IETF Standards Written by ISC Contributors

We have years of experience helping to keep the Internet running

ISC has a long history of contributing to, and implementing, open community standards.

The documents that specify and discuss current and developing standards for the Internet are called Requests for Comments, or RFCs. That name belies their role, as an RFC that has been assigned the status “standard” is the primary specification of an Internet standard. Other status codes include “draft standard,” “informational,” “historic,” “proposed standard,” or “experimental.” Many of the early RFC documents have status “unknown” because they come from the long-gone era when an RFC really was just a request for comments.

The Internet Engineering Task Force (IETF) has ultimate responsibility for RFC documents, and maintains a complete list of them in their online RFC Directory.

RFCs authored or co-authored by ISC affiliates

ISC employees and affiliates have written or contributed to over 90 RFCs, listed below.

RFCs pertaining to DNS

The Domain Name System protocols are more than 20 years old. Many of the older RFCs are obsolete, but there are still clients running software implementing the very oldest protocols.

In addition to the RFCs authored or co-authored by ISC contributors, you may find it interesting and/or useful to review all the IETF RFCs related to DNS, currently maintained by PowerDNS. FAQS.org also maintains a list of DNS Protocol Related Documents.

RFCs pertaining to DHCP

Because DHCP operates at several levels in the network and operating system stacks, the RFCs that pertain to it include some that do not even mention it. ISC has prepared a collection of DHCP references, which is included in every ISC DHCP distribution as doc/References.html.

One or more of the authors of each of these RFCs is or was affiliated with ISC in some capacity (e.g. employee, consultant, director):
