Note, there is a type for IP addresses, done like: ip"127.0.0.1" (should
also work for IPv6) or:
gen_ip() = IPv4(rand(0:256^4-1)) #not sure why you excluded 0 in 1:255
(might want to exclude some IPs but not as much as you did?), or used
global.

Generally global is bad form, and I'm not sure, but it might have something
to do with @async not working, as I guess it's not "thread-safe" or
related..
