Before we proceed further, let’s have an insight for public IP address. Your Internet Service Provider allocates the IP addresses for connecting your device to the Internet. Therefore, it can be very hard to change your IP address, particularly if you want to change them quickly.

When the Internet service provider assigns static IP addresses, you will have to request your Internet service provider and collaborate with the technical staff for getting a new address if you want to change your current IP address.

However, normally most of the Internet service providers allocate dynamic IP addresses using DHCP service. The terms of service by Internet service providers dictate how to change IP address in such cases. You can use ipconfig or other utility to release and renew your dynamic IP address when your computer is directly connected to the Internet. If you experience any technical problem, you can consult with your Internet service provider (ISP). In some cases, your Internet service provider might require you to disconnect your modem for few hours or days before they can assign you a new dynamic address.

However, the private IP addresses that are internally used on your local network can be easily changed. In case of static IP addresses, you can simply enter new static IP address on your device. In case of dynamic IP addresses assigned through your network router, you have the following options:

  • You can release current IP address and renew DHCP address on the clients.
  • You can assign a different IP address range of your router or other DCHP server and update addresses of other devices on the network according to the new range.
  • You can simply change the dynamic address to static address for the devices on the network. You can allocate a mix of dynamic and static address for clients on the same network as long as you don’t assign the address range reserved for the DHCP server.

Why Change Your IP Address?

Now the question arises as to why change your IP address. You can change your IP address to visit and use the websites that place the user restrictions based on IP address. You can easily pass through the user restriction based on region and nationality; however, changing your IP address can have no effect when the sites block you based on other criteria such as user names.

Changing IP address can also solve some technical issues that arise when your ISP assigns invalid addresses due to any hardware or software problems. This can be absolutely sound requirement for changing Public IP address. The changing of the private IP address has nothing to do with internet access, but it can be beneficial to change your private IP address in the following scenarios:

  • When you have incorrectly configured your private IP address using an invalid numeric range.
  • When your router is malfunctioning and allocating the same private IP address used by the other clients on the network.
  • When you are configuring the new router to use the default IP address range on your home network.
  • When assigned IP address by you doesn’t influence the security and performance of your network.
