Notes on configuring a hidden primary TinyDNS? server
Hidden Primary
Hidden Primary is a DNS configuration in which the primary DNS exports the authoritative data for the zone but all DNS lookups are handled by the secondary servers.
Reasons
- Convenient management of the zone file on a server you control
- Export DNS records to services like ZoneEdit? which don't support all types of records (like SRV)
Types of records
| Identifier | Records declared |
| # | none |
| Z | SOA |
| & | NS |
| . | NS, A, SOA |
| + | A |
| = | A, PTR |
| : | custom format: SRV, AAAA (IPv6?) |
| @ | MX |
