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.
mAC ADDRESS its actually network addresses.
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)
An address that can only be used on the internal network
In computer networking, a node refers to a connection point. It has two types of addresses, a network address and a physical address.
A MAC address is not considered logical; it is a physical address. It is a unique identifier assigned to network interfaces for communications on a local network segment and is hardcoded into the network hardware. Unlike logical addresses, such as IP addresses, which can change based on the network configuration, MAC addresses remain constant for a device's network interface.
Network layer
Layer 3 network addresses are logical addresses and can be easily changed by software.
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.
A class C address.
When you set up a sub network you decide upon the subnet mask and this determines the network address (all zeros in the subnet portion of the address) and the broadcast address (all ones in the subnet portion of the address). When you assign the host addresses in your subnet, then you use the addresses between the network address and the broadcast address.
The administrator can set up a Local Area Network (LAN) behind a firewall in which he can assign whatever IP address block he wishes. The firewall and router will then need to be configured to Network Address Translate (NAT) the 'hidden' internal IP addresses used on the LAN to the one assigned by the ISP when network traffic needs to leave the LAN.
