FAQ
What is a DNS record?
DNS is the internet’s phone book: it turns a domain name into addresses and information. Each record has a type: A (IPv4 address), AAAA (IPv6), CNAME (alias), MX (mail servers), NS (name servers), TXT (text: SPF, verifications), SOA (authority), CAA (allowed certificate authorities).
What does TTL mean?
TTL (Time To Live) is how long, in seconds, a resolver keeps the answer in memory. A TTL of 3600 means a change can take up to an hour to show. Lower it to 300 the day before a change.
What is DNSSEC?
DNSSEC signs DNS answers so attackers cannot forge them. A signed domain publishes keys (DNSKEY) and a fingerprint at its extension (DS). The tool shows whether the chain is valid.
