Much like every house in a neighborhood has a number, every computer connected to the Internet has an IP (Internet Protocol) address.
When a computer initiates a connection to another computer, that connection is known to “originate from this IP address,” and the system on the other end may choose to either allow or deny communications from the source of origination.
This is essentially like contacting your telephone company and requesting that they deny harassing calls from a particular phone number.
If the person that you were blocking decided to change his/her number, that number would still be blocked and if the new owner of the phone number tried to call you, he/she would not get through.
It’s not the “person” that you’re blocking, it’s the number. If this individual used a friend’s phone, a pay phone, or any other telephone to contact you, they’d be able to get through.
Your domain name has to be tied somewhere to an IP address.
It could be shared, it could be your own.
Ultimately when you’re dealing with email you’re going to want it to be your own. So, it is important to make sure that the IP address (or addresses) from which we choose to send our email does not have any restrictions (or problems) on it, either now or in the future. This is one of the main factors that will keep your email from getting through to your intended recipients.
