Suppose that the local DNS server caches all information coming in from all root, TLD$,$ and authoritative DNS servers for $20$ time units. Assume also that the local cache is initially empty, that iterative DNS queries are always used, that DNS requests are just for name$-$to$-$IP$-$address translation, that $1$ time unit is needed for each server$-$to$-$server or host$-$toserver $($one way$)$ request or response, and that there is only one authoritative name server $($each$)$ for any $.$edu or $.$org domain. Consider the following DNS requests, made by the local host at the given times: t$=0,$ the local host requests that the name gaia.cs$.$umass.edu be resolved to an IP address. t$=1,$ the local host requests that the name icann.org be resolved to an IP address. t$=5,$ the local host requests that the name cs$.$umd.edu be resolved to an IP address. t$=10,$ the local host requests that the name gaia.cs$.$umass.edu be resolved to an IP address. t$=12,$ the local host requests that the name cs$.$mit.edu be resolved to an IP address. t$=16,$ the local host requests that the name ieee.org be resolved to an IP address. t$=19,$ the local host requests that the name cs$.$umd.edu be resolved to an IP address. t$=30,$ the local host requests that the name gaia.cs$.$umass.edu be resolved to an IP address. t$=44,$ the local host requests that the name gaia.cs$.$umass.edu be resolved to an IP address.
