Hi, I’m curious as to why my external IP address seems to be changing almost on a daily basis? What is it that BT does most days (usually late at night/early hours) that causes this? Some kind of daily line test? To be honest in the several years I’ve had Infinity it’s always been an issue. Sometimes it’ll go weeks without changing or I’ll get a run where it happens every few days. There have been times when it’s changed daily and seemed to stop doing it after a while. But lately it’s been a daily occurrence and i would be keen to know why BT keeps changing it. I have a NAS drive and a webcam that I often access externally via my phone. The apps I use necessitate that I know the external IP so by it keep changing it gets a little annoying. I know I can get something kind of DNS tracker but I’m more interested in why the IP is not staying the same for longer periods of time. Checking my netgear router logs I see one very brief internet disconnect and reconnect of a few seconds where the IP changes. You wouldn’t even notice if you were using the internet it’s so brief. My IP profile remains consistent in the mid to late 50s for download speed and my upload is always around 11/12. I’m sure if there was a line problem that would plummet. So why is BT doing something externally to cause this IP change to happen so often?
The IP address change is due to the disconnects. Line noise is the biggest cause of disconnects. Do a quiet line test, best with corded phone. 17070 option 2.
BT do not issue static IP addresses to residential customers so your IP address will change whenever there is a disconnect or when BT decide to change it which can be frequently.
This will as you know cause problems if you need to access a camera or NAS externally.
I appreciated that you want to know why the IP address is changing more frequently but even if you find out why you would be best to sign up to an IP service such as No-IP which will allow to to access those devices even when your IP address changes.
If you go onto the web sites of the companies such as No-IP and look through their support pages you will see what is involved in using the service and how to set it up.
