This tool checks reverse DNS zone data (namely NS and SOA resource records) to ensure that your reverse delegation is correctly set up.

It is a useful way of ensuring that the domain name object submitted into the AfriNIC WHOIS database is consistent with reverse zone delegation information.

The checker takes some time to query the DNS zone file and compile any problems it may find so please be patient when using this tool. Once it is completed, a report will be generated and displayed with problem codes and links to their descriptions.
