And, there's this one I happened to stumble across some years ago,
and looks like they're still up to it:
$ (for i in $(dig +short getfedora.org. AAAA); do sipcalc "$i" | sed  
-ne 's/^Expanded Address\t-  
\(\([0-9a-f]\{4\}:\)\{7\}[0-9a-f]\{4\}\)$/\1/p'; done) | sort -t: -k 5

2610:0028:3090:3001:dead:beef:cafe:fed3
2620:0052:0003:0001:dead:beef:cafe:fed6
2620:0052:0003:0001:dead:beef:cafe:fed7

$

Anyway, many such examples/collections to be found ... appropriate web
searching can find many such lists/collections/examples, etc.
