What is an IP address and How does it Work?
What is an IP Address?
An IP address is a unique identifier for a device (such as a computer, mobile phone, or router) on the internet. The IP address is made up of numbers and looks like this: 192.168.0.1
An IP number is an abbreviation of an Internet Protocol address and looks like this: 192.168.0.1. A MAC address is an abbreviation of a Media Access Control address and looks like this: 00-11-22-33-44-55
An IPS stands for Internet Protocols suite and it includes IPv4 and IPv6 Protocol.
How a Computer Obtains an IP Address
Computers typically get an IP address through a process called Dynamic Host Configuration Protocol (DHCP). The DHCP server assigns the IP address to the computer for a certain amount of time, known as a lease. When the lease expires, the DHCP server will assign another IP address to the computer.
A computer obtains an IP address by connecting to its local network and requesting an IP address from a DHCP server. Every device that connects to the internet is assigned an IP address. The IP address is a unique number that identifies a device on the internet and allows it to communicate with other devices.
An IP address is usually assigned by your ISP (Internet Service Provider) but in some cases, you can assign a static IP address to your device. The IP address consists of four numbers separated by dots, like this: 22.214.171.124
How to Find Your Computer’s Current IP Address
The IP address is a string of numbers that is used to identify your computer on the internet. It is often used to find out what country your computer is in.
One way to find your IP address is by going to a website that will show you what your IP address is. This can be done with the help of an IPS finder or an IPS locator. There are many websites that offer this service for free and some for a small fee. Users can easily find their IP Address by querying “What is My IP Address“.
What is the Purpose of an IPv4 Address?
An IP address is a number that is used to identify a device on the internet. It is a unique number that can be used to identify the device on the internet.
The address space for IPV4 is 232 or 4,294,967,296
The IP address has four sets of numbers separated by periods or dots known as octets. The numbers are represented as decimal values from 0-255. This means that there are 256 possible combinations of numbers for each set.
The following is an example of an IPV4 address in binary notation.
01110101 10010101 00011101 0000010
Internet addresses are usually written in decimal form with decimal points (dots) separating the bytes. the following is the dotted-decimal notation of the above address:
The IP address classes are in the following in decimal notations:
- 1-126: This range is reserved for Class A networks
- 128-191: This range is reserved for Class B networks
- 192-223: This range is reserved for Class C networks
- 224-239: This range is reserved for Class D networks
- 240-254: This range is reserved for Class E networks
- 0 [Zero] is reserved and it is used to represent all IP addresses.
- 127 is reserved and is used for testing, it is like a loopback interface.
- 255 is a reserved address and it is used for broadcasting purposes.
What is the Purpose of an IPv6 Address?
The purpose of an IPv6 address is to uniquely identify a device connected to the internet.
IPv6 addresses are 128-bit identifiers that are used to identify devices connected to the internet. They are a long string of numbers and letters that are usually written in hexadecimal. These identifiers come in two forms: unicast and multicast. Unicast is used for single-point-to-point communications, while multicast is used for one-to-many communications.
What is the difference between IPv4 and IPv6 Addresses?
The IPv4 address is a 32-bit address that has been used in the past. The IPv6 address is a 128-bit address that replaces the previous one. The main difference between these two addresses is the size of their IP addresses and the number of devices they can connect to, respectively.
- IPv4 addresses are limited to 4 billion devices
- IPv6 can connect up to 340 trillion trillion trillion devices
It’s also worth noting that, in a world with many more devices than available IPv4 addresses, the global registry of IPv6 addresses could be an important part of the Internet’s architecture.
What is the difference between IP address and MAC Address?
The IP address is the address that is used to identify and locate a computer or device on the internet. A MAC address is a unique identifier for network hardware. IP addresses are assigned by Internet service providers (ISPs) to devices connected to their networks. A MAC address, on the other hand, is assigned by the manufacturer of the networking device and it remains constant as long as that device is operational.
