Curious, have you ever built your own DNS platform?

We (well, the working part - @Admin) are currently looking at building our own DNS setup for HostMaria, mainly so we are less dependent on Cloudflare/third-party DNS providers and can better support our own technical and registrar-side requirements.

One of the main goals is to have DNSSEC enabled by default, or at least made very simple, for domain registrations that we handle directly as an accredited registrar. In our case this includes registrar integrations through WHMCS, so the full workflow matters: domain registration, nameserver management, DNS zone creation, DNSSEC signing, DS record submission, renewals, transfers, and customer self-service.

At the moment, the main challenge is not simply running nameservers. That part is manageable. The harder part is finding the right infrastructure approach, especially reliable providers with proper network support for multi-region DNS and anycast. Most VPS providers are fine for normal DNS nodes, but do not support anycast/BGP, so they are not suitable for a true anycast DNS setup.

I would love to hear from anyone who has been through this already.

A few questions:

1. Have you built and operated your own DNS platform for a registrar, reseller, or hosting company?

2. If you run domain registrations through WHMCS, how do you handle DNS zone creation, nameserver changes, and DNSSEC/DS record management?

3. Did you build your own DNS stack, use a managed DNS provider, or use something like PowerDNS, BIND, Knot, NSD, etc.? .. Our choice - PowerDNS

4. For anycast DNS, did you use your own ASN/IP space and BGP, or did you rely on a provider that already offers anycast?

5. Looking back, would you build it again, or would you rather use an existing DNS provider with a good API?

We are still in the planning/testing stage, so real-world experience would be very useful, especially from anyone operating registrar services, hosting services, or WHMCS-based domain registrations.

@freddy, I would also be very interested to hear how hosting.de approached this, if you are able to share anything publicly. And, do you provide VPSs that support anycast?

@Whois-Search what about you guys? Do you have your own DNS?
