Static IP Vs Dynamic IP: Difference Between Static and Dynamic IP

Want to know about Static IP vs Dynamic IP? Want to know the differences between Dynamic and Static IP. This article will give you a simple guide about Static, Dynamic IP, and Static IP Vs Dynamic IP.

What is IP address?

An IP address is a unique number given to your computer by your internet service provider called ISP.  It identifies your computer on the network.

Computers use IP addresses to locate and talk to each other on the Internet, much in the same way people use phone numbers to locate and talk to one another on the telephone. You will learn about static ip vs dynamic ip in this blog.

What is Static IP address?

A static IP address is a number in the form of dotted quad e.g. that is assigned to your computer by an Internet service provider (ISP) to be its permanent address on the Internet. Read more from Wikipedia.

What is Dynamic IP?

Dynamic IP address is a number in the form of dotted quad  that is assigned to your computer by an Internet service provider (ISP) which is not static in nature means every time you get connected to the network, you will be assigned a different IP address.

When you get connected with an Internet Service Provider you will either be provided a static IP address or a dynamic IP address, depending on the nature of service you require. Most IP addresses assigned today by Internet Service Providers to customers are dynamic IP addresses. It’s more cost-effective for the ISP and you. These dynamic IP Addresses are provided with the help of DHCP which resides within the routers.

It would be simple and good if every computer that connects to the Internet could have its own static IP number. The users of the internet have grown exponentially, so there are not enough static IP Addresses to go around. To get rid of that problem, many Internet service providers limit the number of static IP addresses they allocate and economize on the remaining number of IP addresses they have by temporarily assigning an IP address to a requesting Dynamic Host Configuration Protocol (DHCP) computer from a pool of IP addresses. You will be assigned a WAN IP Address from your ISP and further DHCP of your router/modem will assign you dynamic IPs to the computers which are connected to the router/modem.

Once the user disconnects from the Internet, their dynamic IP address goes back into the IP address pool so it can be assigned to another user. Even if the user reconnects immediately, they will not be assigned the same IP address from the pool. There are times, however, when users who connect to the Internet using dynamic IP wish to allow other computers to locate them. In that case, they would need a static IP address. They can ask their ISP to provide static IP Address which will probably involve an additional monthly fee.

When Should I use Static IP?

  • If you want to run your own website.
  • It’s good for dedicated services such as mail, FTP and VPN servers.
  • access a virtual private network from multiple PCs via a single broadband service
  • It’s good for creating or hosting computer servers.
  • Static IPs are used to see your CCTV cameras at home/business places/organizations, which you can see from any place with the help of the internet.

When Do I use Dynamic IP?

  • When several computers on an internal network with internet access on all of them, Dynamic IP addresses allow several devices to share limited address space which is available.
  • When a single computer which is connected to suppose your head office on a one-way Virtual Private Network
