I am assuming that 10.0.0.1/24 is your local subnet? If so, try pinging 10.0.0.29, then type arp -g at a DOS prompt on a Windows box. This will spit out the MAC address of the device on 10.0.0.29.<br />
Now, go to the link below, and enter that MAC address. This will give you some information about the manufacturer of the device. (You could also sniff the MAC address with Wireshark of course.)<br />

It may or may not provide a useful clue.

10.0.0.1/24 is on 1 Ethernet port. 192.168.0.1 is on another. <br />

Wireshark

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

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
