DNS migration checker

Find out what's involved in moving a domain before you touch anything: who hosts it, whether DNSSEC is on, and exactly how its records land at the provider you're considering.

Free. No account. Read-only.

DNS host and registrar
From the nameserver delegation and the registry's RDAP record.
DNSSEC state
Whether a DS record exists and matches the zone's keys, which decides the order of your cutover.
Public records
The apex plus about 80 common names, asked directly of the zone's own nameservers.
Compatibility with 66 providers
Every record run through the translation engine, with the reason behind each change.

What it flags

The problems that turn a DNS move into an outage.

  • Proxied Cloudflare records that would expose your origin
  • Apex CNAMEs and aliases the destination can't express
  • Weighted, geo and failover routing that won't carry over
  • DNSSEC that needs a DS removal before switching
  • TTLs below the destination's minimum
  • Provider-only records such as URL redirects

Questions

Does the checker change anything?

No. It only sends ordinary DNS and RDAP queries, the same ones any resolver makes. Nothing is written anywhere and no account is needed.

Why does it say the record list is partial?

DNS doesn't let anyone list a zone's records unless the nameserver allows a zone transfer, and almost none do. We check the apex and about 80 common names. For the complete zone, connect your provider with read-only access or paste a zone file export.

Is it really free?

Yes. The checker, the preview and all the tools are free. You only pay if you have us apply a migration.
