IP addresses and routing
"This post is only about IPv4 because I’ve still never used IPv6."<p>IPv6 almost seems to be the networking equivalent of DAB radio at this point. A once futuristic tech that grew old in the tooth waiting for its moment.<p>At least IPv6 is getting developed and it's is easier to update than DAB, so one can hope that one day in the far future it becomes usable to people like me.
