===Best Current Practice===
The [[Best Current Practice]] subseries collects administrative documents and other texts which are considered as official rules and not only ''informational'', but which do not affect ''over the wire data''. The border between standards track and BCP is often unclear. If a document only affects the Internet Standards Process, like BCP 9,<ref>{{cite IETF |title=The Internet Standards Process – Revision 3 |bcp=9 |last=Bradner |first=Scott O. |author-link=Scott Bradner |date=October 1996 |publisher=[[IETF]] |access-date=October 25, 2017 }}</ref> or IETF administration, it is clearly a BCP. If it only defines rules and regulations for [[Internet Assigned Numbers Authority]] (IANA) registries it is less clear; most of these documents are BCPs, but some are on the standards track.

The BCP series also covers technical recommendations for how to practice Internet standards; for instance, the recommendation to use source filtering to make [[DoS attack]]s more difficult ({{IETF RFC|2827|link=no}}: "''Network Ingress Filtering: Defeating Denial of Service Attacks which employ IP Source Address Spoofing''") is [//tools.ietf.org/html/bcp38 BCP 38].
