# LightHouse
|
||||
|
||||
LightHouse is a DNS authoritative nameserver made in Go with ``github.com/miekg/dns`` library.
|
||||
|
||||
Records are stored in a MySQL Database and cached using REDIS.
|
||||
|
||||
This software is currently in development and NOT ready for production.
|
||||
|
||||
## What is working
|
||||
- Read records (stricts & wildcard) from MySQL
|
||||
- Read and write records (stricts & wildcard) in REDIS
|
||||
- Recursive wildcard for reverse DNS (IPv6 only)
|
||||
- Generate dynamic reverse DNS (IPv6 only)
|
||||
- Respond to all requested MySQL queries
|
||||
|
||||
## ToDo
|
||||
- Recursive wildcard for reverse DNS (IPv4 part)
|
||||
- Generate dynamic reverse DNS (IPv4 part)
|
||||
- XFR
|
||||
- DNSSEC
|
||||
- Unit tests
|
||||
- CI with auto packaging
|
||||
- Optimization
