Technical Summary When experimenting with or extending protocols, it is often necessary to use some sort of protocol number or constant in order to actually test or experiment with the new function, even when testing in a closed environment. This document reserves some ranges of numbers for experimentation purposes in specific protocols where the need to support experimentation has been identified, and describes the numbers that have already been reserved by other documents. Working Group Summary This document is an individual submission. It has been reviewed by the INT area mailing list and updated based on discussion on that list. Protocol Quality This document was reviewed for the IESG by Margaret Wasserman and Jari Arkko. Note to RFC Editor Add the following paragraph at the beginning of the Security Considerations section: Production networks do not necessarily support the use of experimental code points in IP headers. The network scope of support for experimental values should be carefully evaluated before deploying any experiment across extended network domains, such as the public Internet. The potential to disrupt the stable operation of the network hosting the experiment through the use of unsupported experimental code points is a serious consideration when planning an experiment using such code points.
