Technical Summary
A number of IPv4 options have become obsolete in practice, but have
never been formally deprecated. This document deprecates such IPv4
options, thus cleaning up the corresponding IANA registry, and
serving as a basis for providing advice about the filtering of
packets containing these options. Additionally, it requests that the
status of the corresponding RFCs be changed to "Historic".

This document does not modify the security properties of the IPv4 Options being deprecated. However, formally deprecating these options serves as a basis for e.g. providing advice about filtering packets containing these options (as in [I-D.ietf-opsec-ip-options-filtering]).
