Embodiment 1

[0023] Example 1, such as figure 1 As shown, this embodiment is a process based on the realteck chip platform, and the management IP of the routing device is 169.254.***.*** Terminal domain name access process, mainly considering that sometimes the upstream CHCP is not enabled for some reasons In the current situation, when the terminal performs anonymous access, it generally does not consider that DHCP may not be enabled, as shown in the figure: it mainly includes the following steps:

[0024] 1. The terminal computer starts to access the domain name.

[0025] 2. Check whether the uplink DHCP is enabled. If it is enabled, obtain the IP address corresponding to the domain name according to the normal access mode, and use the IP address corresponding to the domain name to access, and the domain name access process ends. Otherwise go to the next step to continue.

[0026] At present, to determine whether DHCP is enabled, you only need the PC to obtain the IP address to determi...

Abstract

The invention provides a router domain name access method suitable for being applied to a terminal with a windows operation system. When an upstream DHCP is not started, whether a local hosts file or netbios cache has the corresponding domain name or not is found, if not, a DNS packet is sent to query a network whether the domain name has the corresponding IP, and if not, an NBNS packet protocol package is sent. According to the method, a problem of accessing a router management interface in the condition that a router upstream DHCP is closed and a management IP is forgotten is solved.

Description

technical field [0001] The invention relates to computer network technology, in particular to a router domain name access method. Background technique [0002] Domain Name (Domain Name) is the name of a computer or computer group on the Internet consisting of a string of dot-separated names. , which defines the realm of executive autonomy, power or control over the Internet. A domain name is a "mask" on top of an IP address. The purpose of a domain name is to facilitate the memory and communication of a group of server addresses (website, email, FTP, etc.). Domain names serve as names for memorable Internet participants such as computers, networks and services. [0003] Router (Router) is a device connected to various LANs and WANs in the Internet. It will automatically select and set routes according to channel conditions, and send signals in the best path and in sequence. The router is the hub, the "traffic policeman" of the Internet. At present, routers have been wid...
