NAME RESOLUTION SERVER AND PACKET TRANSMITTING DEVICE FOR CUSTOMIZING NAME RESOLUTION RESPONSES

摘要

PURPOSE: A name resolution server and a packet transmitting device for customizing name resolution responses are provided to enable the name resolution server to obtain user attribute information needed for customizing name resolution, and to precisely customize the name resolution based on the user attribute information without changing a current user environment. CONSTITUTION: A client(A1) and a DNS(Domain Name Server)(B1) are connected through the network(C1). The client transmits a DNS query message as a name resolution message to the DNS in order to resolve an IP(Internet Protocol) address corresponding to an FQDN(Fully Qualified Domain Name) of a node on the network. The DNS generates/transmits a name resolution response message to the client by responding to the DNS query message. The DNS server includes a query receiver(B11), a user information identifier(B12), a user information obtaining part(B13), a user information database(B14), a response making part(B15), a response database(B16), and a response transmitting part(B17).
