This could be a couple of things, but you are likely referring to TCP/IP protocol broadcasts. A broadcast address is when a data packet is sent to a special address to which all nodes on the network are supposed to accept and optionally respond to. While a broadcast address is defined for the entire network, this is not implemented in practice. For an IP subnet, the last address in the subnet's address space is the broadcast.
For example, if my subnet is defined as 192.168.1.0/24 (very common for consumer network hardware including Wi-Fi), this defines the following: the network itself is identified as 192.168.1.0, the subnet mask is 255.255.255.0 (24 binary 1s in a row), the usable host addresses are 192.168.1.1 through 192.168.1.254, and the broadcast address is 192.168.1.255.

What is the difference between a Network address and Broadcast 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.
Which subnet mask would be assigned to the network address of192.168.32.0 to provide 254 useable host addresses per subnetwork?
255.255.255.0 is the subnet mask that provides 256 addresses of which the first (0) and last (255), the broadcast addresses are excluded, leaving 254 usable addresses.
IP subnet masks allows for up to 30 hosts per subnet?
255.255.255.224 will select a network of 32 IP addresses, with the lowest reserved as the network identifier, and the highest as the broadcast address, leaving 30 usable host IP addresses.
What is broadcast ID?
A broadcast ID, often referred to as a broadcast address, is a special network address used to send data packets to all devices within a specific subnet or network segment. Instead of targeting individual IP addresses, packets sent to the broadcast address are received by all devices on that network, facilitating communication and data sharing. In IPv4 addressing, the broadcast address is typically the highest address in a subnet. For example, in the subnet 192.168.1.0/24, the broadcast address would be 192.168.1.255.
Why last subnet can't be used when subnetting a network?
The last subnet in a subnetted network is typically reserved for broadcast addresses, which are used to send data to all devices on that subnet. This means that the broadcast address cannot be assigned to any individual device. As a result, the last subnet is effectively unusable for host assignments, limiting the number of available subnets for actual device connections.
How many bits are in 172.168.2.0 26 subnet?
The subnet mask for a /26 subnet indicates that the first 26 bits are used for the network portion, leaving 6 bits for the host portion. In this case, the subnet 172.168.2.0/26 can accommodate 2^6 = 64 addresses, but only 62 are usable for hosts (subtracting the network and broadcast addresses). Thus, there are 26 bits designated for the network and 6 bits for hosts within this subnet.
What is the broadcast address on IPv4 networks?
The broadcast address on IPv4 networks is the subnet address, padded on the right with ones. For example, if the subnet address is 192.168.x.y, with a subnet mask of 255.255.0.0, then the broadcast address is 192.168.255.255.
What are two invalid IP addresses on each subnet?
The first and last IP address on each network. e.g. In a classful class C network, the IP addresses x.x.x.0 and x.x.x.255 are invalid and cannot be assigned to a network interface card. x.x.x.0 is the network address for the subnet. x.x.x.255 is the network broadcast address for the subnet.
What is 192.168.1.0 subnet mask 24?
The IP address 192.168.1.0 with a subnet mask of 255.255.255.0 (or /24) indicates a Class C network. This subnet allows for 256 IP addresses, ranging from 192.168.1.0 to 192.168.1.255, where 192.168.1.0 is the network address and 192.168.1.255 is the broadcast address. This configuration provides 254 usable host addresses (from 192.168.1.1 to 192.168.1.254) for devices within the network.
What netmask would you use to allow for 310 hosts in a subnet?
To accommodate 310 hosts in a subnet, you would need a netmask that provides at least 512 IP addresses, as the number of usable host addresses is calculated as (2^{(32 - n)} - 2), where (n) is the number of bits used for the network portion. A /23 netmask (255.255.254.0) allows for 512 total IP addresses, resulting in 510 usable addresses after subtracting the network and broadcast addresses. Thus, a /23 netmask is suitable for a subnet requiring 310 hosts.
What is the broadcast address for the host IP of 172.16.66.021?
That depends on the subnet's subnet mask.
What is the network broadcast address of 216.14.55.137?
To find the network broadcast address for the IP address 216.14.55.137, you need to know its subnet mask. Assuming a common subnet mask of 255.255.255.0 (or /24), the network address would be 216.14.55.0, and the broadcast address would be 216.14.55.255. Therefore, if using a /24 subnet, the broadcast address for 216.14.55.137 is 216.14.55.255. If a different subnet mask is used, the broadcast address would change accordingly.
