    i'm trying to figure out the originating IP of an email sender by looking at some headers.

    this email is from a gmail account --> a .edu email address
    (1) 10.100.7.xxx (private network)
    (2) 10.100.140.xxx (the same private network)
    (3) ag-out-0708.google.com (a google outgoing mail server)
    (4) recipient's IP

    I don't see the IP of the computer that the user sent the email from (the computer used to get to gmail.com) anywhere in here.

    this is a different email, this time from one gmail account --> another gmail account, both using gmail.com
    (1) 10.150.52.10
    (2) 10.151.135.10
    so this is one address on a private network to another. i'm assuming these are just two servers within gmail's system.


    Is it correct that if gmail is sent from the website (as opposed via POP or IMAP), that the sender's IP won't show up in the headers? so, instead the first originating IP will be a google server?

    Seems logical to me. Why would my IP appear in an email I sent that originates on a Google webapp server?

    well, obviously gmail logs the IPs of all accesses to the account via the web site, so i thought they might tack it on as the originating IP. possible, but i guess they don't do it.

    investigation at work that involves emails. i'm a prosecutor and i'm doing doing computer-related investigations. web-based email headers are something i haven't had to deal with yet.
