"Cryptanalysis" of these X-Trace ?

Apparently the perp of the "cancel" attack on sci.crypt has moved
to another proxy. One recent cancel is copied below, followed by
the X-Trace field in some of >1200 similar cancels. How do we read
the X-Trace field ?

Note: last byte in X-Trace seems to be 0xF4

Repetition being the essence of Usenet:

This newsgroup, sci.crypt, is again under attack.
It received thousands systematic "cancel" messages.
When reading the group thru a server that honors these
cancels, the canceled messages do not show.

To survive this, my strategy is to read messages thru an
open nntp server that ignores the rogue cancels:
nntp://nntp.cquest.utoronto.ca/sci.crypt

and post messages (e.g. this one) using my usual ISP's
nntp server.

Given the ongoing counterstrike of REPOST, based on
earlier experience, I suggest killing these with
@news.noc.cabal.int   in the  Message-ID  header
and making sure to NOT include the word REPOST in the
title of a reply message.

An alternative would be to use an nntp server that filters
unwanted cancels and maybe the corresponding reposts; but
these are commercial.
