Ip adress

Thanks everyone for replying

It is how it is designed to work.

The main way the network knows it is you is not through the IP address. It uses other things.

But to make the internet work it has to give you an ip address. It just temporarily assigns you one from a list of numbers.

It shouldn't cause you problems, unless you lose connection to the network a lot.

We ran out of IPv4 addresses many years ago and don't have enough to go around.

You are probably on CGNAT (which means you are sharing your IP address with many other users), but even if you are not on CGNAT, you will still be assigned one dynamically, which means it will change from time to time (especially if the device reconnects or moves between cells).

If you want your own fixed IPv4 address on a cellular connection you will have to pay a lot of money for it.

my up address on my phone cellular without WiFi keeps changing. What causes that?

If you are on mobile data rather than connected to WiFi then it is your service provider (O2, Vodafone or whoever) who is doing this. It is done this way because they have more devices connecting than they have IP addresses to allocate to them, so they make them all time lmited so after a few hours if you are not on their network then your IP address can be used by someone else.

It isn't a trivial thing for them to just get more addresses which is why they do this.

I think it's not unusual. At one point the only way to get a stable IP address was to have a business account, otherwise they can shift. Can cause issues for remote work set ups.

Hi, did you take it from your phone settings, or from a website? And what approximate interval of time was it?
