Arne Kiessling gave a presentation on registry data quality and protecting internet resources. He discussed the importance of registering IP address assignments in the RIPE Database to declare their use and provide contact information. This helps maintain accurate registry data and protects resources. Kiessling also covered issues that can arise if contact details are outdated, such as unauthorized resource transfers. The RIPE NCC performs regular Assisted Registry Checks to keep registry data clean and support members.
