There is described a communication system allowing communication over one or more communication networks. The communication system includes a domain name server storing a zone data file for a domain associated with a first party, the zone data file including contact information associated with the first party, the contact information including a plurality of electronic communication identifiers associated with the first party with each electronic communication identifier being associated with a corresponding communication protocol. An access granting system enables the first party to grant a second party access to one or more of the plurality of electronic communication identifiers. In particular, the access granting system encrypts one or more electronic communication identifiers to generate encrypted contact information, stores the encrypted contact information in the zone data file in association with a sub-domain of the domain associated with the first party, and provides the second party with access to the identity of said sub-domain.
