A Brief Overview of the IPv4 Market


The IPv4 market has evolved due to the growing demand and limited supply of IP addresses. This article explores how this market works.

Understanding IPv4 Addresses

What are IPv4 addresses?

Internet Protocol version 4 (IPv4) addresses are unique identifiers assigned to devices on an IP-based network to facilitate internet communication. An IPv4 address, composed of 32 bits divided into four octets, is typically represented in a dotted-decimal format (e.g., Each octet ranges from 0 to 255, allowing for approximately 4.3 billion unique addresses. These addresses serve as destinations for data packets, enabling accurate routing to the intended device. The size of an IPv4 address block can vary, often being a power of 2, such as 256 addresses (2^8) for a /24 block.

A regional Internet registry (RIR) is an organization that manages the allocation and registration of IP addresses within a region of the world.

Classification of IPv4 Addresses

IPv4 addresses are classified into five classes: A, B, C, D, and E. Each class has a specific range of addresses reserved for different purposes, such as public or private networks. Class A addresses are used for large networks, Class B for medium-sized networks, and Class C for small networks. Class D is used for multicast groups, and Class E is reserved for future use or research and development purposes.

IPv4 Address Exhaustion


The rapid growth of the internet and the increasing number of digital devices have led to a shortage of available IP addresses. This phenomenon, known as IPv4 address exhaustion, has been a concern since the 1980s, leading to the development of various techniques to extend the life of IPv4, such as subnetting, Classless Inter-Domain Routing (CIDR), and Network Address Translation (NAT). Understanding the challenges caused by IPv4 address scarcity is essential for individuals and organizations involved in networking.

The Market for IP Addresses

Overview of the IP Address Market

The IP address market involves the transfer of limited IP addresses from one organization to another. IP Brokers connect sellers and buyers, with prices determined by demand, availability, block size, and region. 

The IP address market operates much like any other market with supply and demand dynamics. The supply comes from organizations that have unused or underutilized IP addresses, while the demand comes from organizations that need additional IP addresses to grow their networks. The price of IP addresses in this market can fluctuate based on these supply and demand dynamics, as well as other factors such as the reputation of the IP addresses and the size of the address block.

Transfer of IP Addresses

The transfer of IP addresses involves transferring rights of exclusive use of IP addresses from the seller to the buyer. Organizations can sell their surplus addresses, while others can purchase them. Qualified IP Brokers like IPv4.deals usually facilitate these transactions.

The process of transferring IP addresses typically involves several steps. 

  1. First, the buyer and seller agree on the terms of the sale, including the price and the size of the address block. 
  2. Next, the seller submits a transfer request to the relevant RIR, providing the necessary documentation to prove that they are the rightful owners of the addresses. 
  3. The RIR then reviews the request and, if approved, updates the registry to reflect the buyer as the new owner of the addresses.

Factors Influencing the IPv4 Market

Key factors in the IPv4 market include:

1. IP Address Pricing

The cost of IPv4 addresses can vary significantly depending on several factors. These include the demand in the marketplace, block size, and reputation: 

  • Demand: As the supply of IPv4 addresses becomes more limited, the cost tends to increase. Global macroeconomic conditions also play a huge role in this factor.
  • Block Size: Larger contiguous blocks tend to be more valuable than smaller blocks or fragmented blocks.
  • Reputation: The price of IP addresses can be influenced by the reputation of the addresses. For example, addresses that have been involved in spamming or other malicious activities may have a poor reputation and may be less valuable in the market. 

It’s important to note that the IP address market can be somewhat opaque, with prices not publicly available or varying widely. This lack of transparency can make it challenging to understand the fair market value of IP addresses. To navigate this, potential buyers can get in touch with the team at IPv4.deals.

2. IPv4 Transfer Policies and Regulations

IP transfer policies and regulations govern the transfer of IP addresses between organizations. The policies are defined by Regional Internet Registries (RIRs) and require organizations to demonstrate a justified need for the addresses and comply with regional boundaries.

Each RIR has its own transfer policies and procedures, so it’s important to understand the rules of the relevant RIR before proceeding with a transaction. Some RIRs require the buyer to demonstrate a need for the addresses, while others have more relaxed policies.

To further understand these procedures, here are detailed transfer processes:

By familiarizing yourself with these processes, you can ensure a smoother and more compliant transfer.
