Question # 2

The trace route was done from my home computer. the first was done to www.cuny.edu  and it's IP address is 128.228.38.47

the second trace was done to the website www.york.cuny.edu with IP address 198.61.16.7

Each of the lines in the trace route result represents a specific value. the first line represents the number of hops in the trace that were taken.the second,third and fourth line represented the time in milliseconds it took to return a value to the host requesting the information. the last and right most line represents the IP address and in some cases the name of the server where that hop landed.
