Domain name and DNS guides for Canadian businesses
Guides to registration, renewal, transfer, expiry, privacy, .CA and .COM, DNS records, TTL, nameservers, propagation, mail routing, and safe DNS changes.
Domains & DNS
Understand the system, not just the setting.
Domains and DNS are small pieces of configuration with a large blast radius. This topic collects the practical material needed to choose a name, understand the records behind a website and email, and make changes without turning a routine update into an outage.

Domain registration checklist: what to check before registering
A domain registration checklist covering business control, extension rules, renewal, recovery, privacy, DNS, email planning, account security, and future transfer access.
DomainsDomain transfer status: why a transfer is pending or blocked
A domain transfer can be pending, locked, rejected, or waiting on authorization. Learn how registrar lock, authorization codes, eligibility, approval, expiry, and registry state affect transfer status.
DomainsDomain renewal cost: why renewal matters more than intro price
Compare domain renewal cost, registration price, transfer price, premium names, privacy, taxes, and add-ons before choosing a registrar based on a first-year discount.
DomainsDomain name expiry: what happens when renewal is missed?
Domain name expiry can interrupt DNS, websites, and email. Learn why recovery timing and fees vary by TLD and why you should act before assuming a domain can simply be re-registered.
DomainsDomain privacy Canada: what registration privacy does
Domain privacy affects what registration contact data is publicly displayed, but rules depend on the registry, TLD, registrant type, and current policy. Learn what it does and does not protect.
DomainsDomain ownership lookup: what public registration data can show
A domain ownership lookup may reveal registrar, nameservers, dates, status, and limited registration data, while registrant details may be redacted or privacy-protected.
DNSDNS propagation time: what is really happening?
DNS propagation time is mostly cache expiry across resolvers. Learn how TTL, authoritative DNS, local caches, and nameserver changes affect when users see new answers.
DNSChange nameservers safely without breaking email or subdomains
Changing nameservers moves authoritative DNS responsibility. Inventory the whole zone, reproduce records, test answers, and keep rollback details before changing delegation.
DNSDomain not resolving: how to find the broken DNS layer
When a domain is not resolving, check registration status, delegation, authoritative nameservers, zone records, DNSSEC, and recursive results in that order.
DNSTXT record setup for verification and email authentication
TXT records carry text used for service verification, SPF, DKIM-related data, DMARC, and other policies. Add the exact record at the correct hostname without overwriting unrelated values.
DNSDNS TTL explained: how cache time affects changes
DNS TTL tells recursive resolvers how long an answer may be cached. Learn how TTL affects planned migrations, query load, rollback timing, and why lowering it at the last second does not clear old caches.
