Whether you use static or dynamic IP addresses, your router relies on information it stores in your personal computer’s hard drive to keep the IP scheme of the network. The router responds to the decline of the old hard drive’s information by putting the computer a fresh IP address when you alter a computer’s hard drive.

Hard Drive Shift
The hard disk is where nearly all of the information of your computer’s lives. Your RAM just save temporary information, as well as the firmware of your motherboard lives on a ROM chip. Settings information you place through your operating system is, however, relied on by the network adapter. Your computer stores this information in your hard disk, and this information is lost by your personal computer when you alter your hard drive.

Dynamic IPs
It uses the Dynamic Host Configuration Protocol when you let your network gear mechanically create IP addresses for your pc. Your new hard drive is going to have distinct DHCP client, which the DHCP server in your router is not going to recognize.

Static IPs
Using static IP addresses ensures your computer will consistently possess the exact same IP address of your choosing in your network. This needs a few setup steps on both your operating system and from inside the control panel of your router. As shifting hard drives means a DHCP server will recognize your personal computer as an identical machine, when you’ve got a static IP address, altering hard drives means your pc will lose the information for the static IP address you configured.
