System and method for generation of simplified domain name server resolution trees

A non-transitory computer readable medium having stored thereon instructions for causing a processing circuitry to execute a process for generation of a consolidated network resolution tree, the process comprising:

• receiving a target fully qualified domain name (FQDN);
• creating at least one tentative equivalence class (TEC) containing all the internet root domain name servers (DNS);
• processing the at least one TEC to determine respective consolidated edges and vertices;
• retrieving nameservers from domain registration records;
• determining whether additional TECs are to be generated for the retrieved nameserver(s);
• processing all new TECs to determine respective consolidated edges and vertices, when it is determined that new TECs are to be generated;
• and
• generating a resolution tree for display based on the consolidated edges and vertices.

A system for generating and representing a consolidated resolution tree of a network, comprising:

• a processing circuitry;
• a network interface for interfacing to a network, the network interface communicatively connected to the processing unit;
• a memory, the memory communicatively connected to the processing circuitry and containing their instructions that, when executed by the processing circuitry, configure the system to:
• receive a target fully qualified domain name (FQDN);
• create at least one tentative equivalence class (TEC) containing all the internet root domain name servers (DNS);
• process the at least one TEC to determine respective consolidated edges and vertices;
• retrieve nameservers from domain registration records;
• determine whether additional TECs are to be generated for the retrieved nameserver(s);
• process all new TECs to determine respective consolidated edges and vertices, when it is determined that new TECs are to be generated;
• and
• generate a resolution tree for display based on the consolidated edges and vertices.
