Resolver seems to be out in the ocean
Is this a first-class cabin? I suggest a first-class cabin
.COM gave resolver has a list of authoritative name servers? But how?
Resolver doesn't understand exactly how he got on this boat
How could the .COM TLD server point
me to the authoritative name servers?
How did it find the ones for dnsimple?
dnsimple is a special thing, but still, how did he do it?
How could he make the connection?
There are so many .COM domains!
Blue cat solves the puzzle one more time. Domain registrars are the key
That blue cat is really everywhere, doesn't he?
Easy! With the help of the Domain
So that how a domain registrar looks like
Make sense for it to be a folder because it keeps a tab on domains
When a domain is purchased, the
domain registrar reserves the name…
The domain registrar informs the TLDs about new domain registrations
It is a push model instead of a pull?
nd communicates to the TLD
registry the authoritative name servers.
It seems that the boat finally anchored somewhere in land
But where in the DNS world are we?
We have arrived!
Uh oh. Is this customs or something?
This new land is not really friendly now
Resolver does not seem to have a DNS visa in order
We were not told that we needed a visa when we boarded the DNS boat
Oh! I’ll be quick. I have no intention of
staying here. I am looking for
Not friendly at all
Yes, but what type of papers?
Resolver explains that he didn't go through all this DNS road trip for nothing
It seems that it has been forever since we got that original request for dnsimple
Oh boy! The only thing I have is a
request for dnsimple.com. The .COM
TLD told me that ns1.dnsimple.com
could tell me where I could locate the IP
Will resolver have to fill a visa application?
The star on his chest really makes him look like an DNS authority
Well, in that case…
Well, that took a different turn! ns1.dnsimple.com is the Authoritative Name Server
Those glasses were definitely inspired by a character in Big Lebowski
I am ns1.dnsimple.com
The Authoritative Name Server can help the resolver finding out the IP address for DNSimple
I love when people can help each other
And I can provide you with that answer!
Authoritative Name Servers are not named after Star Wars characters. And they should
They are four and they are mighty
Currently there are 4 of us that
know how to resolve any domain
managed by dnsimple.com
Authoritative Name Servers are the basic authority for a domain
IP addresses, mail records, Authoritative Name Servers know everything about a domain
We provide answers to DNS queries:
Web site IP address…
Mail IP address…
We are the
on this stuff.
Oh, Authoritative Name Servers don't cache the values.
I am having double thoughts for my birthday then
No cached values. Not asking
someone else. Only the real deal.
Any Authoritative Name Servers can respond to any query for your domain
That makes them redundant. Which is good thing on the internet
You see, usually there is more than
one name server attached to any
Authoritative Name Servers are totally ready to take your calls. No stand by. No elevator music
Pretty important role the one of an Authoritative Name Server
You, the resolver, you are given this list
in some unknown order.
You might query the first name server in
We have to
Yay! For distributed Authoritative Name Servers
The globe. I never know what's the best continent to show on it
And the DNS zone availability is
Because there is more of us, the
work load is better distributed.
Authoritative Name Servers have feelings and can breakdown at anytime
Keeping it DNS friendly, don't break Authoritative Name Servers feelings
Especially in case of a failure!
WHOIS queries help you figure out who are the Authoritative Name Servers for your domain
You can also discover other stuff. Like the owner of the domain and contact information
So if you want to know who are the
authoritative name servers for your
domain, run a WHOIS query.
And there are a few websites
that do this as well.
Your computer might already
have the WHOIS tool installed.
The IP address for dnsimple.com is finally discovered
Authoritative tells you a bunch of stuff and then, BAM, they give you the IP address, just like that
So here you go: 126.96.36.199
Resolver is in awe! Is that it? Did it make it? He cannot believe it
That face when you didn't expect it
The Authoritative Name Server is nice and repeats the IP address for dnsimple.com
He does not mind repeating
dnsimple.com IP address is:
Resolver has everything that he needs now
Finally, we can go back home?
Uh, no. Thanks!
Resolver uses his mighty memory to store the IP address
I hope he's not using the cloud to store his things
I guess I’ll save that.
Saving dnsimple IP address
5 seconds remaning
Blue cat celebrates that resolver got what he needed
Blue cat is a celebration guy, you can tell
The resolver finally got the answer he
was looking for! Hurray for the
Authoritative name server!
Road Trip! Let's do this!
One more DNS road trip. Make it happen
Time to go home!
Will the resolver make it back home in time?
Find out in the next episode of
how DNS works.
