Google Cloud DNS Netnod Primary DNS

Migrate DNS from Cloud DNS to Netnod.

15 record types move as they are. 2 things work differently at Netnod, 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
  • MX
  • TXT
  • NS
  • SRV
  • CAA
  • PTR
  • DS
  • HTTPS
  • SVCB
  • TLSA
  • SSHFP
  • NAPTR

Routing policies are flattened

Netnod 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.

TTLs below 60s are raised

Netnod's minimum TTL is 60 seconds. Shorter TTLs are raised to 60s and shown as translated.

  • ExactA@

    192.0.2.40

  • ExactMX@

    10 mx1.mail.example.net. +1

  • ExactTXT@

    100 1 443 sip.example.net.

  • ReviewAeu

    Geo routing isn't available at the destination. All 2 answers are served together as simple round-robin.

How the move works

  1. 1

    Connect Cloud DNS

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

  2. 2

    Connect Netnod

    Connect Netnod (API token (Authorization: Token)). 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 Netnod

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

  5. 5

    Verify

    We query Netnod'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 Netnod

  • Netnod publishes no public API reference; the adapter follows Netnod's official Go client, and TTL limits are not documented.
  • Each change replaces a whole name+type set, so records disabled in the Netnod portal are dropped when that set is edited.
  • New zones get Netnod's default nameservers; zone transfer keys and NOTIFY targets must be set up with Netnod separately.

Access we need: A Primary DNS API token for the account. Netnod tokens are not split into read and write scopes, so the same token is used for preview and apply.

Questions

Will there be downtime moving from Cloud DNS to Netnod?

Not if both providers serve the same answers during the switch. The records are copied to Netnod 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 Netnod and publish its new DS record. The cutover plan walks you through each step.
