Comprehensive Analysis of HiPER Broadband Router configuration DNS

Many people may not have a special understanding of the configuration of broadband routers. Here we mainly explain how to configure DNS for HiPER broadband routers. In recent years, with the increasing popularity of AI and HiPER series routers in the market, the hotlines of UTTCare call center 4006-781-781 are getting increasingly busy. From the technical feedback from many callers, it seems that many customers do not know much about the role of DNS in Broadband Router configuration, the following section describes the use of the public network DNS configured on the HiPER Broadband Router.
 
As we all know, when we are surfing the internet, such a website is actually a domain name, and computers on the Internet can only identify each other using IP addresses. You can also enter the 218.30.66.101 IP address, but we cannot remember or say this IP address is hard to remember, so we have the domain name statement, because such a domain name makes it easy for us to remember. My friends who want to use the HiPER vrohipof AI technology know that setting public network DNS on an intranet PC is used to resolve domain names on the Internet. So what is the purpose of the DNS configured on the HiPER broadband vrodns? Generally, a Broadband Router has a DNS proxy function. The so-called proxy means that it does not have a DNS resolution function, but it can help you complete the resolution task.

First, the bandwidth router configuration is a NAT principle. It can be divided into two IP addresses: LAN and WAN ports. LAN provides LAN gateway IP addresses and WAN ports provide Internet connections, after a Broadband Router is configured with an upper number, two DNS servers are obtained from China Telecom, China Netcom, and China tietong. This has nothing to do with the IP address set by the local machine, this DNS is basically a dns ip address that China Telecom, China Netcom, and China tietong think can be resolved normally. Next, let's talk about how DNS works when the PC configured with a Broadband Router sets the dns ip address to a lan ip Address: DNS request package ---> lan ip ---> the primary dns ip address obtained by the real dns ipwan port). When the PC is set to the local public dns ip address, the DNS works as follows: DNS request package ---> the primary dns ip address set on the real dns ippc ).

 
The difference can be seen from the above: when using a proxy, an extra step is required, and the DNS request packet is first sent to the broadband route, then, when the router sends the request packet to the destination dns ip address, the packet is sent to the destination dns ip address for resolution. It is because the proxy principle makes the domain name resolution not very stable during packet unpacking, which sometimes leads to resolution failures, therefore, we recommend that you configure public network DNS directly on the PC and Broadband Router for network stability and speed. We do not recommend using the DNS proxy function of the router.

In the client configuration, the server is ADSL access, and the applied dynamic domain name is server.iplink.com.cn. If no DNS is configured on the client, the VPN dialing link will cause a link exception because the dynamic domain name of the server cannot be resolved. For example, the session Status in the test link is always disabled. 3. IP addresses are allocated through DHCP in the Intranet. The TCP/IP attribute of each PC is set to automatically obtain the IP address. At this time, because the PC itself does not set its own public DNS, when it is automatically obtained, it must be divided into pre-configured public network DNS on the Broadband Router configuration. If no DNS is set on the HiPER at this time, the Intranet PC cannot open the webpage even if the IP address can be obtained.

Relationship between the preferred DNS server and the backup DNS server: if there is only one network connection such as one Nic), requests will be sent to the backup DNS server only when the preferred DNS server does not respond, if the preferred DNS server has a response, even an incorrect response will not be sent to the backup DNS server. Therefore, based on this principle, when we configure China Telecom Netcom dual-line on HiPER, even if the primary DNS is configured with China Telecom, the Standby DNS is configured with China Telecom. If the primary DNS is not faulty, it will always be in the response state, in the same way, even an error response will not be sent to the standby Netcom DNS server. Engineers remotely log on to HiPER to diagnose network connectivity and use the public network DNS configured on HiPER. If the public network DNS is not correctly configured on HiPER, this will affect the speed and accuracy of Remote Assistance from ai tai engineers in diagnosing network faults.

Conclusion

To sum up, I think everyone has learned the importance of setting the correct public network DNS on HiPER, we hope that the shared DNS knowledge will help you better use HiPER to solve your network problems.
