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.com` and `parking.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. 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. - **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) 1. **Import Selection**: - **Option 1 (Zone File Upload)**: Drag & drop standard BIND `.zone`, `.txt`, or `.csv` files 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. 2. **Visual Review & Syntax Validation**: Interactive staging table validating IPv4/IPv6 syntax, MX priorities, and TXT quotes with real-time error prevention. 3. **Staged Sync & Nameserver Delegation**: Records stage across all 23 global Anycast nodes instantly. Update registrar nameservers to `ns1.onlydns.com` and `ns2.onlydns.us` with live delegation tracking. ### Method B: Terminal CLI Migration ```bash # 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.
