Do a DNS query. You don't even have to randomise the id number, just

"dns.google" is probably an excellent target.
If you wanted something generic, what about a PTR query for something
in 10/8, directed at the AS112 project? That's pretty much the
sinkhole that expects that kind of unwanted traffic...
I bet that within a gnat's crotchet you'll find systemd has adopted
that as a special "liveness" command or something. </snark>
Not a serious problem for you and me, who are operators that know how to
do this and understand it well.
For Jane, down the road, who doesn't care and just wants her MTV, she's
not interested in what a DNS query is. All she is know is the
tech-support on the other end of the horn asked her to "ping 8.8.8.8".
