Public IP Address (Sky Max Router)

[Moon22]

When I browse to ipchicken.com on my iPad it returns, what I believe, my public ip address. When I do the same on my iPhone, connected to the same router, I get a different ip address.

Is this normal behaviour ?

Does the iPhone have its cellular data connection disabled?

It's not disabled but the wi-fi symbol is showing therefore I assume I am using wi-if. Anyway, all other devices are showing the same IP Address as my phone, it's my iPad that is showing a different IP (104.28.30.90).  I was wondering if it had anything to do with IPv4 / IPv6 !

I expect this is the result of MAP-T being used, which has been incorporated into the hub 6. This is technology similar to CGNAT where public ipV4 addresses are shared, but more efficient.
