# Éric Vyncke, INT AD, comments for draft-ietf-shmoo-hackathon-07
CC @evyncke

Thank you for the work put into this document.

Please find below some non-blocking COMMENT points (but replies would be
appreciated even if only for my own education).

Special thanks to Valery Smyslov for the shepherd's detailed write-up including
the WG consensus *but* the justification of the intended status is missing.

I hope that this review helps to improve the document,

Regards,

-éric

## COMMENTS

### Timing of the WG docs

Like Alvaro wrote, it would have been nicer for the reviewer to have this
document published before RFC 9244 ;-)

### Section 3.1.1 report

`recently reported large DDoS attacks exceeded several Tbps` please provide an
informative reference to this report.

### Section 3.1.1 top-talkers

I am a little puzzled how an attack coming out of *two* top-talkers (and thanks
for using IPv6 examples :-) ) is a *distributed* DoS attack. Suggest to change
the prefix to something broader (e.g., two /48) rather than a host /128 prefix.

### Section 3.1.1 figure 1 e.g.

Is the use of "E.g.," in figures common ? or useful ? in figure 1 ?

As a side note, I am hard time to understand the figure 1: they are overloaded
and little explanations on the graphics are given.

### Section 3.1.5

The intro text is about DNS torture attack, but the DOTS example is about DNS
amplification attack, which appears as different attacks to me.

### Section 3.3.1

To be honest, the value of this section about ML escapes me ;-) (notably why
DOTS is helping here) but the example DOTS message would benefit of using
2001:db8::2/127 rather than the 2 /128 ;)

### Section 6

Like Murray, I also wonder why some reviews are labelled as IESG review ;-)
