PLEASE HELP HOW DO I COMPLETE THIS ON A MAC COMPUTER. PLEASE HELP STEP BY STEP FOR VISUALIZATION AND UNDERSTANDING.

NSLookup

Figure out how to use the command:

Get an IP address from a domain. $(2$pts$)$

Get a domain from an IP address $($reverse lookup$)(2$pts$)$

Explain what a non$-$authoritative answer means $(1$pt$)$

Explain how to buy your own domain. Or just show me a domain you've bought. $(1$pt$)$

Tell me the steps $$ that the client lookup in the DNS $$ system goes through. $(2$pts$)$

Demonstrate how to find out who owns a domain. Use ICANN, not some other service, as ICANN provides the most information.

$(2$pts$)$

Ping

Figure out how to use the ping command. $(1$pt$)$

Pick a server to ping. Not a local one, but a server further away. $(1$pt$)$

Figure out how to redirect output from a command to a file. $(1$pt$)$

Run ping a really long time and capture the output. At least an hour. Maybe a day. $(5$pts$)$

Create a graph of the ping times. If you use the grep tool and regular expressions you can filter out the "extra" and just leave the

timings. However it is probably easier just to use search and replace in Excel. I don't want a histogram. Just graph the ping times

for each ping. $(5$pts$)$

Note that not all servers will respond to a ping request. Bonus points $($no for real, I will add points to grades$)$ to anyone who can tell

why that is$.$ Also, if there is traffic congestion, ping packets will be one of the first to get dropped.

Totally random suggestion to get side$-$tracked with:

If you are on Linux or Mac, you can use

to filter your ping commands so that only the timing is left over. Grep $$ is a tool used to

quickly filter text based on regular expressions.
