This is not strictly OpenBSD based question but I highly value advises from this list.
I just logged into our ZoneEdit account which is recently acquired by EasyDNS of Toronto. To my horror I found out that our renewal date has conveniently changed from August of 2018 to two weeks from now. I called EasyDNS customer service who conceded that transition is very tricky and they can't help me with my ZoneEdit account but would be happy to open their own account. ZoneEdit can be reached only via e-mail. Long story short I am going to pull the trigger and changed our managed DNS provider. I just learnt that EasyDNS is BIND based. Any recommendation in particular for NSD based providers. Cheers, Predrag
