What Is Static IP Address?

A static IP address is an nothing but we can enter a manually IP address that was manually configured for a any device/computers/printers/routers versus one that was assigned via a DHCP server. It’s called static because it doesn’t change. It’s the exact opposite of a dynamic IP address,which does change.dynamic ip address is automatically changed of any time.this ip address is on lease.Static IP addresses are also sometimes referred to as fixed IP addresses or dedicated IP addresses.


Why Would You Use a Static IP Address?

Another way to think of a static IP address is to think of something like an email address, or a physical home address. These addresses don’t ever change — they’re static — and it makes contacting or finding someone very easy. Similarly, a static IP address is useful if you host a website from home, have a file server in your network, are using networked printers, are forwarding ports to a specific device, are running a print server, or if you use a remote access program. Because a static IP address never changes, other devices always know exactly how to contact a device that uses one.For example, say you set up a static IP address for one of the computers in your home network. Once the computer has a specific address tied to it, you can set up your router to always forward certain inbound requests directly to that computer, such as FTP requests if the computer shares files over FTP.Not using a static IP address (using a dynamic IP that does change) would become a hassle if you’re hosting a website, for example, because with every new IP address that the computer gets, you’d have to change the router settings to forward requests to that new address. Neglecting to do this would mean nobody could get to your website because your router has no idea which device in your network is the one that’s serving the website.Static IP addresses are also useful for when the device’s domain name is inaccessible. Computers that connect to a file server in a workplace’s network, for instance, could be set up to always connect to the server using the server’s static IP instead of its hostname.

Even if the DNS server is malfunctioning, the computers could still access the file server because they’d be communicating with it directly through the IP address With remote access applications like Windows Remote Desktop, using a static IP address means you can always access that computer with the same address. Using an IP address that changes will, again, require you to always know what it changes to so that you can use that new address for the remote connection.

Static vs. Dynamic IP Addresses

The opposite of a never-changing static IP address is an ever-changing dynamic IP address. A dynamic IP address is just a regular address like a static IP is, but it’s not permanently tied to any particular device. Instead, they’re used for a specific amount of time and then returned to an address pool so that other devices can use them.This is one reason that dynamic IP addresses are so useful. If an ISP were to use static IP addresses for all of their customers, that would mean that there’d constantly be a limited supply of addresses for new customers. Dynamic addresses provide a way for IP addresses to be reused when they’re not in use elsewhere, providing internet access for many more devices than what would otherwise be possible.
