Does google track the IP address of the website from where the backlink has been created

I believe that guest post is more successful nowadays as the backlink is generated from the guest post is from the different IP address as you get the link in guest post site owner or editor.

In article and web 2.0 we just submit the post and created the link from the same IP address through which we have created entire backlinks.

By tracking the IP address, Google may know whether the link is real or created by the company itself.
