I had my Airport Extreme router running my wireless network and the IP address was
Then I reset everything and deleted the old network and created a new one with the same name.
It seems to be working fine but now the router IP address shows
Why did it change and should it be like before?
I have 3 Mac computers, an iPad and an Airport Express and they all now have IP addresses starting with 10.0.1.
Why is this happening?

Early 2009 iMac 24", Mac OS X (10.6.2), 4 gig ram

    The default IP address of all the Apple routers is, so if you reset the device or the settings back to defaults, this is the setting that you will see.

    The 10.0.1.x range works just fine. There's no particular reason for it to be unless you happen to like that number better. There's no performance advantage to either the 10.0.x.x or 192.168.x.x range.

    Your next question may be how to change back to

    Open Airport Utility - click Manual Setup
    Click the Internet icon
    Click the DHCP tab below the icons
    Locate the setting for DHCP Beginning Address and change this to 192.168
    Click Update at the lower right to save your settings

    You'll need to power cycle your entire network now.
