It is up to members to find and organise a transfer of IPv4 address space. How they decide to do this is up to them. The RIPE NCC will not be involved in the process of reaching an agreement between the parties involved in the transfer of IPv4 address space. The responsibility for reaching an agreement rests solely with the offering and receiving parties.

Some members may decide to use a broker to find an organisation offering or seeking address space and to help facilitate the process by advising on the processes and policies that need to be followed.

Whatever the case, it is important that anyone involved in IPv4 transfers understands the relevant RIPE Policies and that any transfers are reflected in the registry.

Brokers who are facilitating the transfer of IPv4 address space are welcome to contact the RIPE NCC for clarification, and can email  to find out more.

Some common questions concerning brokers and other issues are answered in the FAQ section.
