FAQPage Schema
How do I configure DNS-based wide-area discovery for nodes in cross-network deployments?

DNS-based wide-area discovery is configured by setting up DNS SRV and TXT records, allowing nodes residing in multiple networks or cloud regions to automatically locate each other. This enables seamless interconnections across different networks.

When do I need to use DNS SRV and TXT records for gateway discovery?

DNS SRV and TXT records for gateway discovery are needed when deploying nodes across different networks or cloud regions. They provide an automated mechanism for wide-area node discovery, bypassing the limitations of local network broadcasts.

What is the best way to enable cross-network node discovery for Crab Claw?

The best way to enable cross-network node discovery is applying DNS SRV and TXT records via an interactive CLI flow. This collects provider, domain, and zone information, applies changes, and verifies DNS propagation across WAN environments.

Can I use DNS setup for hybrid deployments where nodes live behind different networks?

DNS setup supports hybrid deployments where nodes live behind different networks or cloud regions. It satisfies configuration and verification requirements for DNS provider setup, domain, zone, and record verification to ensure cross-network reachability.

What are the limitations of using DNS records for cross-network node discovery?

Cross-network node discovery using DNS records requires proper DNS provider setup and successful DNS propagation verification. It is specifically designed for wide-area deployments and does not apply to local network discovery scenarios.

Why does automated node discovery require DNS provider and zone configuration?

Automated node discovery requires DNS provider and zone configuration to correctly route SRV and TXT records. This setup defines where gateway discovery information is published, ensuring nodes across multiple networks can reliably query and locate each other.
