When manually changing the IP address, you cannot simply enter any numbers. IP addresses must follow certain rules and should be within a range valid for your network. Here are some important points that you should note:

  1. Valid address area: Your network, whether at home or in the office, will use a specific area of IP addresses specified by the router or network administrator. The address you choose must be within this range.
  2. Subnet mask: The subnet mask of your network determines which part of the IP address identifies the network and which part identifies the specific hosts (e.g. computers, printers). Your chosen IP address must be compatible with this mask.
  3. Avoid conflicts: Make sure that the IP address you choose is not already used by another device in the network. This can lead to conflicts in which one or both devices cannot establish a network connection.
  4. Fixed or dynamic assignment: If your network uses DHCP (Dynamic Host Configuration Protocol) to automatically assign IP addresses to devices, you should not manually set an address within the DHCP range, unless you reserve it explicitly in the router.

If you want to change your IP address manually, you should call the network settings of your operating system and make the corresponding settings there. In Windows, this happens via the “network and release center”, in macOS via the “system settings” and then “network”. You should also consider consulting a network administrator to ensure that your changes do not cause problems in the network.

If you don’t know what you do, leave it on automatically.

This is the local IP address assignment, either you can assign a fixed IP to your device in the home network (in the same network segment, you understand) or leave it to the DHCP server to automatically assign the address to the device, by the way, the latter takes over your Fritz!BOX or the device that provides you with your internet provider.

This IP only applies to the home network, has nothing to do with the IP that you see from “draussen” (=Internet). And of course you cannot enter any address there.

What do you want to achieve with a manual input? “Automatically” means that your router automatically gives you a home network IP.

What a new IP address? This is the address where your device can be accessed in the local network – no longer. IPv4 is not routed to the outside. Outside your local network, the IP does not know anyone.

Nevertheless, if you want to manually assign the IP, it must come from the network area of your router and be an address that the router does NOT have in its DHCP address pool.
Example for a Fritzbox with default settings: The router uses the 192.168.178.001 with subnet mask 255.255.255.0.
The router’s DHCP server is distributed, for example, from 192.168.178.10 to 192.168.178.200.(here in the router, check which addresses are precisely defined!)
You can then use any address between 192.168.178.002 to 192.168.178.009 and 192.168.178.201 to 192.168.178.254, so that there are no collisions.
And as you see, all addresses begin with 192.168.178. This is the network component of the IP. Only the last three digits (usable from 1 to 254) differ from device to device and identify the terminal within the own network.

As stated, your computer IP has nothing to do with the IP visible on the Internet, which the provider gives, since you have no influence. If you can restart the router, you will usually receive a new IP. But has nothing to do with your entry in the computer.

The “dumme employee” has access to the router settings?, How, where else it should have made a restriction.

No, the number must follow a certain pattern. There are different, it depends on your used network. In addition, you will pass the DHCP, which is somehow stupid. If you want to change it, I’d change it firmly in the router. In this case, the setting remained automatically at the client. This also prevents you from getting your address because it has already been assigned to another device.

In addition, the address is only valid in the network behind the router. A different address is used on the Internet.

No, leave on automatic.
