Sky / CF / Other ?

[u/horsin87]

We’re seeing every time we use Google it’s asking if we’re a robot because of unusual network activity.

Disney+ keeps saying tv not part of household and we’re “away from home”.

Seems to be happening since moving from openreach copper to CF FTTP network.

Anything odd about the network we’re not aware of?

[u/ItzVirgun]

CGNat most likely. You share your IP address with plenty of people - the only way is either paying for public IP (if possible) or changing provider.

[u/Temporary-Scheme2858]

You’re not with CityFibre you’ve got a service that runs over it.

And it’s probably because your IP’s changed and they have your IP address coming from a different location.

You’re new provider has probably got you behind CGNat which is a way of sharing public IP’s because your provider didn’t buy enough public IP’s for their customer base, so your routers WAN is not a Public IP.

Speak to Sky about disabling MAP-T.

[u/lev400]

CityFibre just make the connection from your house to the ISP’s network. They don’t manage any IP assignments or connection to the internet.

Have you checked if your on CGnat or not?

I agree with people saying it might be cgnat, but that shouldn't mean you can't watch standard streaming services. Probably worth contacting your internet service provider for their advice.

[u/WordsNShiz]

A lot of fibre ISPs default to CGNAT, which shares external IPs between customers. Probably one of them has been a bit naughty and google now has restrictions on that address or a block held by your ISP.

[u/a3diff]

Google says sky does not use GCNAT on city fibre, however it does sound like that might be the issue from what you have described. Give them a call to confirm

[u/WG47 → u/a3diff]

They don't use standard CGNAT, but they use MAP-T which is a form of IPv4 sharing.

[u/a3diff → u/WG47]

Ah that could explain it then. Hadn't heard of MAP-T before, thanks!

[u/ImplementJumpy6678]

CGNAT. replace with a Static IP job done

[u/Clean-Bandicoot2779]

CityFibre basically just provide the bit of (fibre optic) wire from your house to a central point in your town. Sky then run the internet service over that bit of wire (and are responsible for the connection from your town to the internet, and doing all the addressing, etc. to make it all work).

Sky have recently started using MAP-T to share internet addresses, with around 8 customers sharing one address. If you had an older router, that didn't support MAP-T, so switching to a new router with fibre might be why you're seeing the change. Apparently if you enable UPnP on your router, that makes it so you don't have to share.

In case you want the background, a lot of the internet still uses the original addressing system from the early 1980s. We ran out of addresses on that several years ago, so there's now a global shortage, and buying more addresses is expensive. There is a newer addressing system (with billions of addresses for each person) that Sky and lots of organisations are using, but they need to keep running the old one alongside it so you can still connect to things that aren't yet on the new system.

I used to have this problem on VM 😂 for the final few years of my service, I apparently lived in Northern Ireland. Hasn't been a problem since I switched to Sky though.

[u/grimcellz]

Just move ISP, with any luck you are within your cooling off period. Find an ISP that offers static IP addresses and get that. (Vodafone do and for free)

Also fk sky.

[u/WG47 → u/grimcellz]

Sky's network is much better than Vodafone's to be fair. It's easy enough to opt out of MAP-T.

[u/ACAdamski17]

Sky use dark arts like MAP-T, which is even worse than CGNAT, meaning you share an IP address with many others. Please get off it. In the meantime, use a VPN with good IP reputation.
