Re: Private IP address with yahoo messenger

Hi
Here are some of the possibilities:
1)Your machine might be compromised .
2)It may be not from your YM but from your browser the subject is
getting the IP.Ensure that no  JavaScript,Applet(JAVA),Cookies,ActiveX
pulgins running on your YM cleint or in the browser.Use socksification
in your browser, This will enable relaying all the information your
browser or any other software sends and transfers to the proxy server.

Try Logging into the webbased YM like Meebo.com  check the subject can
still tell your IP .then we can conclude that your machine or channel
is comprimised not YM .
which version YM  are you using ?or are you using the GIAM like client.

Hope to hear from you.
Regards
Aditya K
