What's the meaning of 10.0.0.1/24 address of my computer (from the ip addr – command)?

  1. Why is it 1/24 and not 0/8?

  2. Why is it using the 10.0.0 range and not 192.168.10?

Best Answer

Thought I would expand on this with a few examples

/8 = 255.0.0.0

/16 = 255.255.0.0

/24 = 255.255.255.0

/32 = 255.255.255.255

192.168.1.0/24 = 192.168.1.0-192.168.1.255

192.168.1.5/24 is still in the same network as above we would have to go to 192.168.2.0 to be on a different network.

192.168.1.1/16 = 192.168.1.0-192.168.255.255

When you have a network you lose two IP addresses one for broadcast and one for the network. The first IP is reserved to refer to the network while the last ip of the range is reserved for the broadcast address.
