Why use OnlyDNS instead of Google Cloud DNS?

OnlyDNS is a dedicated, cloud-agnostic authoritative DNS provider that eliminates GCP console clutter, JSON service account key management, and vendor lock-in, while delivering rapid edge propagation (0.2–5s), native MCP AI tools, and RFC 2136 dynamic DNS.

How does OnlyDNS improve multi-cloud resilience?

By keeping your authoritative DNS independent of Google Cloud infrastructure, your domain routing remains 100% operational even during regional or global GCP control plane outages.

Why Decouple Your DNS from Google Cloud

Hosting DNS inside GCP ties your mission-critical routing to a single cloud provider's identity and billing systems. OnlyDNS provides lightweight, dedicated DNS infrastructure engineered for modern developers.

Google Cloud DNS Limitations

Service account key overhead: Requires managing GCP IAM roles, JSON key files, and OAuth2 token exchanges just for basic DNS automation.
Console & API complexity: Heavy gcloud SDK dependencies and complex change batching requests slow down development cycles.
Single point of cloud failure: GCP-wide identity or billing outages can impact your external domain routing.
No native MCP agent support: Lacks standardized Model Context Protocol tools for AI coding assistants.

The OnlyDNS Advantage

Instant developer authentication: Standard HTTP Bearer tokens and HMAC TSIG keys generated in seconds.
Multi-cloud routing independence: Safely route traffic across AWS, GCP, Azure, Bare Metal, and edge platforms without cloud lock-in.
Rapid edge propagation: Changes sync globally across 23 Tier 1 Anycast PoPs in 0.2 to 5 seconds.
Official Model Context Protocol (MCP): Native tool calling for Claude Desktop, Cursor, and autonomous agent loops.

Migrating from Google Cloud DNS in 3 Steps

Export your GCP managed zones and switch to OnlyDNS with zero downtime.

Export GCP Zone via gcloud CLI

Export your Google Cloud DNS managed zone to a standard BIND zone file:

gcloud dns record-sets export zone.txt \
  --zone=my-zone --zone-file-format

Import Zone into OnlyDNS

Import your zone instantly using the OnlyDNS CLI or web portal:

onlydns zones import --file zone.txt

Update Nameserver Delegation

Point your domain registrar to OnlyDNS nameservers (ns1.onlydns.com and ns2.onlydns.us).
