- [RFC5237][RFC7045]
- Note
In the Internet Protocol version 4 (IPv4) [RFC791] there is a field
called "Protocol" to identify the next level protocol. This is an 8
bit field. In Internet Protocol version 6 (IPv6) [RFC2460], this field
is called the "Next Header" field.
- Note
Values that are also IPv6 Extension Header Types should be listed in the
IPv6 Extension Header Types registry at [IANA registry ipv6-parameters].

In the Internet Protocol version 4 (IPv4) [RFC791] there is a field
called "Protocol" to identify the next level protocol. This is an 8
bit field. In Internet Protocol version 6 (IPv6) [RFC2460], this field
is called the "Next Header" field.
Values that are also IPv6 Extension Header Types should be listed in the
IPv6 Extension Header Types registry at [IANA registry ipv6-parameters].
