IP Addresses – Basics

What is the difference between a dynamic and static IP address?

When a device is assigned a static IP address, the address does not change.

Most devices use dynamic IP addresses, which are assigned by the network using Dynnamic Host Configuration Protocol (DHCP) when they connect and theychange over time, or when a connection is reset.

What is a Public IP Address?

A public IP address is an address provided that is provided by your internet service provider (ISP) to your network. On the internet, it recognizes your device.

The internet is accessed through your router’s public IP address. Public IP addresses are commonly used by publicly accessible enterprises such as websites, DNS, and VPN servers because they can be accessed from anywhere in the world.

You can not go online without having your public IP address, which identifies your device on the internet. Your router is an intermediate between your computer and the internet on a typical home network.

What is a Private IP Address?

A private IP address, also known as the local IP address, is the IP address your network router allocates to your device.

This address is only visible within your network, so it is unavailable on the internet. Each device on the same network is assigned a unique private IP address that allows them to communicate with other devices.

The device in your home can have the same private IP address as your neighbors’ device or anyone else’s all over the world, with private IP addresses.

This is due to the non-routable nature of private addresses.
