DNS Provider Sync · Vultr
Vultr's DNS is free, anycast, and refreshingly simple. DNS Spy adds what simple doesn't include: independent monitoring of every record, from outside Vultr's network.
No credit card required · 7-day trial · Read-only API access
Vultr's DNS is deliberately minimal: fast anycast serving, a clean control panel, a straightforward API. Minimal also means no built-in change alerting, no record history, and no external verification. DNS Spy imports your complete Vultr record list via the API and monitors it from resolvers around the world — every change is alerted, every value is versioned, and nameserver sync is verified continuously.
Vultr tokens are account-wide, but Vultr offers something most providers don't: access control by source subnet. If you want defense in depth, you can restrict your token so it only works from specific networks. Combined with DNS Spy's encrypted-at-rest token storage and read-only usage, that makes a Vultr connection one of the most lockdown-able integrations we support.
Vultr instances get rebuilt, resized, and redeployed — and every new IP needs its A record updated. The failure mode is always the same: someone updates the server, forgets the DNS, and traffic flows to an IP Vultr has since handed to a stranger. DNS Spy catches both directions — the record that changed when you didn't expect it, and the record that didn't change when it should have (still pointing at infrastructure that stopped answering).
In your Vultr account, go to Account → API and enable your Personal Access Token.
Optionally add DNS Spy-only access control: Vultr lets you restrict the token to specific source IP subnets.
Paste the token into DNS Spy under Team Settings → DNS Providers and click Test Connection.
Import your domains — every record arrives and resolver monitoring starts immediately.
Read more about how imports, recurring sync, and resolver-based monitoring work on the DNS Provider Sync feature page.
Enable your personal access token (Account → API), connect it to DNS Spy, and import your domains. DNS Spy monitors every record from multiple resolver locations with alerts via email, Slack, Discord, or PagerDuty.
Vultr tokens are account-wide, but you can restrict them by source IP subnet in your Vultr API settings for extra safety. DNS Spy stores the token encrypted and only performs read operations against the DNS endpoints.
No. Vultr doesn't offer AXFR, so the API is the only way to enumerate a complete zone — which is what DNS Spy's provider sync automates, with recurring re-checks that pick up new records automatically.
Yes. DNS Spy's Security Center audits DNSSEC configuration among 40+ automated checks, independent of provider sync. If you've enabled DNSSEC on a Vultr domain (it's off by default), DNS Spy validates the chain; if you haven't, the Security Center will suggest it.
Connect with a read-only token, import every record, and get alerted the moment anything changes. Free for 7 days.
