Note

The Mandatory Extension Header range in the ULE Next-Header registry is used to allocate integer values in the range 0-255 (decimal). These values are used to identify mandatory extension headers. The registered value corresponds to the 16-bit Type value for the mandatory extension header or the specified protocol.

The Optional Extension Header range in the ULE Next-Header registry is used to allocate integer values in the range 256-511 (decimal). These values are used to identify optional extension headers. The registered value corresponds to the 16-bit Type value that would be used for an optional extension header with a header length (H-LEN) of 1.

Note

The range 512-1535 is also assigned for Optional Extension Headers. IANA does not allocate numbers in this range. The values are derived from the combination of a registry entry in the range 256-511, and the corresponding H-LEN values specified in each registry entry RFC 4326.
