With this tool you will be able to look up and visually see a domain’s different DNS records. This tool will query the domain’s DNS for common record types like: A, AAAA, MX, TXT and PTR (rDNS). The results will be displayed in a ‘tree style’ view, providing easy comparison of record types across the authoritative DNS servers.

A DNS (domain name system) tree is a hierarchical representation of domain names organized in a visual layout that resembles a tree or flowchart. The first node DNS tree represents a domain name, and branches represent subdomains and nameservers. Those are then broken up into DNS record types, which are helpful for identifying DNS propagation, resolution, and hierarchy.
DNS hierarchy refers to the organization of domain names in a hierarchical structure within the Domain Name System (DNS). The DNS hierarchy starts with the root domain at the top, followed by top-level domains (TLDs), second-level domains (SLDs), and subsequent subdomains.
We recommend using the DNS tree when making configuration changes, when troubleshooting DNS issues, and when migrating to a new host. Frequency varies for each web project, which can be impacted by your own organization’s IT priorities. If you monitor your DNS regularly, bookmarking this tool can help.
