IPv4 Address Auto configuration Solution

Sometimes if we use a LAN network at the office there is an IP conflict or for no apparent reason our IP has been set static but after viewing it turns out that the IP we set is different from the one that runs so that even though we have set the IP accordingly it will not be able to connect to the internet.

On this occasion, the admin will provide ways to overcome IP address conflict or Autoconfiguration of different IPv4 addresses when in Settings. indeed, this problem is rather difficult to explain but for those of you who feel that you have managed a static ip and the internet still does not work, you can follow the method that we will discuss below.

Indication Of The Problem

PC can not connect to the internet (cable) when the settings are appropriate we set. When we look at the details of the ip address there is something strange that appears the description "Autoconfiguration IPV4 address: xxx.xxx.xxx.

Sometimes there are also those who experience when they are connected to the internet suddenly a notification appears "Ip Addres Conflict".

or if you don't know, you can figure out the problem with the ipconfig /all command. To do this, click start > Run | or press the CTRL+R keys and type CMD press enter. a CMD window will appear then type ipconfig / all and then press enter.

If you see the results of IPv4 Autoconfiguration different from the ip address that we set, then that's the cause.

First solution-CMD

The first way to solve the IP address autoconfiguration problem is to use the CMD / Command Prompt command. Press the CTRL + R keys and then type CMD and press enter. Command input

netsh interface ipv4 show inter

the result will come out as follows :

Idx Met MTU

--- ---------- ---------- ------------ ---------------------------

1 50 4294967295 connected Loopback Pseudo-Interface 1

11 10 1500 connected Local Area Connection

Well, this number 11 may be different on each PC, but the number in this section is what you should remember because later we will use this number.

Next, type this command in CMD:

netsh interface ipv4 set interface 11 dadtransmits=0 store=persistent

If so, the last step we need to do is disable the DHCP client. Press CTRL + R and type Services.msc and press enter.

double click on DHCP Client and then on Startup type select Disable. You can restart your PC and see the results.

Second solution - Uninstall drivers

If the first method does not succeed in overcoming the problem of the emergence of autoconfiguration ipv4 address, then the thing we can do is to reset all the networking settings that we have. The easiest way is to remove the Ethernet/LAN driver, but this method requires an internet connection later, so you can prepare a usb modem in advance. The way is:

Go to control panel > search for Device Manager. find the ethernet / LAN driver.
