When I try to trace Ethereal tcp packets containing HTTP protocol, I see that the addressing (in the first column), do not follow the addressing of the whole packet but its specific to the HTTP data.

This is a Wireshark (the new name for Ethereal, as of a little over a year ago) issue, not a WinPcap issue; I'm redirecting it to the wireshark-users mailing list, which is the list where questions about Wireshark should be asked. Further discussion should take place on that list. See

What do you mean by "follow the addressing of the whole packet" and "specific to the HTTP data"?

The first column is probably the frame number, and the second column is usually the packet time stamp. Do you mean the third column? If so, that's usually the source IP address, which would be the IP address that sent the packet; IP has no idea whether it's sending HTTP or not. An IP datagram has an IP address; there is no notion that part of one IP datagram has one IP address and another part has another address, so the only addressing is "the addressing of the whole packet" - there's no addressing specific to the HTTP data.
