IPv4: A Fundamental Part of Networking

IPv4 is, as the name suggests, the fourth iteration of the internet protocol (IP). This protocol, along with IPv6, is something that the internet uses for inter-networking with other devices and access points. It is vital to the transfer of data from one device to another. Without it, the internet couldn’t exist.

First created by ARPANET in 1983, IPv4 is still the most frequently used internet protocol today despite successor protocol IPv6 being deployed. IPv4 is a connectionless protocol, meaning that it sends data as individual units in the form of packets. This ensures that data can be sent from one device to another without the need for an established connection. This allows for data to be sent and received at separate times by different devices and still allow successful transmission.

IP Addresses

In order to use internet protocol, devices that are connected to a network are assigned an IP address. An IP address is a unique numerical label that assigns devices their own IDs, as well as transmits the location of the devices for proper data transfer. Depending on the network type (public or private), each device has either a corresponding public and private IP address. Public IPs will change each time a connection is established, whereas private ones only change if the device hasn’t been connected to a network in over 2 weeks.

IP addresses are valuable because they allow devices to access the internet. Because of this, Internet Service Providers (ISPs) and many businesses need them to accommodate and allow device connectivity to the internet. IPv4 addresses are also valuable because they are more compatible with older technology that hasn’t yet been adjusted to receive IPv6 devices. It’s often used as a default IP address for internet connectivity.

Why It Is Valuable

IPV4 transfer is very valuable. Since the onset of IPv6, the range of IPv4 addresses have been completely exhausted –- that is to say that no new unique IPv4 addresses can be created. This had made IPv4 addresses a rare and sought-after commodity by ISPs and end-user organizations. As such, IPv4 may be bought in bulk from the Internet Assigned Numbers Authority (IANA), through Regional Internet Registries (RIR). They can also be bought from an approved IP address broker. IP addresses that are not in use are then are effectively transferred over to the buyer.

How to Transfer an Ipv4 Addresses

As mentioned above, IP addresses can be bought from Regional Internet Registries, such as the American Registry for Internet Numbers (ARIN), or through approved IP address brokers. The transfer is largely a step-by-step process, but with one important difference. Because of the rarity of IPv4 addresses, any transfer request must be based on a “justified need” for the addresses for at least 24 months. This need includes the capacity to demonstrate a business case for the need and ability to use at least 50% of those IP addresses for at least 24 months, and that 50% of all previous addresses are going to be used efficiently. Once such things have been established, it is a simple matter of paying the necessary fees and signing any required documentation to acquire the desired IPv4 addresses.
