What does the dhcp service not responding mean?

The dhcp service does not respond because there is an error in automatically obtaining the IP address service. Reconfigure the service. Reasons for no response: 1. The "Automatically obtain IP address" function is not turned on, and you only need to set the IP to "DHCP"; 2. Caused by network fluctuations, the device is connected to the network, the router assigns an IP address, and the device obtains an IP address. This requires a process. If the network fluctuates during this process, the device will be unable to obtain an IP address. 3. Equipment problems. If the router's cache is full and crashes, IP addresses cannot be assigned to networked devices.

DHCP was developed and designed by the IETF and became a standard protocol in October 1993. Its predecessor was the BOOTP protocol. The current DHCP definition can be found in RFC 2131, and the proposed standard based on IPv6 can be found in RFC 3315. The function of the dhcp server is to "dynamically allocate management IP addresses".

The dhcp service does not respond because there is an error in automatically obtaining the IP address service. Reconfigure the service.

Causes and solutions for dhcp service not responding

1. The "Automatically Obtain IP Address" function is not turned on

Maybe many friends are not particularly familiar with the DHCP function. Taking the home network as an example, if the user turns on the DHCP function in the router, then the device connected to the router As long as the DHCP service is turned on at the same time (also called "obtaining an IP address automatically"), the router will automatically assign an IP address to the connected mobile phone, and the mobile phone will also automatically obtain the IP address assigned by the router. When the "DHCP service is not responding" message appears Sometimes, it may be caused by the mobile phone not setting "obtain IP address automatically". In this case, just set the IP to "DHCP".

2. Network fluctuations

In addition to the first situation, there is another situation caused by network fluctuations. The device is connected to the network, the router assigns an IP address, and the device obtains the IP address. This requires a process. If the network fluctuates during this process, the device will be unable to obtain an IP address and a "DHCP service is not responding" situation will occur. This kind of situation is not a big problem. Just choose "Disconnect" or "Forget Network" and then reconnect.

It is normal for such prompts to appear. It does not mean that there is a problem with the mobile phone or router. It is just caused by an unknown error encountered during the connection. After directly disconnecting or forgetting the network, Reconnect to recover.

3. Equipment problem

If the IP of the mobile phone is set to DHCP and the problem still exists after reconnecting to the network, it is most likely that there is a problem with the router. It is normal. , the router will automatically assign IP addresses to connected devices. However, if the router's cache is full or crashes, it will not be able to assign IP addresses to connected devices. In this case, you can restart the router and the connection will be normal.

Many users may say that when the router is turned over, there is no button to control the restart. If there is no switch behind the router, you can directly unplug the power plug and wait for 15 to 30 seconds. , and then plug it in, which is equivalent to restarting.

Conclusion: Most problems are caused by the device itself, but it is not ruled out that it is caused by hard damage to the device. However, such problems cannot be solved by ordinary users, and many problems must be combined with the nature of the network the user is connected to. , usage environment, and equipment judgment, it is best to find professionals offline to help diagnose.
