Hello forum people and helpers!

I'm struggling quite a bit here on how to setup DDNS on a sub domain only. I work as IT Engineer but Networking has never been my strong suite and I'm currently transitioning into a Project Management role away from IT Systems Support, so please bear with me.

Type: SRV

Target: email.google.com
