I just had RBI installed via Vodafone, replacing my ADSL that was running at about 2Mbps (line length being the main issue). The RBI is great from a throughput point of view - I can see the cell tower and we get 20Mbps or thereabouts, once we get 4G installed at that site it'll probably be faster.
With the ADSL I was using a dynamic DNS provider, which let me get to my raspberry pi from outside the network and control my heating system. I was happy enough with that, so didn't ask about a static IP address.
It turns out that, so far as I can tell, RBI is using CGNAT. So dynamic DNS providers don't work.
Does anyone know if it's possible to get a static IP on RBI, and if so, what the cost is?
Do I need to move to another provider (e.g. UltimateBroadband)?
I see some suggestion somewhere that moving to IPv6 could work, but it's not clear to me at all that a) it's supported, or b) it actually fixes anything without everyone else in the world also moving to IPv6, and we already know they didn't do that.
