g from: An attempt at suppressing ECS
silently getting ignored. That seemed worse. I do welcome better
alternatives. IMHO transitivity was enough of a corner case that
behaviour on rejecting it was not a terribly interesting detail.
All in all, I'm very gla
Just to add my ยข2 on this point:
In the last version of the draft that I wrote (and the one used for
most implementations), there was no MUST/SHOULD terminology, so it was
a little vague.
Reason we've added the truncation at the time is to save space. This
is DNS, where saving bytes is sometimes

Probably the safest, and then reissue a single query without ECS
instead of continuing
ss 0.0.0.0/0 to get it cached for many hosts).

It's just an example, I went for an IP address to save on words. COuld
consider mixing ::/0 (less typing in fact!) and 0.0.0.0/0 in various
examples.
