How to Know the IP Address of a Person by Sending an E-mail?

IP Address holds a lot of importance in the hacking world!!! once an attacker grab hold of an IP Address of a person he/she can initiate different types of attack which is very unethical whereas tracking email and thereby get the IP Address of the user is even more unethical.So,i have come up with this post to let the innocent users know about this risk and how to detect it.

How this is carried out?

1. First signup in readnotify.com

2. Login to your email account which you have used to signup for readnotify.com

3. Compose an email and write the email of the person whose IP Address you want to grab and put a ".readnotify.com" extension at the end as shown in the image below but the best part is the recipient will not see it.

4.Write something in the message part and send it.

5.Whenever the recipient will open the mail you will be notified by an email and you can also signin to your readnotify.com account to see the information procured there you can find the IP Address of the PC where he/she has opened the email as shown in the image below.

What are the information shown by Readnotify.com?

Date and Time he/she has opened the mail.
Location of the recipient as per ISP.
Recipient IP Address along with portno.
For how long the email was read.
How many times the email was read.
To whom it was forwarded
If it was again opened in a different PC.
Url clicks if present in the message.

How Readnotify.com works?
Actually readnotify.com sends an automatic generated image with the email and this hidden image gives the recipient's IP Address.

Now as you all know how to do this ,now the comes how to detect this attack.

How to detect an email has ".readnotify.com" extension and is a tracking email?

1.For detecting this one has to open the mail once but before opening one has to use a proxy server so the mail cannot track the IP Address.

2.Open the header of the email and search for "Received:"there one can find .readnotify.com extension and an error message saying that the google could not find the actual email ID of the sender as shown in the image below.
