BT Infinity static IP addresses with a Home Hub - not showing correct IP

Recently, I was involved in the setup of a new Infinity line for a business. They ordered the line and then requested 5 IP addresses but weren't sure how to get them working.

Once again, BT were not overly helpful with how to use the static IP addresses.

The client was told that the should use 56.23.45.62 (not their actual IP address, but works for this example) and that was it.

If you log into the homehub and go to the "advanced" settings page you can then select "Static IP".

In here, you need to enable it and put in your routers address as they call it. To get this working correctly, we had to enter "56.23.45.61" as using the last available IP (56.23.45.62) would not let the device connect.

However, the really odd thing is that when you reboot, the router will still get a seemingly random IP address not related to the static IP at all.

If you've set it up right, the statics will still work - they just wont appear on the router!
