Google Cloud DNS NetBird

Migrate DNS from Cloud DNS to NetBird.

3 record types move as they are. 2 things work differently at NetBird, and the preview shows exactly which of your records they affect.

Free preview. Read-only. Nothing changes until you apply.

What works differently

Generated from the same provider capability data the migration engine uses.

Moves as-is

  • A
  • AAAA
  • CNAME

Routing policies are flattened

NetBird has no routing policies. Weighted, geo and latency sets collapse into one set of answers, and failover keeps only the primary. Each one is flagged for review.

A typical Cloud DNS zone at NetBird

Example records for example.com. Open any flagged row to read why it changed.

How the move works

  1. 1

    Connect Cloud DNS

    Connect Cloud DNS with read-only access (Service account key (JSON)).

  2. 2

    Connect NetBird

    Connect NetBird (Personal access token (Authorization: Token) + optional self-hosted management URL). Write access is only used when you apply.

  3. 3

    Review the preview

    Check every record marked Review or Unsupported. Each one explains what changes and why.

  4. 4

    Apply to NetBird

    We snapshot the NetBird zone, write in batches, and leave Cloud DNS untouched.

  5. 5

    Verify

    We query NetBird's own nameservers for every record and compare the answers before you switch.

  6. 6

    Switch nameservers

    Lower TTLs a day or two ahead, remove any DS record if DNSSEC is on, then point the domain at the new nameservers at your registrar.

Good to know about Cloud DNS

  • Routing policies (weighted round robin, geolocation, failover) don't carry over to most providers.
  • Apex CNAMEs are not allowed.

Access we need: roles/dns.reader for the preview, roles/dns.admin to apply.

Good to know about NetBird

  • NetBird custom zones are private DNS served only to peers in the zone's distribution groups; creating a zone needs at least one distribution group ID.
  • Only A, AAAA and CNAME records are supported.
  • Self-hosted management servers are often on private networks: we only connect if the API is exposed publicly over HTTPS, because private and internal addresses are refused by design.

Access we need: A service user whose role has DNS read permission for the preview and DNS create/update/delete to apply (Admin or Owner).

Questions

Will there be downtime moving from Cloud DNS to NetBird?

Not if both providers serve the same answers during the switch. The records are copied to NetBird and verified before you change nameservers, so resolvers get the same answer from either side while caches expire.

Do I have to delete anything at Cloud DNS?

No. We never write to Cloud DNS. Keep the old zone for a week after cutover so you can switch back instantly if anything looks wrong.

What about DNSSEC?

If DNSSEC is on, remove the DS record at your registrar and wait for it to expire before switching nameservers. Then enable DNSSEC at NetBird and publish its new DS record. The cutover plan walks you through each step.
