Finding my *real* IP Address?

[Tiyana]

Hi, I'm using a Cable modem that is split through a router to both my roommates computer and mine. When I type IPConfig in the command prompt it lists my IP as 192.168.X.X which is the IP that my computer recieved from the router. How do I determine the actual IP address that was sent by my ISP?

I typed IPConfig /all and got the following information (certain stuff edited out):

Dhcp Enabled. . . . . . . . . . . : Yes
Autoconfiguration Enabled . . . . : Yes
IP Address. . . . . . . . . . . . : 192.168.X.X
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.X.X
DHCP Server . . . . . . . . . . . : 192.168.X.X
DNS Servers . . . . . . . . . . . : 204.X.X.X
63.X.X.X

Are either of those last IP's my actual IP or are they simply the IP address of the DNS servers at my ISP? Thanks
