Return to DNS, TCP/IP Glossary, DHCP Glossary

• Provide a DNS glossary of the top 40 DNS concepts sorted by the most commonly used. For each concept include a brief description, the related IETF RFC number and the URL for the IETF official documentation, along with the URL for the developer.mozilla.org mdn webdocs documentation, along with the URL for the DreamHost.com documentation, along with the URL for the Microsoft Official documentation. Answer using MediaWiki format.

Creating a comprehensive glossary for the top 40 Domain Name System (DNS) concepts requires highlighting core functionalities, record types, operational principles, and related protocols of DNS. This response provides structured information in MediaWiki format, focusing on key DNS concepts with descriptions, related IETF RFC numbers, and links to the IETF official documentation, MDN Web Docs, DreamHost documentation, and Microsoft official documentation.

Please note that the direct links to DreamHost and Microsoft official documentation for specific DNS concepts may not always be available or directly relevant; thus, generic documentation pages that broadly cover DNS concepts or related networking features are provided where specific concept documentation is not available.
