DNS conflict in the home network - you can do that

If you use multiple devices in your network, DNS conflicts can occur. We'll show you how to fix them.

DNS conflict in the home network - this can be the reason

A DNS conflict exists when multiple devices on your network try to assign an address to other devices.

• The DNS server in your home network assigns the IP address and thus establishes your connection to the Internet.
• The most common cause of DNS conflicts are multiple routers in the network, for example because you want to increase the range of your WLAN connection. Both routers offer themselves as DNS servers, although one of the routers, which is only in the other router, does not have its own network connection.
• However, Windows computers can also be set to act as a DNS server.
• You can easily remedy problems of this kind by manually setting each device, i.e. setting the DNS server and IP address yourself.

Define network settings in the home network yourself

To avoid DNS conflicts, you can set each device manually.

1. First, you need to find out which is the right DNS server on your network. It is best to cut off all devices from the network and only connect to a simple device such as a smartphone.
2. When the connection is established, you have to read 3 things: standard gateway, DNS server and the IP address.
3. You can now manually set the settings on any other device. The standard gateway and DNS server are always the same, the IP addresses must always be different. For the latter, only change the last digit and keep a distance between the numbers so that there is not the same address twice.
4. You can find out in detail how to change your IP address in this practical tip.
5. If there is still a problem, you can change the DNS suffix. We will also explain in detail how you make this setting in another practical tip.
