<p>For those that don't know this, if you want to know which cluster
you're hitting, you can run:</p>
<tt>$ dig o-o.myaddr.l.google.com -t txt +short @8.8.8.8</tt><tt><br>
</tt><tt>"172.253.192.142"</tt><tt><br>
</tt><tt>"edns0-client-subnet x.x.x.0/24"</tt><br>
<br>
<p>That will return the ipv4/ipv6 address of the server that handled
your request. To get a list of what subnets map to which
locations (airport codes), you can run:<br>
</p>
<p><tt>$ dig -t TXT +short locations.publicdns.goog. @8.8.8.8</tt></p>
<p><tt>snip... "172.253.192.0/24 cbf ..snip</tt><br>
</p>
<p>cbf = Council Bluffs, IA</p>

And, more importantly, 'Google DNS' -- specifically Google
customer resolver DNS, the stuff they provide at 8.8.8.8 -- is
generally IP anycast, so depending on your geographic and network
location, you are hitting different servers when you go to that
IP.<br>
