Answer from AI
An IP address (IPv4) consists of 32 bits and is divided into four octets of 8 bits each. It has two main parts:
- Network Part: Defines the network.
- Host Part: Defines a specific device within this network.
The division between the network and host parts is determined by the Subnet Mask. The subnet mask has the same structure (32 bits, 4 octets) and consists of a sequence of ones followed by a sequence of zeros. Ones in the mask correspond to bits of the network part of the IP address, and zeros correspond to bits of the host part.
Example:
- IP address:
192.168.1.10 - Subnet mask:
255.255.255.0
In this example, the first three octets (255.255.255) of the mask correspond to the network part 192.168.1, and the last octet (0) corresponds to the host part 0.10.
IPv6 addresses consist of 128 bits and have a different structure, divided into 8 groups of 16 bits.
Main components of an IP address (IPv4):
| Component | Description | Size (bits) |
|---|---|---|
| Octets | Four groups of 8 bits | 8 (each) |
| Network part | Identifies the network | Varies |
| Host part | Identifies a specific device within the network | Varies |
| Subnet mask | Defines the boundary between the network and host parts | 32 |
