Akamai Edge DNS RFC 2136 dynamic DNS (AXFR + DDNS)

Migrate DNS from Akamai to AXFR/DDNS.

17 record types move as they are. 2 things work differently at AXFR/DDNS, 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
  • SPF
  • RP

Alias records are converted

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

Akamai AXFR/DDNS

  • ExactA@

  • ExactAAAA@

  • ExactMX@

  • ExactTXT@

  • ExactCAA@

    0 issue "letsencrypt.org"

  • ExactTXT_dmarc

How the move works

  1. 1

    Connect Akamai

    Connect Akamai with read-only access (EdgeGrid API client (host, client token, client secret, access token)).

  2. 2

    Connect AXFR/DDNS

    Connect AXFR/DDNS (Primary server + TSIG key (HMAC-SHA256/512; SHA1/MD5 for legacy servers)). 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 AXFR/DDNS

    We snapshot the AXFR/DDNS zone, write in batches, and leave Akamai untouched.

  5. 5

    Verify

    We query AXFR/DDNS'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 Akamai

  • AKAMAICDN and non-DUAL AKAMAITLC records point at Akamai edge hostnames. Other providers have no equivalent, so recreate them as CNAME or ALIAS records by hand.
  • Apex ALIAS records are stored as AKAMAITLC records with the DUAL answer type. ALIAS records below the apex become CNAMEs.
  • TXT values can't contain double quotes or backslashes.

Access we need: DNS—Zone Record Management API: READ-ONLY for the preview, READ-WRITE to apply.

Good to know about AXFR/DDNS

  • We reach the primary only over TCP port 53 at a public address; servers on private networks must expose port 53 publicly and allow our egress IPs.
  • Zones can't be listed or created over DNS: list them in the connection and create them on the server first.
  • Records of types we can't encode (e.g. LOC, CERT) and DNSSEC records are skipped when reading; signing stays with the server.

Access we need: The TSIG key needs zone-transfer (AXFR) rights for the preview and an update-policy grant for the managed zones to apply.

Questions

Will there be downtime moving from Akamai to AXFR/DDNS?

Not if both providers serve the same answers during the switch. The records are copied to AXFR/DDNS 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 Akamai?

No. We never write to Akamai. 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 AXFR/DDNS and publish its new DS record. The cutover plan walks you through each step.
