How do I find out my real ip?

[J1234]

I'm trying to set up a dynamic dns address on dyndns.com, and I can't find my real ip address. The one it automatically fill in is the one used to connect to my router, 192.168.0.1, like most others, and if I look on whatsmyip.com it shows me a different one, but it also connects to my router?

Also it displays the 192.168... one through run, cmd, ipconfig. Am I doing something wrong?

I'm trying to set up a ftp with a dynamic ip by the way.

Also if I type whats my ip into google the search results show some starting with 66, but each one is different.

Hmm I must be doing something else wrong, it wont connect at all.
