Ip address please help

[Keithlan1978]

I've got an O2 dongle to use as my ip is static through my Internet provider and I've tried using the dongle which is surprisingly fast by the way but something seems a bit weird although it might be totally normal

Whenever I use the dongle I disable the wireless on my laptop and connect to the Internet through the dongle then I go to IPBurger and check the ip address which has obviously changed from my wireless Static IP address

I then go to google and type in what's my ip address and at the top it says your public ip address is but this ip address is different to the one showing on ip burger

Then if I click on one of the google links my ip address is different on them to the one on IPBurger and also the one on google that says your public ip address is etc etc

Is this normal as I thought it would of been the same on all sites?

When I connect through my wireless Internet and do the same thing my ip address is the same on IPBurger and my public one on google

Thanks
