Description

Feature description
This analyzer searches a list of local DHCP scopes, to determine if the IP address it is analyzing belongs to any of them.

Describe the solution you'd like
Given an IP address, and the list of configured DHCP scopes within the organization, if the IP address is in any of the scopes, annotate the IP observable with the name of the matching scope.

The analyzer is made to search scope information exported from Microsoft DHCP servers, but it reads the information from CSV files, which could perhaps be constructed from the configuration of other DHCP servers.

Research direction

Start by reading the repository's existing analyzer structure and CSV-based analyzers, then determine how an IP observable is annotated; done means a DHCP analyzer can match an IP against Microsoft DHCP scope data and report the matching scope name.
