For the Cloudflare folks hanging around:

Please, please, please add some basic "features" (like Google does) that will help when troubleshooting resolution!

For example, the following will show the unicast IP address of the server you're hitting when using 8.8.8.8:

  $ dig @8.8.8.8 txt o-o.myaddr.l.google.com. +short
Additionally, with one other DNS query, we can get a list of what netblocks are being used (for Google Public DNS) in what datacenters/locations:

  $ dig @8.8.8.8 txt locations.publicdns.goog. +short
(This same info, along with a small shell script to format it nicely, is available on their web site [0] as well.)

I think i have questions to Google:

  [user@v-fed-1 ~]$ dig txt o-o.myaddr.l.google.com @8.8.8.8 +short
  "74.125.46.8"
  "edns0-client-subnet 92.223.114.166/32"
  [user@v-fed-1 ~]$ dig txt o-o.myaddr.l.google.com @8.8.8.8 +short
  "74.125.46.11"
  "edns0-client-subnet 176.36.247.0/24"
  [user@v-fed-1 ~]$ dig txt o-o.myaddr.l.google.com @8.8.8.8 +short
  "74.125.74.3"
  "edns0-client-subnet 94.181.44.185/32"
  [user@v-fed-1 ~]$ dig txt o-o.myaddr.l.google.com @8.8.8.8 +short
  "74.125.46.8"
  "edns0-client-subnet 92.223.114.166/32"
  [user@v-fed-1 ~]$ dig txt o-o.myaddr.l.google.com @8.8.8.8 +short
  "74.125.74.3"
  "edns0-client-subnet 94.181.44.185/32"

What is your question? I think we're seeing load balancing here.

Load balancing of ECS?
