    I have a broadband cable connection, but I use another ISP to connect to some websites using my cable connection.

    I was wondering if my ISP passes their IP along in the header or can they also pass mine along to them also?

    Example:
    broadband isp ---> xxx.isp ----> blackhatworld

    Which IP will blackhat world see? More importantly, can the second isp (xxx.isp) pass along the original IP address?

    referer != IP

    just load one of those "whats my ip" sites to see which IP is seen.

    Do you use xxx.isp selectively?

    Thanks bruce for the quick reply.

    I thought referrer == IP address for some reason. It just means what page you came from before visiting their site, right?:)

    I do use whatsmy*ip. It is different from my ip. I was just wondering if a different ISP has the ability to pass along my original IP address?

    I generally thought it would depend on the service that your ISP provides. Like in my country, Singapore, my ISP is abit funny. It is neither a static or dynamic IP addy. Because each cluster of account are "given" a bunch of IPs which their connection will be shared thru. However, if you do not refresh your modem, your connection is stuck with the same IP that it was assigned the moment it connected to the internet.
