Hi all,<br />
<br />
I have been left a total network mess, the last fellow in my position has left prior to my start date and effectively there is no network discovery being done.<br />
I need to find out what IP addresses are in use, and what subnets are configured on each VLAN, etc.<br />
<br />
The network is mostly cisco gear. Any tips or suggestions would be most welcome.

How to map a network......software, tips?

Network analysis is the process of identifying and remediating the processes and systems within a network, including performance, connectivity and security. The process is performed through the use of tools developed for monitoring and analyzing network activity. Network problems that involve finding an optimal way of doing something are studied under the name combinatorial optimization. Examples include network flow, shortest path problem, transport problem, transshipment problem, location problem, matching problem, assignment problem, packing problem, routing problem, Critical Path Analysis and PERT (Program Evaluation & Review Technique).

Network Analysis

Network Operations includes asset management, help-desk supervision, security and user policies, infrastructure administration and anything else that affects the operation of your network. Discussions will include those of best practices in platforms, configurations, performance, security and accounting.

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
