Deploying NS1 in Mono Mode: A Lightweight DNS Powerhouse
When we talk about NS1, most people think of massive, globally distributed DNS filtering, traffic steering, and real-time analytics. But what about a mono (single-node) deployment? Whether youâre building a staging environment, a low-budget authoritative DNS server, or simply testing NS1âs powerful API-driven rules, running NS1 in mono mode is a viable, often overlooked option. ns1 mono
Because itâs mono, no peer addresses or consensus raft configuration is required. Load a zone via the API (single node means no replication lag):
curl -X PUT -H "X-NS1-Key: your-api-key" \ -d '"zone": "example.com", "ttl": 300' \ http://localhost:8080/v1/zones Add a record with a filter chain: Have you tried running NS1 in mono mode
â Not for production where downtime of a single node would cause outage. Assuming you have access to NS1âs onâprem software or a compatible openâcore build, a minimal ns1.conf might look like:
api: enabled: true listen: 127.0.0.1:8080 But what about a mono (single-node) deployment
curl -X PUT -H "X-NS1-Key: your-api-key" \ -d '"answers": ["answer": ["192.0.2.1"], "answer": ["192.0.2.2"]], "filters": ["weighted"]' \ http://localhost:8080/v1/zones/example.com/www The mono node will evaluate filters locally and return the best answer per request. | Feature | Mono behavior | |---------|----------------| | High availability | None | | Data replication | N/A | | Analytics aggregation | Local only | | DDoS protection | Single point of attack | | Rolling upgrades | Downtime required |
