Abstract
A message is received which indicates a request for a client-specific service address for service or content provided by a service provider. In response to the request, a client-specific service address may be generated and sent to the client. The address may be used as a destination address in one or more subsequent client requests for service or content. A first portion of the address comprises an IPv6 service prefix assigned to a service network of the service provider. A second portion of the address comprises semantic information having a first portion of encrypted private information and a second portion of unencrypted service information. The encrypted private information may be generated by encrypting private information based on a cryptographic key, where the cryptographic key is derived based on a secret key associated with the service provider and an IP client prefix assigned to the client.
