Oh, the good-old-days, when DYNDNS was free – and so was zoneedit. Move forward to today, where everything costs (and it should!).
Since I’m so heavily invested in Google from a tech perspective, I opted in to try their registrar service: Google Domains.
Transferring in was easy (see ya 1and1!) and setting up custom resource records (DNS entries) was simple.
Then, I read about Dynamic DNS being included with the service (along with free domain privacy) and I was intrigued.
Google offers their ‘help’ page here – but it left me questioning something.
I’m not going to re-write their doc, however, if you have any subdomains (www, blog, etc), THOSE are your synthetic Dynamic DNS records.
