Types of IP addresses

well, there are different categories of IP addresses, and within each category, different types.

Public IP address

A public IP address is a unique IP address for the identification of a particular network. every public IP address is provided to the router of a network by ISP (Internet Service Provider).

An ISP (internet service provider) is a company that provides individuals and organizations access to the internet and other related services.

Public IP addresses are either static or dynamic in nature.

  • Dynamic IP address
  • Static IP address
Private IP address

Private IP addresses are unique addresses that belong to internet-connected devices like smartphones, computers, and tablets,... The router in a network generates a unique private IP address for every device that is connected to a network.

Consumer IP address

Consumer IP addresses are the IP addresses of individuals who use the internet. These could be either public or private in nature. While a private IP address can be used within a network, outside a network, public IP addresses are used.

IP version 4 addresses are 32-bit integers that can be expressed in hexadecimal notation. The more common format, known as dotted quad or dotted decimal, is X.X.X.X, where each X can be any value between 0 and 255.
