Scary IP address

[JohnGJ]

I am attempting to install Plex media server app. Having downloaded it the installation dialogue box contains the following message.

‘SECURITY ALERT’

‘Another device is attempting to sign in to your Plex account. You should only continue if you know this device and intend to grant it access

31.49.56.217 ( Braintree, England, Essex, United Kingdom)’

Having looked up the IP address it would seem to be a BT address. But is it?? The physical address seems to make no sense and makes me suspicious. If it is legitimate why would BT wish to have access to my Media Server?

Any observations or answere would be appreciated. Thanks John

What's the public IP on your router presently?  (The address often changes when the hub does a 14 day reboot and 31 is not unheard of.  I get a 31 myself at times.  The location also takes time to update).

Indeed, I suspect it is your IP address.

Thank you for the response. My router and al the items on the network begin with numbers starting 192.168. ….

@JohnGJ they are your private addresses on your LAN, not your public IP address.

[JohnGJ]

Thank you. The responses demonstrate my naivety in this area!! I will go and look. John

There are two types of address.

The 192.168.X.X are internal to your network and known as private address.  (Private not so much in the sense of security but because they are internal to you network).

There is also your connection to the outside world.  This is your public address.  In my experience BT’s can start with any of 31, 81, 86 or 109.

Assuming you have a Smart Hub 2, if you go into Advanced settings > Broadband, it is one of the addresses near the bottom, listed as “Broadband IP Address”.

[JohnGJ]

Thank you. It seems I have a list of 4.  

Broadband IP address begins with 109.247. ……..

Default gateway begins 172.16. ….

Broadband primary DNS and the secondary DNS both begin with 81.139. ….

None look like the address I am concerned about.

The Dynamic DNS is marked as ‘OFF’

A few things, your public IP address is the 109 address which would gave been revealed by the link @rbz5416 posted.

It won't be BT attempting to connect, it will be a BT customer having that address as their public IP address.

Do you have a BT mobile connected to 4/5G rather than WiFi that might have that address?
