Launch-ready naming checklist
- Write the domain’s job, primary audience, and highest-risk encounter.
- Test every candidate by speech, delayed recall, lowercase display, email, and mobile screen.
- Compare full names across extensions instead of ranking TLDs in isolation.
- Search trademarks, company names, products, packages, social handles, and active counterpart domains.
- Review likely typos and lookalikes, then choose a proportionate defensive set.
- Confirm renewal price, security-service support, and future product flexibility.
- Select a preferred name, negotiated alternative, and viable fallback.
Domain acquisition checklist
- Define the exact assets and intended registrant entity.
- Verify current control with a transaction-specific, non-destructive method.
- Review registrar, statuses, dates, nameservers, DNSSEC, history, reputation, and prior disputes.
- Complete rights screening for the buyer’s intended use.
- Set opening, target, and walk-away ranges including transaction and migration cost.
- Use a written agreement and payment protection appropriate to the value.
- Preserve DNS, validate the transfer, restore locks, and update the inventory.
Critical-domain security checklist
- Correct legal registrant, dedicated account, role contacts, and phishing-resistant MFA.
- Recovery methods independent of the protected domain.
- Registrar lock; registry lock where risk and TLD support justify it.
- Dual approval for nameserver, transfer, DNSSEC, contact, and deletion changes.
- Auto-renewal, resilient payment, independent expiration alerts, and verified contacts.
- DNS provider access controls, scoped API tokens, logging, and external monitoring.
- DNSSEC monitoring when enabled; tested recovery and change runbooks.
- SPF, DKIM, DMARC, and deliberate policy for non-sending domains.
Migration checklist
- Inventory URLs, DNS, email, certificates, identity, APIs, webhooks, apps, and vendor allowlists.
- Secure and fully test the destination domain before public change.
- Map old URLs to the closest new equivalents and remove redirect chains.
- Configure new mail identities and authentication before announcing them.
- Communicate through trusted channels and warn about migration-themed phishing.
- Monitor DNS, TLS, redirects, crawl, email, authentication, transactions, and support.
- Keep the old domain registered and serving required redirects and aliases.
- Perform a post-launch review and update recovery documentation.
