Transfer Statistics
According to section 4.0 of "RIPE Resource Transfer Policies", the RIPE NCC publishes a list of all Internet number resources transferred according to the policy.
For transfers of RIPE NCC-distributed resources within the RIPE NCC service region, the list also specifies whether a transfer was due to a change in an organisation's business structure (such as a merger or acquisition).
