It is possible to realize an easy access control not requiring complicated setting of user access authority in each Web server or not requiring user authentication each time each Web server is accessed. A dedicated DNS server (52) for managing a domain name is arranged in a dedicated network (50). When a gateway (40) is an authenticated terminal according to the authentication by an authentication server (53) in the dedicated network (50), the IP address of the dedicated server (52) is set as the DNS server address. When the gateway (40) is an authentication-disabled terminal, the IP address of the DNS server (32) is set as the DNS server address. Thus, the DNS solution of the authenticated terminal (12) is performed by the dedicated DNS server (52).
摘要:
A telephone dialing system includes a memory unit for storing a dialed telephone number, a comparator for comparing first digit data of the dialed telephone number stored in the memory unit and second digit data of a telephone number presently being manually dialed and providing a first output when more than half of the digits of the first and second digit data coincide with each other while less than half of the digits of the first and second digit data do not coincide with each other so that the presently dialed number is an incorrectly dialed number and a second output when more than half of the digits of the first and second digit data do not coincide with each other so that the presently dialed number is a new number. An alarm unit issues an alarm in response to the first output. A speech output unit generates a speech output announcing the dialed telephone number stored in the memory unit. A confirmed dialed telephone number sending unit sends out the dialed telephone number announced by the speech output unit in response to a selection input generated by a user via manipulation of a specified special function key. A display unit provides a luminous or flickering display in response to the first output from the comparator unit. A comparative display distinguishably displays the coincidence part and the non-coincidence part of the first and second individual digit data.
