Test Whois Database
APNIC also operates a test database where users may learn how to use the APNIC Whois Database.
The test database is for training and learning only. The sample data in the test database is not a copy of the data in the APNIC Whois Database and changes to the test database are not reflected in the APNIC Whois Database. The APNIC Test Whois Database is not an authoritative source of whois data and no value should be put on the data in the test database.
