OnlyDNS
oficialDNS Anycast autoritativo projetado para agentes de IA autônomos
O que você pode fazer com OnlyDNS MCP?
- List and inspect zones — Ask the assistant to list all domains on the account and pull every record for a given zone.
- Add or replace records — Have it append a new record (e.g. an A record for
agent-01) or atomically replace a zone's record set. - Delete records — Remove records matching a specific name and type from a domain.
- Check DNSSEC status — Retrieve a domain's DNSSEC activation state and DS key details.
- Configure TSIG keys — Create HMAC TSIG keys and scope RFC 2136 update permissions to a subdomain like
_acme-challenge.

8. Free Domain Parking & Zero-Trust Email Defense
OnlyDNS provides a 100% free, zero-configuration authoritative domain parking service designed for defensive domain registrations, typo squat protection, and inactive portfolio domains.
- Nameservers:
parking.onlydns.comandparking.onlydns.us - Cost: 100% Free, no account or payment required.
- Automated Anti-Spoofing Records:
- RFC 7505 Null MX: Publishes
IN MX 0 .signaling to all mail transfer agents that the domain does not accept email. - Strict SPF Record: Publishes
IN TXT "v=spf1 -all"asserting that zero IP addresses are authorized to send outbound email. - Strict DMARC Policy: Publishes
_dmarc.<domain> IN TXT "v=DMARC1; p=reject; sp=reject; adkim=s; aspf=s;"instructing email receivers to reject any spoofed email pretending to come from the apex domain or subdomains.
- RFC 7505 Null MX: Publishes
- Web Presence: Renders a clean, lightweight landing page stating the domain is registered and parked with no paid advertising (zero pay-per-click ads or tracking scripts).
9. Zero-Downtime DNS Migration (Web Portal & CLI)
OnlyDNS provides two zero-downtime migration workflows to transfer DNS records without dropped queries or broken email:
Method A: Web Portal Migration (3-Step Frictionless UI)
- Import Selection:
- Option 1 (Zone File Upload): Drag & drop standard BIND
.zone,.txt, or.csvfiles from Cloudflare, Route 53, GoDaddy, cPanel, or Plesk. - Option 2 (1-Click Smart DNS Auto-Discovery): Enter domain name; OnlyDNS automatically queries and discovers live A, AAAA, MX, SPF, DKIM, DMARC, and CNAME records without requiring a manual zone file export.
- Option 1 (Zone File Upload): Drag & drop standard BIND
- Visual Review & Syntax Validation: Interactive staging table validating IPv4/IPv6 syntax, MX priorities, and TXT quotes with real-time error prevention.
- Staged Sync & Nameserver Delegation: Records stage across all 23 global Anycast nodes instantly. Update registrar nameservers to
ns1.onlydns.comandns2.onlydns.uswith live delegation tracking.
Method B: Terminal CLI Migration
# 1. Install CLI
npm install -g @onlydns/cli
# 2. Authenticate
onlydns config set-key odn_live_your_key_here
# 3. Direct BIND zone file import
onlydns zone import example.com ./example.com.zone
# OR run automated DNS scanner import
onlydns zone scan example.com --import
# 4. Verify staged records
onlydns records list example.com
10. Automated SSL/TLS Certificates (RFC 2136 / TSIG ACME Hub)
OnlyDNS supports standards-compliant Dynamic DNS updates (RFC 2136) authenticated with HMAC-SHA256 TSIG keys (RFC 2845), enabling automated wildcard SSL/TLS certificate issuance across all major ACME clients and zero public port requirements.
- Master How-To Hub: https://www.onlydns.com/howto/rfc2136-acme
- Standard Nameserver:
ns1.onlydns.com(Port 53 UDP/TCP) - Algorithm:
HMAC-SHA256(IETF algorithm 163) - Propagation Speed: Rapid synchronization across all 23 global Anycast edge PoPs (typically 0.2 to 5 seconds).
Supported Client Guides & Quick Configurations:
