| Configuration | Description |
|---|---|
| NameServers | name servers the DNS query forward to, format: address:port, default port is 53 |
| Listen | UDP Listen address:port, default: 0.0.0.0:53 |
| StatsFile | stats file, absolute path |
| StatsPeriod | ddns dump stats periodically(seconds) |
| Backends | redis server, ddns will log to backend by Backends[crc32(domain)%len(Backends)] |
| ConnectTimeout | timeout for connecting to redis server, Millisecond |
| ReadTimeout | timeout for read/write to redis server, Millisecond |
| ChanNum | concurrency numbers for writing to redis |
| PoolNum | redis connection pool, must little greater than ChanNum |
| Debug | verbose output |
