The command is only:
dig +short TXT google-public-dns-a.google.com
by the way, the "http://xkcd..." part is the response, but since @asdafa didn't put \n\n after the command, it's appearing at the same line.
Maybe a stupid question, but is it monetized somehow? I mean DNS servers. After all, it's a pretty heavy load… I still don't really understand what is (is known to be) monetizable and what isn't.
The funny thing is I had to blackhole 8.8.8.8 on my home router earlier this week because of a change in the Netflix app on the Roku. Why won't people just take my money?
What's the 8.8.8.8 server?
Do NOT forget 8.8.4.4!

I thought Google's core product was allowing "ping -t google.com" ICMP traffic to be the central monitor of my network connectivity and latency to the internet.
Heck, I even have it aliased as "pg" on all my systems.
