ResolverID

ResolverID is a tool designed to identify and resolve the source of Domain Name System (DNS) queries. It operates by intercepting DNS queries and responses, then analyzing the data to determine the origin of the queries. This can be particularly useful for network administrators and security professionals to identify unauthorized DNS queries, detect potential security threats, and monitor network traffic.

The tool works by capturing DNS traffic on a network and then using a database of known DNS resolvers to match the source IP addresses of the queries. If a match is found, ResolverID can provide information about the resolver, such as its location, owner, and any associated security risks. This information can be used to take appropriate action, such as blocking unauthorized queries or investigating potential security breaches.

ResolverID is compatible with various operating systems and can be integrated into existing network monitoring and security systems. It is a valuable tool for organizations that need to ensure the security and integrity of their DNS infrastructure. However, like any tool, it should be used responsibly and in accordance with legal and ethical guidelines.
