ok that’s amazing.

RFC1149 amazing.


Side note, am I missing something obvious where I can’t just have hardware
routers strip ICMP, pipe it separately, put 500 VMs behind 4 vLBs and let
the world ping the brains out of it?


I suspect that half the reason: "ping 8.8.8.8" (do not do this!) is used
is: "easy to remember 8.8.8.8"
and half is: "Well, that IP is well connected enough that you are
reasonably assured that: 'enough of the internet is up ....'" if it replies.

(maybe it's 75/25? or 80/20 not 5050... but you get my point)
