What is IP?

Devices on local networks are identified by IP addresses, which are unique. The Internet Protocol (IP) represents a collection of rules that regulate the format of data transferred over a local network or the internet.

IP addresses are simply the main identifiers that authorize data exchanged between different devices on networks: they comprise information and allow communication between different devices. The internet needs a good method of differentiating between various routers, webpages, and computers. IP addresses represent a major aspect of how the internet works and grants a means of doing so.

The main string of digits separated effectively by periods constitute an IP address. IP addresses comprise four integers, for instance, The set’s numbers vary from 0 to 255. Due to this fact, the entire IP addressing range is to 255.xxx.xxx.xxx.xxx. IP addresses are simply not generated at random. The IANA – Internet Assigned Numbers Authority, a significant part of the Internet Corporation strictly for Assigned Numbers and Names, assigns and creates them mathematically. ICANN represents a non-profit organization founded in the US in 1998 to help keep the internet accessible and secure to everyone. Every time an individual registers a domain name on a network, they do so via a registrar for the domain name, who pays ICANN nominal fees.

What Does an Internet Protocol Address Entail?

Computers utilize IP addresses to receive and send data over the internet. Most IP numbers are numerical; however, certain addresses have different letters as internet traffic grows. IP addresses are mainly divided into four categories: private, static, dynamic, and public. While private and public imply network location (private being used within a network and public being utilized outside of a network), dynamic and static represent network permanency.

A static IP address represents one created manually instead of being assigned. A static IP address is permanent, but a dynamic IP address is assigned by a Dynamic Host Configuration Protocol (DHCP) server and can change. The most prevalent type of internet protocol address is dynamic IP address. Dynamic IP addresses are only valid for a certain period before they expire. Either the computer will automatically request a new lease or be assigned a new IP address.

Because each IP address is fully unique to the machine or person to whom it is allocated, it can be compared to a Social Security Number (SSN). Routers can use these numbers to figure out where they’re transferring information over the internet. They also ensure that the messages are delivered to the relevant devices. Like a post office, a router requires an IP address to deliver a package to the desired website.

IP addresses aren’t mobile…….

Furthermore, your IP address (Home) does not accompany you if you go on vacation with your laptop. Since you’ll be connecting to the Internet over different networks while on vacation, it can’t.

When you use a coffee shop’s WiFi to check your email in another city or state (or simply down the road), you’re utilizing a separate IP address, one assigned to your laptop on the fly via the ISP for that shop’s Internet provider. When you travel, the same thing happens. Your IP address varies every time you go from the airport to your accommodation to the neighborhood coffee shop. You don’t have to think about it or open up your computer’s hood and flip switches. All of this is possible because of the clever design of the Internet, wireless networks, and the Internet Protocols that your computer uses.

Studying the Allocation of IP Addresses

IP addresses are assigned in two ways: static and dynamic. Your network, ISP, and device features influence how your device is issued an IP address.

If the IP address is dynamic, it is created automatically; if it is static, it is created manually. A static address is fixed or permanent, but a dynamic address changes with each internet connection. Every time you restart your computer, you can get a dynamic IP address. Your network connection determines who or what assigns IP addresses. The IANA manages worldwide IP numbers, subsequently maintained locally by your ISP, company administrator, or home router.

What Are the Different Kinds of IP Addresses Available?

IP addresses are divided into groups, with distinct types within each category.

  • IP addresses Designed for consumers

Every person or company with an internet service plan will have two IP addresses: Public IP addresses and Private IP addresses. The phrases public and private reference to a network location; a private IP address is utilized within a network, while a public IP address is utilized outside of one.

  • Private IP addresses

A private IP address is singly assigned to each device that connects directly to your internet network. Smartphones, tablets, and computers are included in any devices enabled by Bluetooth, such as printers, smart TVs, and speakers. The number of IP addresses at home is most likely to increase as the internet of things alleviates. Your router will require a mechanism to distinguish between these items, and most of them will need to recognize each other. Due to this fact, your router generates private kinds of IP addresses for every device, which serve as identifiers on the network.

  • IP addresses that are available to the general public

The primary address for your entire network is a public kind of IP address. While every connected device has its IP address, they are all a part of your network’s IP address. AS DISCUSSED ABOVE, your ISP grants your router the public IP address. ISPs typically have a pool of IP addresses, and it is from this, they assign addresses to their prospective clients. Your public IP address is the address that all devices connected to the internet users to identify the network.

Public IP addresses are mainly of two types

  • Dynamic IPs 
  • Static IPs

Dynamic IPs

These kinds of IP addresses change regularly. ISPs purchase a pool of IP addresses and automatically assign them to their clients. They also actively re-assign them regularly and return the older IP addresses to the big pool for usage by other types of clients. The rationale behind the strategy is to save money for the ISP effectively. ISP doesn’t have to carry out specific procedures to re-construct a customer’s IP address if they get to move house, for instance, because the routine transfer of IP addresses is simply automated. There are security advantages, as a moving IP address makes it harder for hackers to gain full access to network interfaces.

Static IPs

Unlike dynamic IP addresses, Static IP addresses do not change. The IP address assigned only by the network does not change. This type of IP address is not needed for most businesses and individuals but for businesses that plan to host servers. This is simply because a static IP address makes sure that the email addresses and websites associated with it possess a stable IP address, which is critical if you desire other devices to be capable of finding them regularly on the internet.

Comparing IPv6 and IPv4 Protocols

IPv4 is the original Internet Protocol. As we’ve seen, an IP address is defined as a 32-bit number, such as 506.457.14.512. That only leaves about 4 billion IP addresses available, insufficient for continuing use.

IPv6 is a brand-new protocol that debuted in 1998. The deployment began in the mid-2000s and is still ongoing. You may find out if you’ve been allocated an IPv6 address by going to WhatIsMyIP.com. The new protocol uses 128-bit IP addresses with the following format: 4ggr: 1925:5656:7:600:t4tt:tc54:98vt.


This means that IPv6 can give around 340 trillion IP addresses. For years to come, that will be more than enough to meet the rising need for IP addresses for websites, laptops, cellphones, smartwatches, and smart refrigerators.

The Relationship Between Domain Names and IP Addresses

Names are more familiar to humans than numbers. A domain name like wpbeginner.com is easier to remember than a long list of digits like The Domain Name System (DNS) on the internet is similar to a phone book. When an individual types a domain name like wpbeginner.com, it looks up the phone number and IP address and connects you to the website.

What’s intriguing is that your WordPress site only knows the URL and not the IP address. This makes switching to a new hosting provider, where your website’s URL will likely change, much easier.


Nothing on the internet can function without Internet Protocols. Internet Protocols and their versions must be updated regularly to communicate effectively over the internet. The entire data transport is handled by the IP addressing system and transmission control systems. TCP/IP is required for both complicated and simple networks to function on the internet.
