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)

# TinyDNS configuration

## Types of records

| Identifier | Records declared                           |
||
| #          | none                                       |
| Z          | SOA                                        |
| &          | NS                                         |
| .          | NS, A, SOA                                 |
| +          | A                                          |
| =          | A, PTR                                     |
| :          | custom format: SRV, AAAA (IPv6) |
| @          | MX                                         |
