Scary IP address

[WSH]

It could also be a left-over from the address you had before the last reboot of the router.

(By the way, default gateway is basically BT’s address at the other end of the connection and DNS is like the phone directory for looking up the IP addresses of the web sites you are trying to connect to).

@licquorice  Yes you are correct the link  @rbz5416  kindly provided was indeed my Broadband IP, thanks. I did not realise that they were the same. But as I mentioned they appear totally different from the one in the warning. I will look into the iPhone connection.

I wouldn’t worry about it.

31 doesn’t come up very often in my experience.  My own logs show I had a 31 address on the reboot on 17th Match 2024 and then not again until the reboot on the 28th Jan this year.

That IP address (31.49.56.217) is likely just a general BT-assigned IP. It could even be your own device if you're on BT Internet. Sometimes, Plex routes sign-ins through the cloud or another network layer, and it might look a bit strange. If you're setting up Plex and logging in from your own home Wi-Fi, it's probably fine.

But if you’re unsure, deny it for now, then go into your Plex account settings and check recent devices or enable 2FA for extra safety. Better to be cautious, but it doesn’t instantly scream “hacker.”

Many thanks to all for taking the trouble to reply. Oddly I have downloaded the app. again on another computer and this time the alert shows, what I now know to be my external IP address, and it shows my York location rather than Braintree! Going back to the original computer brings about the same result. i.e my own external IP and location. The way the physical address is structured still seems odd as does the Braintree address. 
I will only ever be logging in from my home computer so perhaps I am being a bit paranoid.

Thanks once again for all the comments. John

As I said, BT’s system takes a while to catch up with itself when the public IP changes & the location is approx. at best.  There are also differing formats for the address, depending on what it is being used for. 

When you say looks odd, is it something like: host109-154-xx-xx.range109-154.btcentralplus.com?

If it is being taken from DNS as a reverse lookup it may have a format something like: 0.154.109.in-addr.arpa

Both are normal and nothing to worry about.

What I ment by the address looking odd I was referring to the location address and how it was written. Braintree, England, Essex, United Kingdom 

I have searched for the IP address in my original post and it does indeed come up as owned by BT central plus.
