Alhálózatokat

Alhálózatokat, often translated as subnetting, is a process used in computer networking to divide a larger network into smaller, more manageable segments called subnets. This division is achieved by reallocating bits from the host portion of an IP address to the network portion. By doing so, the network administrator can create multiple distinct subnets from a single IP address range.

The primary purpose of subnetting is to improve network efficiency and security. Smaller subnets reduce broadcast traffic, as broadcasts are typically confined to a single subnet. This can lead to better network performance by decreasing congestion. Additionally, subnetting allows for the implementation of more granular security policies. Network administrators can apply different access control lists (ACLs) and firewall rules to different subnets, isolating traffic and preventing unauthorized access between segments.

Another benefit of subnetting is simplified network management. Smaller networks are easier to monitor, troubleshoot, and administer. It also aids in IP address conservation, particularly in IPv4 networks where addresses are a limited resource. By allocating specific address ranges to different subnets, organizations can make better use of their available IP addresses.

The process of subnetting involves using a subnet mask, which is a 32-bit number used in conjunction with an IP address to determine which part of the address represents the network and which part represents the host. The subnet mask effectively defines the boundaries of each subnet.
