What can I help you with?
-
Root, I am trying to locate the IP address for the website dnsimple.com...
-
Do you know where I can find it?
-
Sorry resolver. I don't know where to find dnsimple.com.
-
But I can tell you where to find the .COM Top-level domain server!
-
-
But first, I'll store this information, so I don't have to ask the root again.
-
This root server is just one of the 13 root name servers that exist today.
-
Root servers sit at the top of the DNS hierarchy.
-
They are scattered around the globe and operated by 12 independent organisations.
-
They are named [letter].root-servers.net where [letter] ranges from A to M.
-
This doesn't mean that we have only 13 physical servers to support the whole internet!
-
Each organisation provides multiple physical servers distributed around the globe.
-
-
-
-
-
Not my kind of road trip
But we are now here...
-
-
How will the .COM TLD server help our friend the resolver?
Find out in the next episode of how DNS works.
