Understanding Standard DNS Record Types
Every internet service relies on specific DNS resource record formats defined by IETF RFC standards. Here is an overview of standard record types and their applications:
Maps a domain name to a 32-bit IPv4 address (e.g. 93.184.216.34). Essential for pointing web traffic to hosting servers.
Maps a domain name to a 128-bit IPv6 address (e.g. 2606:2800:220:1:248:1893:25c8:1946) for next-generation internet routing.
Canonical Name. Aliases a subdomain to another domain or CDN distribution (e.g. shop.example.com → myshop.shopify.com).
Mail Exchange. Directs incoming emails to mail servers with priority weights (e.g. 10 aspmx.l.google.com).
Stores arbitrary text data. Primarily used for email anti-spoofing policies (SPF, DKIM, DMARC) and domain ownership verification.
Name Server. Delegates a DNS zone to authoritative nameservers responsible for resolving records for that domain.
DNS Lookup FAQs
What is a DNS Record Lookup?↓
A DNS lookup queries recursive and authoritative nameservers to fetch the resource records associated with a domain name, such as its IPv4 address (A record), IPv6 address (AAAA record), mail servers (MX records), or verification records (TXT records).
How do A records and CNAME records differ?↓
An A record maps a hostname directly to an IPv4 address (e.g. 192.0.2.1). A CNAME (Canonical Name) record aliases one domain name to another domain name (e.g. www.example.com points to example.com), requiring a secondary DNS query to resolve the final IP address.
What is DNS TTL (Time to Live)?↓
TTL is a 32-bit integer indicating the number of seconds a DNS record should remain cached in recursive resolver and browser caches before querying the authoritative nameserver again. Lower TTLs (300s) are ideal for migration, while higher TTLs (86400s) reduce DNS lookup queries.
What are TXT records used for in modern web hosting?↓
TXT records hold human and machine-readable text data. Today, they are predominantly used for email authentication protocols (SPF, DKIM, and DMARC) and domain ownership verification for SSL certificate providers, Google Search Console, and Microsoft 365.
