Just a few days ago, the 24th i checked my public and it showed as 200 and something while the broadband network IP address was still in the 86 range?
Perhaps you are confusing your public IP address with your LAN address, which is allocated by the home hub DHCP server, and is within a private address range and not Internet routable.
As you mentioned earlier about the option "always use this IP address". That refers to your IP address on your private LAN, and has nothing to do with your public IP address.
There are no public IP ranges beginning with 200, used by BT Broadband. My webserver keeps a log of all BT IP connections originating from the main BT broadband domains.
I could provide you with a list, if you are interested?
I think you would only have to bother about the Android device if it was permanently connected and running some form of remote access application that opened ports via UPnP. Otherwise not an issue far as I can see. Some third party routers had/have some vulnerabilities. The Hubs on the other hand, despite their other issues, appear to be fairly secure routers.
Remote scanning of IPv4 is a relatively simple task. The FTP server running here when using IPv4 had access attempts often in the hundreds daily, some days much worse than others. On IPv6 nothing in the logs other than legit account access attempts.
Having a 'sticky' IP address is not a bad thing. Your systems (PC etc) AV and Firewall should provide any extra protection required.
That list of all BT's IP connections would be much appreciated as well, for checking logs especially. My email is *****@gmail.com
I did have several BT emails but hadn't logged for a few months and upon getting back in yesterday found them gone?
It just keeps saying there are no yahoo emails associated with that ID, then i got to another page which said they'd been deleted, i could understand if I'd been gone over 6 months but was more like four.
The Hub LAN IP address for devices will always be 192.168.1.* etc. Only if you change the default IP range in the router for example to 10.10.0.* or 192.168.0.*
Here is a snapshot which I have just taken, it lists the BT IP ranges logged recently. There are none beginning with 88.
There is nothing secret about these ranges, and they can be found by using tools on the Internet. This list also showns the most used ones.
This list can only be viewed from your BT Broadband connection and is not visible to anyone else, so don`t waste you time trying
18.104.22.168 is an Orange/EE GPRS service. You were using your mobile on the EE mobile network at the time & that was the public IP it assigned to it.
Oh, I forgot, BT mobile is a MVNO on EE's mobile network, so it could just as well have been a BT mobile.
