| 1 | The tinydns data.cdb format is subject to change. If you want to write |
| 2 | code that relies on something here, let me know. |
| 3 | |
| 4 | Keys starting with the two bytes \000\045 are locations. The rest of the |
| 5 | key is an IP prefix, normally between 0 and 4 bytes long. The data is a |
| 6 | 2-byte location. |
| 7 | |
| 8 | Other keys are owner names for DNS records. The data begins with a |
| 9 | header in the following format: |
| 10 | |
| 11 | * a 2-byte type; |
| 12 | * either \075, or \076 with a 2-byte location; |
| 13 | * a 4-byte TTL; |
| 14 | * an 8-byte timestamp. |
| 15 | |
| 16 | (Exception: Wildcard records replace \075 with \052 and \076 with \053; |
| 17 | also, the owner name omits the wildcard.) The data continues in a |
| 18 | type-specific format: |
| 19 | |
| 20 | * SOA: first domain name, second domain name, 20-byte miscellany. |
| 21 | * NS or PTR or CNAME: domain name. |
| 22 | * MX: 2-byte preference, domain name. |
| 23 | * Other types: no special structure. |
| 24 | |
| 25 | Domain names, types, and numbers are in DNS packet format. |
