DNS RFC Repository
We maintain an up-to-date repository of DNS-related RFCs. To help quickly gather and browse documents of interest, we also give finer-grained labels under particular topics (e.g., DNSSEC, IDNA, DNS privacy) to each RFC.
This repository is expected to be updated once a month. It now comprises 42 RFCs under 42 labels, including:
- Documents subsequent to RFC 882
- DNS specification: namespace, name registration, DNS protocol
- DNS operation: functionalities and recommendations about running DNS services
- DNS security: security extensions, threat analysis, and proposed solutions
- DNS application: Internet functionalities that explicitly rely on the DNS (e.g., SPF, DANE)
- Obsoleted/deprecated versions of the above
Comments or suggestions are extremely welcome! Contact us if you find an RFC missing, mis-labeled, should be removed, or for any other feedback.
