    abstract =  {The goal of this memo is to create a new IANA registry (called the MPLS First Nibble registry) for the first nibble (4-bit field) immediately following an MPLS label stack. The memo offers a rationale for such a registry, describes how the registry should be managed, and provides some initial entries. Furthermore, this memo sets out some documentation requirements for registering new values. Finally, it provides some recommendations that makes processing MPLS packets easier and more robust. There is an important caveat on the use of this registry versus the IP version number registry. This memo, if published, would update {[}RFC4928{]} and {[}RFC8469{]}.},
