[Solution] An ENUM/DNS system 100 configured to include an ENUM/DNS client 20 which makes a connection destination information inquiry indicating a connection destination corresponding to the telephone number of a terminating terminal, the telephone number being appended to a connection request sent by an originating terminal; and an ENUM/DNS server 10 which accepts the connection destination information inquiry and outputs the connection destination as a connection destination inquiry response, wherein the ENUM/DNS server 10 is provided with a determination unit which, on the basis of the connection destination information inquiry, determines the attribute of the originating terminal, and a conversion unit which, on the basis of the attribute, converts an SIP domain included in REGEXP of the connection destination information inquiry response into an SIP domain indicating the connection destination.
