How the move works
- 1
Connect OpenWrt
Connect OpenWrt with read-only access (LuCI URL + username + password (LuCI JSON-RPC, luci-mod-rpc)).
- 2
Connect Bunny
Connect Bunny (Account API key). 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 Bunny
We snapshot the Bunny zone, write in batches, and leave OpenWrt untouched.
- 5
Verify
We query Bunny'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 OpenWrt
- Routers usually sit on a private network; we refuse private and internal addresses by design, so LuCI must be exposed publicly over HTTPS with a trusted certificate (ideally allow-listed to our egress IPs).
- dnsmasq local records have no per-record TTL, so every record is reported and written with a fixed TTL of 300 seconds.
- Records live in one flat list on the router, so a zone is simply the set of names under that domain; wildcard CNAMEs, null MX and null-target SRV records are not supported.
Access we need: LuCI logins are not scoped: the account can read and change the whole router configuration. We only touch dnsmasq host, CNAME, MX and SRV entries in /etc/config/dhcp.
Good to know about Bunny
- Pull Zone, Script and Flatten records, and disabled records, aren't migrated. Redirect records are read as URL redirects to recreate by hand.
- Records that use smart routing (latency or geolocation) or CDN acceleration are flagged and never changed by us.
- An apex CNAME is flattened by Bunny, so it can point at any hostname.
Access we need: The account API key has full access. There is no read-only key, so rotate it after the migration.
Questions
Will there be downtime moving from OpenWrt to Bunny?
Not if both providers serve the same answers during the switch. The records are copied to Bunny 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 OpenWrt?
No. We never write to OpenWrt. 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 Bunny and publish its new DS record. The cutover plan walks you through each step.
