This looks great!

Trying to run on a Mac however and getting a coproc: command not found error in the script:

➜  ~ ./asn 8.8.8.8

Any ideas?

Ok, it looks like it has something to do with the bash version in MacOS not being up to date (as MacOS has moved to zsh as the main shell).

➜  ~ bash --version
GNU bash, version 3.2.57(1)-release (x86_64-apple-darwin19)

Installing an updated version via brew install bash seems to have resolved it.

➜  ~ /usr/local/bin/bash --version
GNU bash, version 5.0.18(1)-release (x86_64-apple-darwin19.5.0)

Yeah, I heard Apple did something crazy with licensing that forced MacOS' official Bash version to 3. Although I wrote it in the README that Bash v4+ is required (precisely beacuse of asynchronous path tracing using coproc), I may indeed just add a warning during prerequisite checks that helps the user to figure out the problem right away. Will keep this open until I do.

Thanks for your feedback!
