Hi,
Seem to be a good change.

Hi all,
We have proofread the DCCP spec in detail for AUTH48, and have found a
number of technical nits. There was one thing that I wanted to mention
explicitly before AUTH48 ends.
We propose to change the default value of the Allow Short Sequence
Numbers feature to 0.
Recap: DCCP sequence numbers can be either long (48 bits) or short (24
bits). Short sequence numbers save header space, but leave connections
at greater risk for attack (and sequence number wrapping).
It seems like stack implementations should default to long sequence
numbers, since this is safe, and allow short sequence numbers only if a
connection is known to be data-limited. We can indicate this in the
spec by setting Allow Short Seqnos's default to 0.
Quick comments OK.
Thanks,
Eddie
