Setting up dynamic DNS

During corona lock down understanding that your broadband healthy is becoming part of your every day hygiene. In the UK you can setup remote monitoring of your home broadband quite easily:

In order to make this work however you need to have dynamic DNS configured on your home network. I have used my good old Synology for this as it has come with this dynamic DNS support on its base software package. But my good old DS213 has passed away a few days ago after 8 long years serving me and the family so superbly so I had to look for an alternative.

After a quick try of noip.com and understanding it requires regular maintenance I settled on freedns.afraid.org and registered a public subdomain against my actual dynamic IP address. Later checked changeip.com also on my Vodafone router but it has given me an error.

So this has given me the second practical use for my good old Raspberry Pi! I gained a token from www.duckdns.org and registered my subdomain. Created a crontab on my good old Raspberry Pi to keep my subdomain regularly updated based on:
