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
