An IP address (Internet Protocol address) is a unique identifier that is assigned to every device that connects to the internet. It is a 32-bit (IPv4) or 128-bit (IPv6) number that is used to route data packets to the correct device. IP addresses are important for a number of reasons. They allow devices to communicate with each other on the internet. They also allow websites to track users and serve them personalised content. And they can be used to block access to certain websites or services.
Types of IP Address
There are many types of IP addresses, below are the most common IP types.
IPv4 is the older version of IP addresses. It uses 32-bit addresses, which means that there are a total of 4.3 billion possible addresses. IPv4 addresses are divided into two categories: public and private. Public IP addresses are assigned to devices that connect to the internet directly. Private IP addresses are assigned to devices that are connected to a private network, such as a home or office network.
IPv6 is the newer version of IP addresses. It uses 128-bit addresses, which means that there are a total of 340 undecillion possible addresses. IPv6 addresses are designed to address the growing number of devices that are connecting to the internet. IPv6 addresses are also more secure than IPv4 addresses.
Dynamic IP Address
Dynamic IP addresses are assigned to devices by a DHCP (Dynamic Host Configuration Protocol) server. When a device connects to the internet, it requests a DHCP lease from the DHCP server. The DHCP server will then assign the device a dynamic address for a certain period of time. Once the lease expires, the DHCP server will assign the device a new IP address.
Static IP Address
Static IP addresses are assigned to devices by a network administrator. They do not expire and they are always the same. This is useful for devices that need to be accessible from the internet, such as web servers and email servers.
