2552552540

2552552540 is most commonly encountered in networking when written with dotted decimal notation as 255.255.254.0. It represents an IPv4 subnet mask that reserves the first 23 bits for the network portion and leaves the remaining 9 bits for host addresses. In CIDR notation, this mask is written as /23.

As a subnet mask, 255.255.254.0 is used to divide an IP address into a network and host portion, enabling a balance between the number of subnets and the number of hosts per subnet. A /23 subnet provides 2^9, or 512, total addresses. After accounting for the network and broadcast addresses, there are 510 usable host addresses within that subnet.

A typical example is the network 192.168.0.0/23, which spans 192.168.0.0 to 192.168.1.255. In this range, 192.168.0.0 is the network address and 192.168.1.255 is the broadcast address; usable host addresses run from 192.168.0.1 to 192.168.1.254. This mask is commonly used in medium-sized networks where more than a single /24 is required but a /22 would allocate too many addresses.

255.255.254.0 is not an IP address itself; rather, it is a configuration parameter used by routers and hosts to determine which portion of an IP address identifies the network. It is part of IPv4 CIDR-based subnetting, standardized for efficient IP address allocation.
