    lets say I bought a domain on godaddy and I changed the dns to bluehost's servers. so domain was bought on godaddy, hosted on bluehost.

    Now I connect to the website and upload the files, using FTP (filezilla)

    Can godaddy see my ip address? what about bluehost?

    Yes to both.

    Basically in the process of performing a DNS lookup you tell godaddy your IP address so it knows where to send the response. Although when it comes to DNS sometimes there are other things at play and it might not happen every time (like DNS caching by you or your ISP).

    Same thing when you need to communicate with blue host servers via FTP. If they didn't have your address they wouldn't be able to respond to your requests.
