Block Policy Inheritance
The IP address 169.255.255.0 is part of the larger address block designated for link-local addresses in the Internet Protocol version 4 (IPv4). This specific address is technically reserved and is not typically assigned to hosts on a network. Instead, link-local addresses are used for communication within a local network segment. In practice, addresses in the 169.254.0.0/16 range are automatically assigned to devices when they cannot obtain an IP address from a DHCP server.
Class D IP addresses, which range from 224.0.0.0 to 239.255.255.255, are designated for multicast groups rather than traditional host addressing. As such, they do not support subnetting in the same way as Class A, B, or C addresses, since they are not intended for individual host allocation. Subnetting is primarily used to create multiple networks from a single larger network, which is not applicable to Class D. Therefore, subnetting a Class D block is not possible or meaningful in conventional networking.
Medium-sized corporations typically do not want a block of Class C addresses because they often require more IP addresses than a single Class C block can provide. A Class C block offers only 256 IP addresses (with 254 usable), which may be insufficient for their needs as they expand or deploy various services. Additionally, managing multiple Class C networks can complicate network management and increase overhead. Instead, they may prefer larger blocks or a more efficient allocation of IP addresses through techniques like subnetting or using private IP addresses with NAT.
No. If you have one IP per customer, you don't need to create smaller subnets. (You won't have enough addresses though - the first and last addresses of the block will be the network and broadcast addresses and won't be useable. You'll only have 1022 usable addresses)
One major block of addresses reserved for special purposes is the IPv4 experimental address range 240.0.0.0 to 255.255.255.254. Currently, they cannot be used in IPv4 networks. However, these addresses could be used for research or experimentation.

The network address in a block of addresses is the first address in the range that identifies the network itself. It is used to route traffic within that network and is not assigned to any individual device. For example, in the IP address block 192.168.1.0/24, the network address is 192.168.1.0. This address allows devices within the same subnet to communicate with each other.
IP addresses that begin with 185 belong to the range designated for the IPv4 address space, specifically within the 185.0.0.0 to 185.255.255.255 range. These addresses are often used by various organizations and can be assigned to websites, servers, and other devices on the internet. The specific use and ownership of these addresses can vary, as they are allocated by regional internet registries.

This process is known as subnetting. An Internet Service Provider (ISP) takes a large block of IP addresses and divides it into smaller subnets to efficiently allocate resources and manage network traffic. By assigning these smaller subnets to individual customers, the ISP can optimize the use of IP addresses while ensuring each customer has sufficient connectivity. This method enhances network organization and improves overall performance.
