Namecheap BasicDNS NexDNS

Migrate DNS from Namecheap to NexDNS.

8 record types move as they are. 1 things work differently at NexDNS, 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.

A typical Namecheap zone at NexDNS

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

Namecheap NexDNS

  • TranslatedALIAS@

    app.example-host.net.

    Stored as a NexDNS ALIAS record to app.example-host.net.

  • 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"

  • ExactCNAMEblog

    example.github.io.

  • UnsupportedURL301go

    Not migrated

    URL301 is a Namecheap redirect feature, not a DNS record. Recreate it as a redirect rule at NexDNS.

  • ExactCNAMEwww

    example.com.

How the move works

  1. 1

    Connect Namecheap

    Connect Namecheap with read-only access (API user + API key, with our egress IP allow-listed).

  2. 2

    Connect NexDNS

    Connect NexDNS (API key (Bearer, nxd_ prefix)). 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 NexDNS

    We snapshot the NexDNS zone, write in batches, and leave Namecheap untouched.

  5. 5

    Verify

    We query NexDNS'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 Namecheap

  • Namecheap's API replaces the whole host list on every write, so we always read, merge and then write.
  • SRV records can't be managed through the API.
  • URL redirect records are Namecheap-specific and aren't real DNS records.

Access we need: API access enabled under Profile → Tools, with our static IP added to the allow-list.

Good to know about NexDNS

  • The SOA record and the apex NS records are managed by NexDNS and can't be changed, so dual-hosting a zone with a second provider isn't possible.
  • Records are written one value per request against a per-account rate limit, so large zones take a while to apply.
  • Only A, AAAA, CNAME, MX, TXT, NS, SRV, CAA, PTR, ALIAS, DNAME, DS and TLSA are supported; ALIAS is the way to point the apex at a hostname.

Access we need: zones.read and records.read for the preview; add records.write to apply and zones.write to create zones or switch DNSSEC. API access needs a Pro plan or higher.

Questions

Will there be downtime moving from Namecheap to NexDNS?

Not if both providers serve the same answers during the switch. The records are copied to NexDNS 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 Namecheap?

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