Embodiment Construction

[0063] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.

[0064] The present invention proposes a method and equipment for realizing binding update of dynamic domain name and IP address by ACS agent family or enterprise gateway.

[0065] It mainly includes the following technical solutions:

[0066] The domain name storage table is preserved in the gateway management system, and the domain name storage table includes the domain name of the gateway device and the port number of the gateway device wide area network (WAN) port, the binding information of the gateway device identity ID; the gateway management system learns the gateway device domain name or When the IP address changes, the local domain name storage table is changed according to the current change; the gateway management system sends the current change information to the DNS server of the domai...

Abstract

The invention discloses a method and equipment for realizing the updating of a dynamic domain name. The method comprises: a domain name storage table is saved in a gateway management system, wherein the domain name storage table comprises a domain name of gateway equipment and binding information of an IP address; the gateway management system finds that the domain name of the gateway equipment or the IP address is changed, the local domain name storage table is changed according to current changed situation; and the gateway management system sends the information of current changed situation to a DNS server of a domain name service system. The method only needs to add certain functional modules to an ACS server, does not need to reconstruct or upgrade relevant systems and can provide DDNS service for a gateway owner without needing the gateway to add any function to the DDNS service.

Description

technical field [0001] The invention relates to the dynamic domain name service technology on the Internet (Internet), in particular to a method and equipment for realizing the update of the dynamic domain name. Background technique [0002] Each domain name on the Internet corresponds to a public IP address, and these public Internet Protocol (IP) addresses are usually fixed. For home or enterprise gateways (such as dial-up or DHCP) that dynamically obtain IP addresses to access the Internet, the public IP address is dynamically and temporarily assigned by the operator, so the domain name cannot be statically bound to the IP address. Dynamic Domain Name Service System (DDNS, Dynamic DNS) can resolve the binding relationship between dynamic IP and domain name. No matter how the public IP address changes, applications on the Internet can access the external services provided by the gateway through this fixed domain name. [0003] The terminal management system ACS (Automati...
