Deep Dive: E8C14
The correct answer is C: Internet Protocol (IP). Nodes in a mesh network have Internet Protocol (IP) addresses. Mesh networks use IP addressing to identify and route data between nodes, just like the internet. In a mesh network, each node has an IP address that uniquely identifies it on the network. Nodes use IP addresses to communicate with each other, routing data through the mesh. The mesh network may use various routing protocols to find paths through the network, but the addressing is based on IP. This allows mesh networks to integrate with the internet and use standard networking protocols. IP addressing is fundamental to how mesh networks operate.
Why Other Answers Are Wrong
Option A: Incorrect. Email addresses are for email communication, not for network node addressing. Mesh networks use IP addresses, not email addresses. Option B: Incorrect. Trust server is not a type of address. Mesh networks use IP addresses for node identification. Option D: Incorrect. Talk group addresses are used in trunked radio systems (like DMR), not for mesh network node addressing. Mesh networks use IP addresses.
Exam Tip
Mesh network addresses = IP addresses. Remember: Nodes in a mesh network have Internet Protocol (IP) addresses. This allows them to communicate and route data through the mesh.

Real-World Example
You're setting up a mesh network node. Your node gets an IP address (like 192.168.1.100) that uniquely identifies it on the mesh network. Other nodes use this IP address to send data to your node, and your node uses other nodes' IP addresses to route data through the mesh. The IP addressing allows the mesh to function like a computer network.
