Difference between Dynamic and Static IP

Key Difference: The major difference between dynamic and static IP is that dynamic IPs change every time one connects to the internet, while static IPs remain the same.

Internet Protocols, also known as IP addresses is a 32-bit number that is usually assigned to a computer when it connected to a network, such as the Internet. The IP address works similar to an actual address and lets computers know where to send data packets. The network devices use these address in order to communicate with each other.

The IP address are made up of 4 parts of numbers that are divided by dots (.) So, a typical IP address will looking something like – 72.169.189.01

Although, the computers communicate with each other using IP addresses, to make it easier to remember the internet uses DNS or Domain Name System. This DNS is sort of an address book that pairs names to IP addresses. For example, if one wanted to visit the Google website, they would type in www.google.com in the address bar. The DNS will look up the IP address (74.125.239.35) paired with this name and will ping that address. Their system will respond back and the webpage will load on your computer.

There are two types of IPs – dynamic and static IP addresses. The major difference between dynamic and static IP is that dynamic IPs change every time one connects to the internet, while static IPs remain the same.

There are limited amount of IP addresses that are available and for this reason, many companies assign dynamic IPs, unless a static IP is asked for. So, every time a device is connected to the Internet, the IP address can change. This also allows the limited number of IPs to become reused, making it more convenient.

Broadband connections today lease IP addresses and use the DCHP dynamic IP address system. This system is also often considered safer, since the IP is always changing it makes it more difficult to hack the computer. Static IPs are commonly used by companies or people who require a similar IP address. The can apply for a static IP by paying a fee.
