Need help on IP address lookup?

My 3rd-4th time receiving an email saying i signed up for some web cams which I know i didn't. I need more of an understanding what an IP address and how can you tell whether they're from the same person.


This is the email header I received

From that, I'm somewhat suspecting someone who manual signs me up for crap like web cams and some of her IP address came from the same place which in example.....

If anyone can help me, PLEASE, do. Thanks so much guys! I'm just really getting tired one after another blocking the emails and still receiving them.|||You already found out all the information you can really find out from someones IP address. If they are not using a STATIC IP provided to them by their internet service provider, then the perp is able to change his/her IP address whenever. You can, however, report the IP to their internet service provider and have them block all interactions with your IP.|||Unfortunately, the email headers that you sent do not have the information about who initiated the account on the service.





The only way that you would be able to do that is to contact the web site owners and complain to them. They probably will not tell you the IP address of the person that did it, but they will remove the account creation attempt and may work to block the person from doing it again in the future.|||IP Address can easily be changed in few minutes (using proxy to hide real IP address). What I would recommend is clicking on Report Spam button on your yahoo mail page. This would make yahoo add the sender to block list and all messages would go to spam folder.





Tip: Even if you find there real IP, you may not know who it is exactly. So no point in trying to match IP Address.|||I tried with

Below is what both free email tracking tools show:

It looks as Yahoo by default hide IP address from email sender. There is nothing that you can do about it.
