DNS Tests and Tools
The D-Zone DNS Configuration Test is a free tool that lets you analyze the health of your DNS by traversing from the root to the domain. It groups the results into basic, address, connectivity, consistency, DNSSEC, delegation, name server, syntax, and zone. The DNS test helps you optimize the configuration of your authoritative name servers.

TSIG is not a requirement and many organizations choose to specify IP address-based permissions between DNS name servers. However, as the DNS is increasingly targeted by bad actors on the Internet, TSIG is a recommended design consideration
