Note

The DSCP field within the DS field is capable of conveying 64 distinct
codepoints.  The codepoint space is divided into three pools for the
purpose of codepoint assignment and management: a pool of 32
codepoints (Pool 1) to be assigned by Standards Action as defined in
[RFC2434], a pool of 16 codepoints (Pool 2) to be reserved for
experimental or Local Use (EXP/LU) as defined in [RFC2434], and a pool
of 16 codepoints (Pool 3) which are initially available for experimental
or local use, but which should be preferentially utilized for
standardized assignments if Pool 1 is ever exhausted.  The pools are
defined in the following table (where 'x' refers to either '0' or
'1').
