ABSTRACT:
A home gateway apparatus is connected to a DNS server that stores and manages telephone numbers and an external NAPTR record corresponding to each telephone number. The home gateway apparatus also includes and mutually connects a plurality of internal terminals. The home gateway apparatus includes an NAPTR record generator that generates an internal NAPTR record of all internal terminals; an internal NAPTR memory area that stores the generated internal NAPTR record; an external NAPTR memory area that stores an external NAPTR record, which is selected from the internal NAPTR record to be allowed to be disclosed to the DNS server; and a self NAPTR record notification unit that notifies the DNS server of the external NAPTR record so that the DNS server can register the external NAPTR record in association with a telephone number.
