What is an A Record?

DNS record type that maps a domain name to an IPv4 address.

Detailed Explanation

The A (Address) record is the most fundamental DNS record type. It creates a direct mapping from a hostname to a 32-bit IPv4 address. When you visit a website, your browser looks up the A record to find the server's IP address. A single domain can have multiple A records for load balancing or redundancy.

Examples

  • example.com A 93.184.216.34
  • www.example.com A 192.0.2.1
  • Multiple A records: web.example.com → 203.0.113.1, 203.0.113.2
