Dear lazyweb, does anyone have experience with the Dynamic DNS system on Unifi? I have domains at Gandi and Porkbun, and I cannot figure out how to delegate a dynamic subdomain to one of them. I am contemplating transferring to another registrar (Namecheap, maybe?) but it is not clear if "custom" might support my existing registrars or not, or whether the simple appearance in the drop-down list means they actually work, and I don't want to pay for multiple transfers to experiment
