In: Computer Science
a) You have installed the DNS server role on a
computer running Windows Server 2016
and in the process of configuring forward/reverse lookups. Explain
the difference
between “ping www.google.com” and “ping the IP address of Google
server at
172.217.167.68”. You may want to try both and observe any
differences. Your answer
should include your explanation, as well as screenshots.
When We ping www.google.com, it first request it's ip address from DNS(Domain Name Server). Then it request a packet from corresponding ip address. So total time taken will be equivalent to DNS query + packet fatching time.
But on the other hand if we ping 172.217.167.68, It directly request packet from given ip address. It does not need to send request to DNS as it already have ip address.So this way it takes less time.
Below is the proof :
You can clearly see that average time taken to fetch a packet from ww.google.com is higher than 172.217.167.68.
Like, if this helped.
