Namecheap BasicDNS deSEC
Migrate DNS from Namecheap to deSEC.
7 record types move as they are. 3 things work differently at deSEC, 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

Alias records are converted
URL, URL301, FRAME, MXE aren't available
TTLs below 3600s are raised
A typical Namecheap zone at deSEC
Example records for example.com. Open any flagged row to read why it changed.
Namecheap deSEC
- UnsupportedALIAS@
Not migrated
@ is an alias to app.example-host.net at the zone apex. deSEC doesn't support apex aliases or CNAMEs.
- 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"
- TranslatedCNAMEblog
example.github.io.
TTL 1800s is outside the allowed range. Set to 3600s.
- UnsupportedURL301go
Not migrated
URL301 is a Namecheap redirect feature, not a DNS record. Recreate it as a redirect rule at deSEC.

How the move works
- 1
Connect Namecheap
Connect Namecheap with read-only access (API user + API key, with our egress IP allow-listed).
- 2
Connect deSEC
Connect deSEC (API token). Write access is only used when you apply.
- 3
Review the preview
Check every record marked Review or Unsupported. Each one explains what changes and why.
- 4
Apply to deSEC
We snapshot the deSEC zone, write in batches, and leave Namecheap untouched.
- 5
Verify
We query deSEC's own nameservers for every record and compare the answers before you switch.
- 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 deSEC
- The minimum TTL is 3600 seconds for most domains (deSEC sets it per domain) and the maximum is 86400.
- ALIAS/ANAME records and apex CNAMEs aren't supported; use A/AAAA or HTTPS records at the apex.
- Every zone is DNSSEC-signed automatically. Give the DS records to your registrar to complete the chain.
Access we need: Any token can read all RRsets. Applying needs write permission on the RRsets (token policies can restrict it); creating zones needs perm_create_domain.
Questions
Will there be downtime moving from Namecheap to deSEC?
Not if both providers serve the same answers during the switch. The records are copied to deSEC 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 deSEC and publish its new DS record. The cutover plan walks you through each step.
