Deep Dig is an advanced DNS lookup tool designed with DNS tracing functionalities and a comprehensive query history feature. Users can quickly access DNS records by specifying record types, custom servers, ports, and other parameters, much like the command line tool known as dig. It accommodates numerous record types, including A, AAAA, ANY, CNAME, PTR, NS, MX, SOA, and SRV, while also offering the "-t type" option for tailored queries. Moreover, users can leverage the "+trace" and "+all" options within either the query or hostname fields for enhanced information retrieval. The tool also provides the ability to specify a custom DNS server and port through the "-h host" and "-p port" options, supporting various DNS server types in the process. In addition, it features automatic DNS querying to local multicast IP addresses and can effectively query Bonjour/mDNS servers. Deep Dig also facilitates queries to LLMNR servers and carries out reverse DNS (PTR) lookups automatically when users input an IPv4 or IPv6 address. Another noteworthy aspect is its ability to automatically determine the country linked to an IP address or domain name during resolution. This extensive array of features establishes Deep Dig as an essential asset for network administrators and IT professionals, enhancing their efficiency and capability in managing DNS-related tasks.
