Technical Information About DNS Records
Domain Name System (DNS) records are essential components that translate human-readable domain names into machine-readable IP addresses and other routing information. Understanding different record types helps you manage your domain infrastructure effectively.
DNS Record Types Explained
- A Record: Maps domain names to IPv4 addresses, directing users to your website's server location
- AAAA Record: Similar to A records but maps domains to IPv6 addresses for next-generation internet protocol
- MX Record: Specifies mail exchange servers responsible for receiving emails sent to your domain
- CNAME Record: Creates aliases for domain names, allowing one domain to reference another without changing IP address
- TXT Record: Stores text-based information used for domain verification, email authentication (SPF/DKIM/DMARC), and security purposes
- NS Record: Identifies authoritative nameservers that control DNS resolution for your domain
- SOA Record: Contains start of authority information including primary nameserver and domain administrator contact details
- SRV Record: Specifies service location records for applications requiring specific port and protocol information
