Whois data cleanup, Sanjaya, APNIC Sec. Synopsis The conversion of the APNIC whois service to RPSL required a large amount of historical data to be imported en masse. APNIC Secretariat has undertaken a detailed analysis of the data, and identified over 25,000 entries which are either no longer needed, or have format problems. The APNIC Secretariat proposes a mechanism to identify and fix these problems, with membership review. This activity is of increasing importance as early registration transfers are undertaken, since some of the data currently in our whois database overlaps with records we need to import from ARIN. It also improves our ability to manage global routing processes, by removing records which conflict with other organizations routing declarations.
