Auto Pingbacks after post edits?

Hi WP Crew,
A quick one but rather confusing.

After making some edits to a post, I was getting comments showing up on each of the posts I edited, all from the same I.P and then I got emails notifying that I have pingbacks waiting for my approval, the email goes like this:

A new pingback on the post “(Postname)” is waiting for your approval

Website : (example – changed for security) (IP: xxx.xxx.xxx.xxx , somewhereontheweb.com) < I.P is the same on every pingback I have and the website mentioned here is where my website is hosted!
URL : https://www.somewhereontheweb.com (example – changed for security)
Pingback excerpt:
[…] (postname) – (example – changed for security) […]

What is causing this? I’ve edited other posts that I created a few days back and they didnt create ping backs. And I’ve done previous edits to the same posts that I am originally referring to with no pingbacks created at all?!

Confused…
