An IP address is a necessary unique identifier for each internet-connected device in the digital age. These addresses are essential to the internet’s operation and device-to-device communication. However, have you ever thought about the distribution of IP addresses? We’ll go deep into the IP address allocation procedure in this blog, covering all the important information.
What is an IP address?
For your computer or other Internet-connected device, an IP address (Internet Protocol address) is similar to your home address. It’s a unique string of digits, such as 192.168.1.1, divided by periods. This facilitates the identification of every Internet-connected gadget.
An IP address allows computers to communicate and receive data from other computers, much like your home address does for postal delivery. It is necessary because it guarantees that the Internet understands where to send the email or where to deliver the data from a website when you go online and ask it to do so.
Importance of IP Addresses
Enables communication over the internet
An IP address acts like a digital postman. Imagine that you are mailing a letter. To get in touch with the relevant individual, you need to know their address. Similar to this, your device needs the recipient’s or website’s correct IP address in order to send an email or access a webpage when you’re online.
Using this address guarantees that your email gets to the correct recipient or website. Without IP addresses, it would be impossible to direct information to the right place on the internet.
Identifies Devices
Your device’s internet identity is determined by its IP address. Your gadget is uniquely identified online by its IP address, much like your fingerprint is. This uniqueness is important, particularly in the modern world where millions of gadgets are online. It guarantees that your device, and not someone else’s, gets the information or service you want online.
Allows location tracking and customization
Have you ever wondered why some internet services aren’t available in your area or how websites choose which language to display? This is the use of IP addresses. They give you an idea of roughly where your gadget is connecting to the internet.
Websites use this location-specific data to modify their content, such as displaying news items that are relevant to your location or products that can be transported to you. Your online experience is enhanced by this customisation, which makes it more useful.
What is IPv4?
IPv4 stands for Internet Protocol version 4. It’s similar to the Internet’s postal service in that it uses rules to help guide data to the right place. The four digits that make up an IPv4 address are separated by dots.
An IPv4 address can seem like this, for example: 189.168.1.1. Any number set has a possible range of 0 to 255. There are many possible combinations using this structure. There is still a cap on the number of addresses it may create.
What does IPv4 do?
One particular version of this Internet Protocol is called IPv4. It is in charge of locating devices on a network and arranging data flow between them. Each device connected to the Internet needs a unique IP address, which is a string of numbers that designates that particular device. These addresses are created by IPv4.
Being one of the major Internet protocols, IPv4 is important. Without IPv4, data transmission and reception across the Internet would be disorderly and chaotic. It’s like having postal codes and addresses but no addresses for your mail system.
What is IPv6?
Internet Protocol version 6 is known as IPv6. It is the newest of the Internet Protocol. The older version of IPv4, which has been there since the early days of the Internet, was meant to be replaced by IPv6.
Why do you need IPv6?
Increased IP address availability is the primary driver behind IPv6. Similar to phone numbers, that is. As more individuals have phones, we need unique phone numbers. The requirement for additional distinct IP addresses increases in tandem with the number of devices connecting to the Internet.
Roughly 4.3 billion addresses can be supported by the 32-bit IPv4 addressing method. We have already used them all, even though it seems like a lot. There is a higher limit of 340 undecillion addresses that IPv6 can handle with its 128-bit addressing.
Role of IP Address Allocation
The process of giving each device on a network a unique IP address is known as IP address allocation. This guarantees that other people can identify and interact with each device. The worldwide network of linked gadgets that we refer to as the internet could not operate without this procedure.
Who manages IP Address Allocation?
IANA, the Internet Assigned Numbers Authority: IANA, a division of the Internet Corporation for Assigned Names and Numbers (ICANN), is at the top of the hierarchy. IANA is in charge of managing the worldwide distribution of IP addresses as well as other vital resources like protocol assignments and DNS root zones.
Regional Internet Registries (RIRs): Large IP address blocks are assigned by IANA to Regional Internet Registries (RIRs), who then manage and disperse them over specified geographical areas. There are five RIRs:
- ARIN (American Registry for Internet Numbers) for North America
- RIPE NCC (Réseaux IP Européens Network Coordination Centre) for Europe, the Middle East, and parts of Central Asia
- APNIC (Asia-Pacific Network Information Centre) for Asia and the Pacific region
- LACNIC (Latin America and Caribbean Network Information Centre) for Latin America and parts of the Caribbean
- AFRINIC (African Network Information Centre) for Africa
Internet service providers (ISPs) and local internet registries (LIRs): IP addresses are distributed by RIRs to LIRs, which are often big ISPs or organizations. LIRs then redistribute IP addresses to end users or smaller companies.
IP addresses allocation process
Submission of Requests: When an organization needs IP addresses, it sends a request to the relevant RIR. Usually, this request includes details regarding the use of the IP addresses as well as the reason they are required.
Justification and Review: The RIR reviews the request to make sure the company actually needs the addresses it has asked for. By taking this action, IP address hoarding can be avoided and effective use of address space can be guaranteed.
Allocation and Approval: The RIR assigns the IP addresses following the request’s approval. Depending on what the needs of the company are, this can be IPv4, IPv6, or both. Prefix blocks are used during the allocation process.
Registration: The assigned IP addresses are registered in a public database that stores details about the address block and the organization. This database is usually kept up to date by the RIR. In order to manage the worldwide IP address space, this transparency is crucial.
Assigning to End Users: ISPs and LIRs allot a lesser percentage of their allotted IP address blocks to end users, which can include people or companies. Either a dynamic (temporarily assigned, frequently using DHCP) or static (permanently allocated) assignment can be made.
Challenges in IP address allocation
IPv4 Exhaustion: Due to the internet’s rapid growth, IPv4 addresses are running out. IPv6 offers an alternative, but the shift has been slow, posing problems for ISPs and businesses that continue to use IPv4.
Efficient Usage: It is important to make sure that IP addresses are used effectively. RIRs have put measures in place to avoid address hoarding while promoting IPv6 adoption.
Geopolitical Problems: The distribution of IP addresses can occasionally give rise to geopolitical conflicts, particularly in areas where demand exceeds supply.
Future of IP Location
The need for IP addresses will only increase as we head toward a fully connected future with an ever-increasing number of devices and the Internet of Things (IoT). Adoption of IPv6 is important for satisfying this requirement. Additionally, to guarantee that the internet continues to be scalable and available to everyone, improvements in IP address management and allocation processes will be necessary.
