I host my private servers at Hetzner, a really nice, reliable and cheap german webhoster.
Previously I managed my DNS zones with Route 53 from Amazon. There I paid 50 cents per zone per month. I have multiple zones so this adds up at the end of the year.
Then I learned from a fellow user of one of our Ansible collections that Hetzner provides this service for free! So now I’m moving all my DNS to Hetzner.
