An embodiment of the invention comprises a method and apparatus for providing dynamic name resolution services based on information stored and served in a root server. A multi-part reference to the name resolution server is stored on the root servers. By analyzing the reference to the name resolution server, the name resolution server is capable of dynamically generating a canonical name associated with a domain and/or a host name. The domain and/or host name may be further examined by network resource servers to determine further information about a requested resource.

Resolving information associated with a network device includes receiving a request for first information associated with the network device. The request includes second information associated with the device, such as identification information. Based on the second information, an entry that includes the first information in association with the second information is located in a security association database. For example, an entry that includes the information association is located in a Security Association Database (SAD) of an IPsec endpoint device. The first information is read from the entry and a response to the request is based on this first information. The association between the first and the second information that is stored in the relevant database may be based on an identification authentication mechanism. Thus, for example, a management station is able to obtain the dynamically assigned network address of an interesting IPsec endpoint device by providing identity information associated with the device.

The invention discloses a method, system and client-side for achieving flow optimization based on a domain name resolution request. The method comprises the steps that the domain name resolution request is obtained and redirected to a local domain name resolution service process which is provided by local VPN service; in the local domain name resolution service process, whether a domain name corresponding to the domain name resolution request is matched with a domain name recorded in a local domain name blacklist is queried; if it is queried that the domain name corresponding to the domain name resolution request is matched with the domain name recorded in the local domain name blacklist, flow generated by the domain name resolution request is prevented. By the adoption of the scheme, when the client-side initiates the domain name resolution request used for obtaining advertisement content, the domain name resolution request will be prevented because the domain name corresponding to the domain name resolution request is matched with the domain name in the local domain name blacklist, namely the flow generated by the domain name resolution request is prevented, and therefore the influence of mobile phone advertisements on a user is effectively restrained.
