In Windows 7, change the MAC address:

  1. Log in to the Device Manager.
  2. Find the Network adapters drop-down list.
  3. Find your network card and click on it with the left button, then select "Properties" (Properties).
  4. Advanced tab (Advanced).
  5. On the right is the "Properties" (Value).
  6. Fill in the new MAC address without colons and spaces.
  7. Reboot.

Change MAC in Ubuntu :

sudo gedit /etc/network/interfaces //Увидите эти строчки, но могут быть варианты. auto eth0 iface eth0 inet dhcp //На эти auto eth0 iface eth0 inet dhcp hwaddress ether 01:02:03:04:05:06 sudo /etc/init.d/networking restart

In other Linux, this is no more difficult.

There are also programs not to go anywhere, but I don’t think that it’s difficult for you to type in the google “ program for changing the MAC address ”. But I want to warn you, because, having changed the MAC, you didn’t protect yourself, except that you can bypass a MAC lock, for example, in Wi-fi networks.

The principle of operation of the router is quite simple:

  1. The DCHP server on the router gives your device an IP address, you can change it only in the settings of the router, your IP for the router does not make sense to change, usually it is 127.0.0.1.
  2. To communicate with the Internet, a router via a "modem" or "cable" also requests an IP address from an Internet provider. Therefore, it cannot be changed either, unless you are a provider.
  3. Your devices have access to the Internet with the IP given to you.

Based on the foregoing, if you are not a provider or non-FSB , then it is impossible to find out the identity of the advertiser.

"Do you want to be not found on the network? - Do not use the network."

    The provider of you has all the information that will help identify you. Having changed the ip address and mac, there is no way to hide, because there is still the port number of the router from which the cable goes to the apartment. Also, changing the mac and ip, you can be blocked on the routers of the provider, firewall or other means.
