1364142	2014-01-01 23:55:00	My friends and acquaintances have been looking at my blog from time to time. I can see their IP addresses from visitor log. I know that this IP address must be either Mary, Joseph, or George, but I can't tell who it is exactly. Is there any way to tell? For example: I see this visit on my log: 71.130.215.24: adsl-71-138-215-24.dsl.irvnca.pacbell.net, Mozilla 5, MAC OS. I know it must be someone I know. But I can't tell who it is, and I can't ask all my friends. And I can't go look at their computers. Does anyone know if there is a way to tell? Gmail used to give the sender's IP address in email header. But I noticed that it has stopped doing this 2 years ago. Before, I can look at my friend's emails to me and find out their IP addresses, and then match them with the IP addresses on my visitor log. But I can't do that anymore. Is there another way? Another question: in 2010 my cousin sent me this email in which I can identify her IP: adsl-99-91-188-14.dsl.scrm01.sbcglobal.net. Then 3 months ago I noticed this person keeps visiting my blog: : adsl-75-26-172-57.dsl.scrm01.sbcglobal.net. It looks like my cousin: same service, same city. But the IP is different. I wonder if my cousin's ISP, SBC Global, has changed her IP in the 3 intervening years. How do I find this out without asking my cousin?	toothache (17218)

Or send an email with a unique link to click and see which ip hits it. And, yes, most 'consumers' are in dynamic ip pools, so their address will change from time to time.	fred_fish (15241)

For example, when SBC Global's server assigned my cousin the ip adsl-99-91-188-14.dsl.scrm01.sbcglobal.net in 2010, it remained stable for several months. I looked at her emails to me between April and August 2010, the ip address is the same. Could it have changed completely 3 years later? The thing about "dynamic pool" is that, when your ISP assigns you a new IP, only the last two digits will be different, not the first two. For example, today you have 99.91.188.14, 3 days later you have 99.91.33.56. How do you accuse people of copyright infringement out of the blue? I'm in United States.	toothache (17218)
