Abstract
A system establishes virtual DNS servers that are supported by a DNS server. Target IP addresses are assigned for the virtual DNS servers. Network capable devices are uniquely assigned to the virtual DNS servers for domain name resolution. Each network capable device accesses the communication network through a corresponding network device associated with a corresponding source IP address. A client's service plan is assigned to a first network capable device used by the client. The service plan is implemented through a DNS request under a session established between the first network capable device and its assigned first virtual DNS server. The session is uniquely identified by a first source IP address of a first network device used by the first network capable device to access the communication network and a first target IP address of the first virtual DNS server.
