Identify a non-computer network device?

Question

I\'m current working on a program that scans my network and discoveres computers and devices on the network. I use various operations to find data on the devices I discover,

Answer 1

In general you cannot find out much about a device from it's IP.Using the MAC address of the host, you could determine the manufacturer of the Network adapter. The first half of MAC addresses are assigned by manufacturer.

You could try using nmap.

Nmap ("Network Mapper") is a free open source utility for network exploration or security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. Nmap runs on most types of computers and both console and graphical versions are available. Nmap is free software, available with full source code under the terms of the GNU GPL.
