change, since we pay very little money to the one I am in right now in return of slower speeds (5 Mbps download, 0.5 Upload).
move providers? Where, to who? There is currently one provider where i live, soon potentially to be two. Though it's not finalized yet, nor constructed, so for all intents and purposes, it's just the one provider.
As soon as fiber covers the final < 0.5% of my city with fiber (🤞 but I doubt it will happen) I'll switch off of cable. Until then I can use cable with one provider or DSL with another.
