Netnod Primary DNS Azure DNS

Migrate DNS from Netnod to Azure DNS.

9 record types move as they are. 2 things work differently at Azure DNS, 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

Alias records are converted

Netnod alias records become CNAMEs below the apex. At the apex they need static addresses, and the preview shows which ones.

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

Netnod Azure DNS

  • ExactA@

    192.0.2.70

  • ExactAAAA@

    2001:db8::70

  • ExactMX@

    10 mx1.mail.example.net. +1

  • ExactTXT@

    "v=spf1 include:_spf.example.net -all"

  • ExactCAA@

    0 issue "letsencrypt.org"

  • ExactTXT_dmarc

    "v=DMARC1; p=reject; rua=mailto:dmarc@example.com"

  • ExactSRV_sip._tls

    100 1 443 sip.example.net.

  • ExactCNAMEwww

    example.com.

How the move works

  1. 1

    Connect Netnod

    Connect Netnod with read-only access (API token (Authorization: Token)).

  2. 2

    Connect Azure DNS

    Connect Azure DNS (Service principal (client ID + secret)). 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 Azure DNS

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

  5. 5

    Verify

    We query Azure DNS'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 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.

Good to know about Azure DNS

  • Azure alias records point at Azure resource IDs, which don't exist outside Azure.
  • Apex CNAMEs are not allowed. Use an alias record to an Azure resource or A/AAAA records.

Access we need: Reader on the DNS zone for the preview, DNS Zone Contributor to apply.

Questions

Will there be downtime moving from Netnod to Azure DNS?

Not if both providers serve the same answers during the switch. The records are copied to Azure DNS 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 Netnod?

No. We never write to Netnod. 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 Azure DNS and publish its new DS record. The cutover plan walks you through each step.
