How to SSH into a Raspberry Pi running at home from anywhere in the world without a dedicated public IP

How to SSH into a Raspberry Pi running at home from anywhere in the world without a dedicated public IP

The requirement

I have a raspberry pi running at home taking care of some home networking/automation stuff. I may at times find myself in a need to log into the Pi while not at home to check up on things. Without a dedicated public IP address this often proved a difficult task. Earlier I was using an ngrok tunnel for this. Read more about ngrok here. The problem with this was that ngrok would give me a different URL every time the Pi reboots. To get around this, I was using a system where I would send an email to a gmail account set up specifically for the Pi and the Pi would respond back with the ngrok URL. I will write a post about this later and link it here. Since I ran into some issues with this, I decided to go a different route which this article is about.
