1. Introduction
In the late 1980s, Van Jacobson, Steve McCanne, and others at the Network Research Group at Lawrence Berkeley National Laboratory developed the tcpdump program to capture and dissect network traces. The code to capture traffic, using low-level mechanisms in various operating systems, and to read and write network traces to a file was later put into a library named libpcap [LIBPCAP].¶
Other documents describe the original (legacy) file format used by tcpdump (PCAP, [I-D.ietf-opsawg-pcap]), as well as a revised file format [I-D.ietf-opsawg-pcapng], both of which are used by tcpdump and Wireshark [Wireshark].¶
Within those file formats each packet that is captured is indicated by a LinkType value. The LinkType value selects one of many hundred formats for metadata and Layer 2 encapsulation of the packet.¶
This document creates an IANA registry for LinkType values, establishing the IANA Considerations by which other uses of the PCAP-related formats may register new LinkType values.¶
2. IANA Considerations
2.1. PCAP Registry
IANA is requested to create a new registry group entitled "The PCAP Registry".¶
2.2. LinkType Registry
IANA is also requested to create a registry entitled "PCAP-related LinkType List" under The PCAP registry group (Section 2.1).¶
The registry has the following structure:¶
-
LinkType Value: Indicates the 16-bit unsigned integer assigned for this LinkType.¶
-
LinkType Name: Indicates the symbolic name for this LinkType. The name is prefixed with "LINKTYPE_" (i.e., LINKTYPE_something).¶
-
Change Controller: as per [RFC8126], Section 2.3¶
-
Description: Provides a very short description.¶
-
Reference: Indicates an authoritative document reference for the LinkType or a requester reference.¶
The policy allocation for the LinkType values is as follows:¶
-
Values from 0 to 65000 are allocated following an Expert Review policy (Section 4.5 of [RFC8126]). Values in the ranges 0-10, 50-51, and 98-301 are already assigned; values in the ranges 11-49 and 52-97 are reserved and must not be assigned.¶
-
Values from 65001 to 65535 are reserved for Experimental Use (Section 4.2 of [RFC8126]).¶
The initial version of the registry is provided in Section 2.2.1. In each case here, the reference should be set to [LINKTYPES] and the RFC number to be assigned to this document, which is not repeated each time.¶
The initial contents of the table are based upon the link-layer header type list maintained by libpcap, and published on [LINKTYPES]. The change controller for all initial entries that have no other reference is linktype@tcpdump.org.¶
LinkType values 147 to 162 named LINKTYPE_RESERVED_xx were originally reserved for Experimental/Private Use, and that use continues to be supported. However, new private use cases should use the values in the 65001-65535 range.¶
In general, Experimental Use values should never leak out of the entity that uses it. As the FCFS range is large and easily obtained, official values are recommended.¶
-
There is often an associated Data Link Type (DLT) value which is often identical in value, but not universally so. DLT values are associated with specific operating systems, and the numerical values for some of them are operating system specific, and are thus not subject to standardization.¶

2.2.2. Guidance for Designated Experts
When processing a request for an allocation, the Designated Experts will encourage the requester to provide a specification at a stable URL.¶
There is no requirement for a specification, but often review of the specification allows the Designated Expert to determine if the allocation actually is a duplicate of another specification.¶
When the contents of the link type can contain an IPv4 or IPv6 header, then the octets between the beginning of the link type and the IP header needs to be clearly specified.¶
Registrations for specifications that are not publicly available are acceptable. This includes specifications obtained via liaison agreements (such as to ITU-T, drafts, IEEE, etc.), those that may eventually be made public, or those for which no public document will be available.¶
The minimal requirement is to provide a contact for that link type.¶
For other documents, the Designated Expert will need use their judgement, or consult the OPSAWG or an Area Director.¶
3. Security Considerations
This document describes the IANA registration rules for the LinkType encapsulations. PCAP-related packet file formats use this value to determine what kind of headers precede network packet captures. Many of these formats can contain IPv4 and IPv6 packets. A system reading PCAP-related format captures can be subject to arbitrary inputs that may be controlled by malicious entities, so utmost caution is required.¶
Many LinkType formats include a "snapshot" length, which may be smaller than the actual packet. It is therefore very likely that trailing parts of a packet capture may be omitted, yet internal length fields in the packets will claim the packet is bigger than the capture. This leads to trivial buffer overreads, and systems interpreting the packets need to carefully scrutinize all attempts to read data from a capture.¶
4. Contributors
PCAP has been developed over three and half decades by a variety of developers, including: Bill Fenner, Denis Ovsienko, Francois-Xavier Le Bail, Fulvio Risso, Gerald Combs, Gianluca Varenni, Gisle Vanem, Hannes Gredler, Joerg Mayer, Michal Sekletar, Stephen Donnelly, Torsten Landschoff, and Jun-ichiro itojun Hagino.¶
PCAP was originally created at LBL by Steve McCanne, Craig Leres, and Van Jacobson.¶
