An 'A-record' (Address Record) is a type of DNS (Domain Name System) record that maps a domain name to its associated IPv4 address. It is fundamental for directing internet traffic to the correct server by translating human-readable domain names into numerical IP addresses that computers use to identify each other on the network.

Key Features

  • Maps domain names to IPv4 addresses
  • Essential for website accessibility and internet navigation
  • Part of DNS zone files and configurations
  • Supports fast resolution of domain queries
  • Can be configured with TTL (Time To Live) values for caching

Pros

  • Crucial for internet infrastructure and website operation
  • Simple to understand and implement
  • Widely supported across all DNS providers and platforms
  • Enables direct access to web servers via domain names

Cons

  • Limited to IPv4 addresses; does not support IPv6 (which requires AAAA records)
  • Misconfiguration can lead to website downtime or misdirection
  • Requires technical knowledge for proper setup and management
