What is IPv4 transfer?

IPv4 transfer is the procedure by which the rights to IPv4 addresses are transferred from one user to another. The outcome of this process is the updating of RIR databases and the designation of the transferee by the resource’s owner (user). Transfers can occur as a result of the sale or purchase of addresses or through the merger of companies and assets. The legal and procedural aspects of transfers vary depending on the type of addresses (see What is subnet status) and the rules of the RIRs involved in the transfer process.
