DNS Check
The DNS Check tool will probe an internet domain for critical configuration failures and perform general health checks to help optimize a domain's DNS settings and check propagation. The report will show errors and warnings based on internet standard RFCs and best practices. Categories of tests to be performed include Parent (TLD) Nameservers, Domain Nameservers delgated for the domain being tested, Start of Authority (SOA) records, Mail Exchange (MX/email), website/HTML, and DNSSEC. It defaults to IPv4 but also supports IPv6 testing when in IPv6 mode.
