Guides
Short, specific answers to the questions that come up before and after you buy a domain.
Length, spelling, endings, trademarks, and the tests a name should pass before you buy it.
How a name becomes an address, what resolvers and authoritative servers do, and why changes take time.
Each record type, what it is for, and the mistakes that break mail and websites.
How transfers actually work, EPP codes, and the 60-day lock.
What each ending signals, who can register what, and how renewal prices differ.
Grace period, redemption, and the fees nobody warns you about.
Pointing a domain at a host, the www question, and checking that it worked.
Certificates, who issues them, why they expire, and what the padlock does and does not mean.
What registries publish about you, what redaction hides, and when it does not apply.
A record that saves cleanly and changes nothing is usually a record in a zone nobody queries. Two lookups prove it.
The registrant verification notice looks exactly like phishing, and ignoring it suspends the domain. How to tell, in under a minute.
Moving nameservers moves the whole zone. The records you did not copy stop existing — and MX is the one people forget.
Letters and emails that look like renewal invoices, what they are actually selling, and the one lookup that settles it.
Renewal wrote a new file and the server is still handing out the old one. How to tell in one step, and the four usual causes.
Selector not found, no key for signature, record truncated — the DKIM failures that are a DNS problem, and the one that is not.
