Frequently Asked Questions

A DNS record maps domain names to data. A records point to IPv4, AAAA to IPv6, CNAME to other names, MX to mail servers, TXT for verification/SPF. Records live in DNS zone files.

An A record maps a hostname to an IPv4 address. Example: example.com → 93.184.216.34. Most basic DNS record type. Use AAAA for IPv6 addresses.

CNAME (Canonical Name) creates an alias. www.example.com CNAME example.com means www resolves to whatever example.com resolves to. Can't coexist with other record types at same name.

MX records direct email to mail servers. They have priority (lower = preferred). MX 10 mail1.example.com means try mail1 first. MX 20 mail2 is backup if mail1 fails.

TXT records store text data: SPF (email authentication), DKIM (email signing), domain verification (Google, Let's Encrypt), and arbitrary data. 255 char limit per string.

Time To Live (TTL) in seconds tells resolvers how long to cache. Lower TTL = faster propagation but more DNS queries. Typical: 3600 (1 hour) to 86400 (1 day).

BIND format is standard zone file syntax. Includes SOA (Start of Authority), NS records, then other records. Used by BIND, PowerDNS, and as import format for many providers.

SRV specifies server locations for services. Format: _service._protocol.name priority weight port target. Used by SIP, XMPP, LDAP. Example: _sip._tcp.example.com.

NS records delegate a zone to nameservers. At zone apex, they define authoritative nameservers. Can also delegate subdomains to different nameservers.

SPF (Sender Policy Framework) TXT record lists authorized mail senders. Example: 'v=spf1 include:_spf.google.com ~all' allows Google to send mail for your domain.
