Explore detailed guides and answers regarding subdomain registration, RFC 1912 Anycast DNS, 1-click cloud hosting, and OwnPay checkout.
Subdomains & Identity
How does subdomain registration work on ZeroRegistrar?
ZeroRegistrar allows you to search and claim unique subdomain handles (e.g. yourname.love.cv or dev.yourname.cv) across our curated authoritative parent domains. Once registered, the subdomain belongs exclusively to your account, with automatic Anycast DNS edge routing and instant provisioning.
Subdomains & Identity
Can I transfer or renew my subdomain handle after registration?
Yes! Subdomain handles are registered on an annual basis with transparent catalog pricing and zero hidden markups. You can enable automatic renewals or manually renew from your Command Center before the expiration date.
DNS & RFC 1912
What DNS record types are supported and how is RFC 1912 enforced?
ZeroRegistrar provides a full authoritative DNS zone editor supporting A, AAAA, CNAME, TXT, MX, SRV, CAA, and NS records. We strictly enforce RFC 1912 compliance rules to ensure CNAME records do not co-exist with A or TXT records on the same node, preventing routing loops and zone corruption.
DNS & RFC 1912
How fast do DNS changes propagate across global edge nodes?
Our distributed Anycast DNS infrastructure propagates record additions, modifications, and deletions to edge nodes (NYC, Frankfurt, Tokyo, Singapore) in under 5 milliseconds with sub-second resolution times worldwide.
Hosting Integration
Can I connect my subdomain to Vercel, GitHub Pages, or Cloudflare?
Yes! We offer 1-click hosting presets for Vercel (76.76.21.21), GitHub Pages (185.199.108.153), Cloudflare Pages (cname.pages.dev), Netlify, Supabase, and Google Workspace MX. Simply select your provider from the DNS Zone Manager or follow our step-by-step setup guides.
Hosting Integration
Can I route traffic to a custom Linux VPS or dedicated server?
Absolutely. You can point your subdomain apex and wildcards to any public IPv4 (A record) or IPv6 (AAAA record) address, with custom TTL values ranging from 60 seconds to 24 hours.
Website Builder
How does the built-in Portfolio Website Builder work?
Every registered subdomain includes access to our Visual Site Studio and 10 responsive starter themes (Minimal Portfolio, Developer Showcase, Creative Agency, Dark Portfolio, Resume, Freelancer, etc.). You can customize your bio, skills, and projects, and publish live to our native edge in under 60 seconds.
Website Builder
Do portfolio websites include automated SSL certificates?
Yes! All portfolio websites published through ZeroRegistrar are automatically provisioned with free, auto-renewing SSL/TLS certificates with strict HTTPS redirection enabled by default.
Payments & Security
What payment methods are supported and how is checkout secured?
We integrate with the official OwnPay payment gateway supporting credit/debit cards (Visa, Mastercard, AMEX), Apple Pay, Google Pay, and cryptocurrency. All transactions are cryptographically verified using HMAC-SHA256 signatures with server-side price calculation and replay attack prevention.
Payments & Security
How do I enable Two-Factor Authentication (2FA) on my account?
You can enable standard TOTP Two-Factor Authentication from the Security Center. Scan the QR code with Google Authenticator, Authy, or 1Password to protect your account, domain delegation, and DNS zones.
Custom Domains & SSL
Can I map my own external domain (e.g. mybrand.com) to my subdomain portfolio?
Yes! You can map any external apex domain or custom subdomain from the Custom Domains manager. We provide automated TXT verification tokens and automated Let's Encrypt / Cloudflare SSL certificate provisioning.
