BT WiFi and class A addressing
« on: July 01, 2023, 10:41:33 AM »

In February BT updated the software on my home hub, and the class A address I had entered in the hub disappeared. When I tried re-entering it I got a message saying I couldn't use that address because the whole of the 10.0.0.0 network was now reserved for BT WiFi.

After five months of being given the runaround by BT they still don't know how to disable the feature that prevents the use of the 10.0.0.0 address range.

Anyone else found a way around this, short of buying a 3rd party router?

Hi,

A few years ago, if you were opted out of BT WiFi, you could use 10. on the Hub. Last year I temporarily used the BT Smart Hub 2 where I also tried to use 10. (I'm opted out of BT WiFi), but the hub would not let me use it. I ended up using my own router - I don't like using ISP routers as you are typically limited in what you can configure, especially with the BT Hub. It is designed for plug and play to keep customers away from customer services.

To be fair I avoid the 10. range anyway as its also used extensively by VPNs.

At least they haven't done what AT&T did to my friend in the US, they completely changed his range from 192.168.0 to 192.168.1, breaking his ability to remote into my network.  I had to completely redo my own addressing to fix it - fortunately most of it was DHCP static leases.

I get that 10. is quicker to type, but its long been standard to use 192.168 for home use.

You can use 10.0.0.0/8, 172.16.0.0/12 or 192.168.0.0/16. Those are standard RFC1918 addresses for private use. Whilst true, using 10.x.x.x's can conflict with work networks, there's no reason you should not be able to use them.

To answer the OP's question, first thing I would be doing would be swapping out the router, but I appreciate this isn't for everyone. Or simply use any of the ranges outlined above instead.

I'm aware you can, doesn't mean you should for that very reason. ;)

Some ISPs even run CGNAT over a 10, presumably their implementation pre-dates the CGNAT specific reservation?
