A "same network IP address" refers to a situation where multiple devices on the same local network share the same first few octets (numbers) in their IP addresses, indicating they belong to the same network, but each device has a unique last octet to differentiate them individually; essentially, the only difference between their IP addresses is the "host identifier" part, allowing them to communicate directly with each other.
Key points about same network IP addresses:
Identifying a same network:
To check if two IP addresses are on the same network, compare the first few octets (numbers separated by dots) - if they match, they are likely on the same network.
Subnet mask importance:
The subnet mask determines which parts of an IP address represent the network and which parts represent the host.
Unique host identifier:
While multiple devices on the same network share the same network portion of the IP address, each device has a unique "host identifier" (usually the last octet) to distinguish it.
Example:
IP address 1: 192.168.254.1 [ nvr poe switch]
IP address 2: 192.168.254.72 [ ip camera ]
In this example, both devices are on the same network because the first three octets ("192.168.1") are identical.
