IP addresses

penfold — Sat, 10 Jun 2023 17:18:53 GMT

Does anyone know if Plusnet are using CG NAT. I can't find anything in search. Reason I ask is I'm having some issues with on-demand content from sky, and they think it's down to this, with users effectively sharing ipv4 addresses.
Also I used to have a static IP, a holdover from broadband PAYG.( Yes I've been around that long)😊. I don't appear to have this anymore, but don't recall ever being told it was being removed, unless it was automatically done during a product move, as I'm now on fibre.

@penfold AFAIK, Plusnet do not use CGNAT - it usually only used by mobile networks, and I suspect SKY are trying to fob you off.

Can't help with the static query - sorry. Just a thought - what are the first three octets of your address?

Thanks. They are 80.2
They also told me to change from Google DNS to plusnets, what difference that would make is anyone's guess

The easiest way to check is to run nslookup on your public ip address.

If the reply is something like 1.0.189.80.dyn.plus.net then it is dynamic

I'm not 100% certain - slightly outside my pay-grade, but that is a dynamic pool, I think. Are you using Google DNS -if so why? - but that is more balderdash.

@MisterW
Completely agree.
I'm using Google DNS, as I always have done. Are plusnets DNS servers better than they used to be. I had issues quite some time ago where they were a bit unresponsive.

@penfold - Plusnet do not use CGNAT and it looks to me like your IP address is static.
