1. A method for forming a filtered topology mapping, comprising:

  • collecting topology data of a network;

    storing said topology data;

    receiving filtering criteria from a user, wherein the filtering criteria comprises a selection of one or more object attributes of the stored topology data;

    filtering the stored topology data using said filtering criteria; and

    forwarding said filtered topology data to the user,wherein the collecting of topology data comprises;

    searching for nodes in a pre-defined number of internet protocol (IP) addresses;

    repeating the search for a predefined number of hops;

    determining Layer-2 and Layer-3 connectivity from any of the nodes discovered during the search;

    correlating Layer-2 and Layer-3 address data; and

    determining network connectivity by examining the internet protocol (IP) addresses of each of the nodes discovered during the search,wherein the Layer-2 connectivity is used when available, and Layer-3 connectivity is used when the Layer-2 connectivity is not available.
