DNS Record Types Reference

DNS record types form the foundation of how domain names are resolved and used across the internet. Understanding these record types is essential for anyone managing domains, configuring email services, or working in IT infrastructure. Each record type serves a specific purpose — A records map domains to IPv4 addresses, MX records direct email traffic, CNAME records create aliases, and many others — all working together to ensure your domain functions correctly across different services.

This reference tool provides a comprehensive guide to all major DNS record types, including their structure, common use cases, and practical examples. You can explore the purpose of each record type, view sample values, and understand how they interact within your domain's DNS configuration. Whether you're setting up a website, configuring email servers, enabling secure connections via CAA records, or troubleshooting DNS issues, this tool gives you instant access to the exact information you need without having to search multiple resources.

DNS record management is crucial for domain operations, security, and reliability. Misconfigured records can prevent your website from loading, break email delivery, or leave your domain vulnerable to attacks. This reference is particularly useful for domain administrators, web developers, hosting support teams, and IT professionals who need to quickly verify record purposes, syntax, and TTL implications during configuration or troubleshooting.
