Shock IP Changer is a useful and convenient free tool that works as a small database for all your IP addresses. You can store as many network configurations as needed, and select any of them with just one click instead of changing all of your connection parameters every time you need to connect to a new network.
This may come in very handy if you happen to be frequently on the move, and that is why this tool has been specifically designed for those of you who travel with your portable computer. Actually, Shock IP Changer comes in two flavors – a PC version and a portable version that you can execute from your pen drive or any other external device.
The program allows you to add new entries regardless of the type of host you are trying to connect – thus, you can create new IP entries both for DHCP connections and for those with a static IP address. In this case, you will need to specify the IP address, the Subnet Mask, and the Gateway, as well as the two corresponding DNS. You can also associate a specific printer to each new IP, so that all you will need to do is to select the right entry from your Shock IP Changer database and start browsing right away.
