Sistem Terdistribusi

Question (Exercise 13.9)
Which other name server addresses do DNS name servers hold by default, and why?

Answer :

A DNS name server holds the addresses of one or more root servers, so that all parts of the name space can be reached. It stores the addresses of servers storing subdomains (thus a server for qmw.ac.uk stores addresses of servers for dcs.qmw.ac.uk). Thirdly, it is often convenient for it to store the addresses of servers storing its parent domain (thus a server in dcs.qmw.ac.uk  knows the addresses of servers storing qmw.ac.uk).
