Hi can anyone shed some light on a recent issue. The other day I received 2 separate emails from two different colleagues around the same time. The originating IP addresses were similar but they are confused as it seems like they maybe from the same router though we are not sure and not very savvy with ip addresses.
Are these linked to the same router on the same day and at the same time. We are wondering if there is an issue as the first part of the address looks the same.
you appear to be and EE customer not BT retail - have you asked your question on your own EE forum
Sorry you misunderstood my post. From your other post you are an EE customer and I am saying this is a forum for BT RETAIL customers and asking if you have raised your question on your own EE forum
Hi does anyone know what it means if the first 16 digits in a public/external i pv6 address are the same but the last 16 are d ifferent. Are they going to different routers?
Hi again jhornby.
All the digits together make an ipv6 address, which is unique for each endpoint. Your network card generates the right hand 16 digits (64bits) itself, which is almost bound to be unique.
The first bit belongs to the network you are attached to. I have a BT network, and the first bit is:
2a00:23c6:f081:3d01 . Technically, I also have the last two digits, only '01' is used. This is called a 56bit prefix. That's nice of BT, and allows me to grow my private empire, so we can all have internet-enabled cigarette lighters.
Assuming you are at home. All your devices would have a similar prefix to mine. The structure is designed to facilitate routing of the packets.
Eventually, we will all get used to this, and realise it is a bit simpler. Especially as it almost self-configures.
