  • The difference between Static IP and Dynamic IP:
    Static IP :
    A static IP address is an address that is permanently assigned to you by your ISP , and does not change even if your computer reboots. Since static IP address is assigned to you, you’ll have to manually configure your machine (router or server) to use the static IP address assigned to you.

    Static IP address Advantages:-
    >Address does not change – good for web servers, email servers and other Internet servers.
    >Use DNS to map domain name to IP address, and use domain name to address the static IP address. Similar can be achieved with Dynamic DNS for dynamic IP address, but it’s not as clean as the static IP address.

    Static IP address Disadvantages:-
    >Expensive than dynamic IP address – ISPs generally charge additional fee for static IP addresses.
    >Need additional security – Since same IP is assigned to a machine, hackers try brute force attack on the machine over period of time.

    Dynamic IP:
    A dynamic IP address dynamically assigned to your computer by your ISP. Each time your computer (or router) is rebooted, your ISP dynamically assigns an IP address to your networking device using DHCP protocol. To find your dynamic IP address, you may visit What is my IP address page.

    Dynamic IP address Advantages:-
    >Cheaper than static IP address.
    >Changing IP address gives more privacy.

    Dynamic IP address Disadvantages :-
    >Requires DHCP server to obtain an IP address.
    >Non-static. Each time IP address changes, you may have to find you IP address again.
