What is IPv4 and how can you use it?


As the use of the internet has grown exponentially, the demand for IP addresses has increased significantly. However, with the depletion of Internet Protocol version 4 (IPv4) addresses, businesses are now required to adopt alternative solutions to support their networks. In this article, we will discuss how companies can transition to IPv6 and other possible solutions.


What is IPv4?

IPv4 is the protocol responsible for assigning IP addresses on the internet, and it has almost been depleted. This is a significant issue for businesses that rely on IP addresses for their network and services. One possible solution is Network Address Translation (NAT), which enables a company to connect a private network to the internet using a single public IP address. This reduces the number of IP addresses required and can reduce costs for businesses.


What about IPv6?

Another option for businesses is to use IPv6, the successor to IPv4, which provides significantly more IP addresses than IPv4. IPv6 addresses consist of 128 bits, whereas IPv4 addresses only have 32 bits. This enables the use of a large number of unique combinations of IP addresses. However, transitioning to IPv6 requires the company to update their networking equipment and software to IPv6-compatible versions.


Dual stack

A dual-stack solution is also a viable option for businesses, allowing them to support their network and services with both IPv4 and IPv6 addresses. This can facilitate a transition period while IPv6 is still being implemented and IPv4 is being phased out.



As IP addresses become increasingly scarce, buying or leasing IPv4 or IPv6 addresses through IP brokers, such as Prefixbroker.com, is an option that businesses can consider.

Effective management of IP addresses is crucial for businesses in the digital age. IPv4 is almost exhausted, and businesses should explore alternative solutions such as NAT, IPv6, or dual-stack. Selecting the right solution is essential, taking into account the specific needs of the business and anticipating future growth and changes in demand for IP addresses. Adopting the right solution enables a company to make efficient and effective use of IP addresses and reduce the cost of managing their network.
