A good answer is a good start.

Registration and hosting are separate services. Point the name to existing hosting or choose a plan for your website.

Configure DNS after registration completes. Cached records across the internet may delay when a new destination becomes visible.

Some extensions have premium renewal rates; others differ only at acquisition. Check both amounts for the exact domain.

Domain registration and trademark rights are separate. Review relevant name and trademark rights before commercial use.

A wildcard typically covers one level of subdomains. Check the SAN list for the root name and deeper levels.

Review HTTPS redirects, the certificate chain and mixed-content links. Plan renewal before the certificate expires.

A new registration claims an available name. An aftermarket domain is acquired from an existing owner with different pricing and steps.

Confirm seller authority, domain status, transfer conditions and the secure method used to complete the transaction.
