IP address looks like Dword. maybe.. idk

This morning I noticed that my IP addresses are showing up different.
instead of the normal 192.168.1.0
it looks like 2001:0:4136:9e73:1897:2b06:b39e:c1bc

This is a system wide problem.
it looks the same in DOS with ipconfig, it looks the same in my firewall and in network adapter propertys, and on my cisco router. all the ipaddresses look like this so I can't tell what they are and Now I'm having trouble setting up the xbox and wii.

I just want to know how to have my system show the regular IP addresses. (example: 192.168.1.0)

Windows 7 64bit
realtek NIC
Cisco WRT400N

Okay, both IPv4 and IPv6 are enabled on the internet property - network tab.
How exactly do I have it switch to use one over the other without disabling IPv6 all together?

Go into your network adaptor's settings, on each machine... in the protocals list simply uncheck the ipv6 entry. (Don't uninstall it).

The only real difference between ip6 and ip4 is that you have 6 dwords instead of 4 bytes of addressing. The internet is still on ipv4 and likely will be for quite some time to come...

Okay great, I did that after reading up on IPv6. What you said confirms what I read about it not really being used as much at the moment.

This solved everything. All my IP addresses system wide are looking familiar now.

Thanks to everyone for your responses and help.
