The word “IP address” is often heard in the large world of the internet, yet few people know of its importance. Although it may sound like technical jargon, an IP address is just as important to your online experience as a phone number is to making phone calls. We’ll discuss what an IP address is, why you need one, and how important it is to every day’s online activity in this blog.
What is an IP address
IP address stands for “Internet Protocol address.” A collection of rules for online communication, including emailing, streaming video, and connecting to websites, is known as the Internet Protocol. A network or device on the internet is identified by its IP address.
The process of allocating a unique IP address to every unique device is managed by the internet protocols. (Internet protocols perform additional functions, like traffic routing.) It’s simple to identify which devices with internet access are sending, requesting, and receiving what data in this manner.
Similar to phone numbers, IP addresses have the same function. Your phone number lets others know who you are and reassures the person answering the phone that you are who you say you are when you get in touch. All devices connected to the internet have an IP address because IP addresses perform the same function when you’re online.
IPv4 and IPv6 are the two different formats for IP addresses. If you count the numbers, it’s simple to identify the difference. IPv4 addresses are made up of four digits, from 0 (the first one excluded) to 255, with a period between each one. An example of an IPv4 address would be 5.62.42.77.
The parts of an IP address
The network ID, which consists of the first three numbers in the address, and the host ID, which is the fourth number in the address, make up an IP address. Therefore, the network ID on your home network, which is 192.168.1.1, for example, is 192.168.1, and the host ID is the last digit.
The device’s network is indicated by its Network ID. The particular device on that network is identified by its Host ID. (Typically, your router is set to.1, and after that, a device is assigned for each one.2,.3, and so forth.)
It’s possible that you won’t always want to share your exact device and network setup with strangers. In this situation, a Virtual Private Network (VPN) can be used to hide your IP address from the public. Using a VPN stops your address from being seen on your network.
Where do IP addresses come from?
When the internet first went live, IPv4 was a private network used by the military in the early 1980s. It may seem like a lot, but IPv4 has a pool of 4.3 billion addresses overall. However, we have run out of IPv4 addresses due to the vast amount of computers, smartphones, tablets, and Internet of Things devices that are connected to the internet. In reality, in the 1990s, we started to run out. Things have continued thanks to very smart technical networking methods.
About ten years ago, the Internet Engineering Task Force (IETF), that develops the internet’s core technology, developed IPv6. We can (in principle) never run out of addresses because it contains a theoretical pool of 340 undecillion addresses, which is the number 340 followed by 36 zeros. It coexists with IPv4 at the moment, but it is gradually replacing it.
Public vs. Local IP Addresses
IP addresses come in two types: internal, also known as local or private addresses, and external, also known as public addresses. Your external address is provided by your internet service provider (ISP). The website you are visiting needs to know who you are when you browse the internet (for traffic-monitoring purposes). Your ISP connects you to the website and establishes the connection using your external IP address.
When identifying your devices within a corporate office or on a home network, for example, you have a separate IP address. The router, which is the hardware that links a local network to the internet, assigns your computer a local or internal IP address. The router (or cable modem) assigns the internal IP address automatically most of the time.
How does IP address work?
It helps to understand how IP addresses work if you want to troubleshoot why your network might not be functioning or why a specific device is not connecting as you would expect.
Internet Protocol communicates using established protocols to transfer data, much like any other language. Using this protocol, all devices locate, send, and exchange data with other linked devices. Any computer, anywhere in the world, can communicate with any other computer by using the same language.
IP addresses are usually used in a background context. This is how the procedure operates:
- By initially establishing a connection with a network that is online, your device gains access to the internet indirectly through that network.
- That network is most likely your Internet Service Provider (ISP) when you are at home. It will be your workplace network at work.
- Your ISP assigns an IP address to your device.
- Your IP address is used by the ISP to route your online activities back to you. It is their responsibility to issue your device an IP address because they are the ones providing you with internet connection.
- Your home IP address does not follow you when you take your device with you whether you are traveling or otherwise out and about. This is due to the fact that you will be accessing the internet through a different network—the WiFi at a hotel, airport, coffee shop, etc.—and will be using a temporary IP address that has been allocated to you by the establishment’s internet service provider.
How IP addresses are assigned: Dynamic vs. Static
IP addresses can be either temporary (dynamic) or permanent (static). Static IP addresses are different from dynamic IP addresses in that the former can change, while the latter always do.
Businesses use static addresses mainly because their websites and web applications need to be consistently available. However, since you just need your home IP address when you use the internet, it doesn’t have to remain the same.
You will often receive a dynamic IP address from your ISP. Even though it might not happen frequently, your ISP might give you a fresh IP address each time you restart your computer. This also applies to the local IP addresses that your laptop, tablet, or smartphone are assigned by your home wireless router. Every time your router is restarted, these devices may receive a new address.
What is the purpose of IP Address
Managing connections between devices that send and receive data over a network is the function of an IP address. Every device on the internet is uniquely identified by its IP address; without one, communication with them is impossible. IP addresses inform websites about who is connecting and enable computing devices (such PCs and tablets) to communicate with websites and streaming services.
Similar to a postal return address, an IP address serves as both. If you provide a return address on the envelope, you will receive your letter back if it is delivered to the incorrect address after being mailed.
This also applies to emails. Your IP address enables the company’s mail server to send you a bounce notice when you write to an invalid recipient (someone who quit their job and no longer has a company email address), letting you know that your email wasn’t sent to the intended recipient.
Why do you need an IP address?
A device connected to the internet is uniquely identified by its IP address. Most online activities need it, and it allows devices to communicate with each other.
There are two main categories of IP addresses: dynamic and static. The IP addresses that your ISP assigns are static—they never change. Dynamic IP addresses are assigned by DHCP servers and are dynamic in nature.
Dynamic IP addresses are used by most home users. This is because dynamic IP address assignment is more cost-effective for Internet service providers. However, static IP addresses are frequently needed for other uses, such as website hosting and online gaming.
It’s important to understand the differences between and usage for both dynamic and static IP addresses. It allows you to decide if a static IP address is required for your specific needs.
