SA, You’re one of the brightest Freepers in tech so here’s a question...

I bring my laptop to work (Dell 2009 XP SP 3 iNSPIRON) and I point the mouse to the bars of the wifi and gives me the ‘address’ as 192.168.1.74.

Obviously under whatismyipaddress.com, it;s a different #...

Now I bring it home, point the mouse at the bars and it gives me the same “address’ 192.168.1.74,but my ip address is obviously different from the office..

Is this normal?

Yes, it is normal. The 192.168.1.74 address is strictly an internal IP--that is, it is used only on your work network and your home network.

192.168.x.y are considered reserved for private networks and not for the internet at large. So your work (and home) routers are assigning that address to your computer for those networks. The external-facing connection, though, has two addresses--one for the outside, and one for the inside (192.168.x.y). The outside-facing connection is the one being reported by whatismyipaddress.com.
