2. Mapping Domain Names to Addresses Name to address translation is performed by a program called a Name server The client program is called a Name resolver A Name resolver may need to contact several Name servers to translate a name to an address The Domain Name System DNS servers are organized in a somewhat hierarchical fashion A single server often holds names for a single network which is connected to a root DNS server usually maintained by an ISP Domain Name Resolution The domain name system can be used by contacting the name servers one at a time or by asking the domain name system to do the complete name translation The client makes a query containing the name the type of answer required and a code specifying whether the domain name system should do the entire name translation or simply return the address of the next DNS server if the server receiving the query cannot resolve the name When a DNS server receives a query it checks to see if the name is in its subdomain If it is the server translates the name and appends the answer to the query and sends it back to the client If the DNS server cannot translate the name it determines what type of name resolution the client requested A complete translation is called recursive resolution and requires the server to contact other DNS servers until the name is resolved Iterative resolution specifies that if the DNS server cannot supply an answer it returns the address of the
