What is the subnet mask of 172?
255.255
The address 172.16. 52.63 is a class B address. Its first octet is 172, which is between 128 and 191, inclusive. Class C networks use a default subnet mask of 255.255.
How do you find out which subnet a host belongs to?
To calculate the number of possible hosts per subnet, use the formula 2h – 2, where h equals the number of host bits. The reason two addresses must be subtracted is because of the network address and the broadcast address. There are two ways to determine the number of host bits.
What is the subnet address of 172.16 112.1 25?

What is the subnetwork IP to which host IP address 172.16 66.0 21 belong to?
255.255.248.0
What is the subnet id of a host with an IP address 172.16. 66.0/21? Explanation: A /21 is 255.255. 248.0, which means we have a block size of 8 in the third octet, so we just count by 8 until we reach 66.

How many subnet addresses are there in a network?
Note that each network will have 16 addresses, but 2 of these can’t be used for hosts, so only 14 are usable per subnet (the first and last address of each subnet isn’t allowed because the first is the network and the last is the broadcast). Once you have down the basics you can answer any subnetting question possible.
What is the IPv4 subnet calculator?
IP Subnet Calculator. This calculator returns a variety of information regarding Internet Protocol version 4 (IPv4) and IPv6 subnets including possible network addresses, usable host ranges, subnet mask, and IP class, among others.
What is the difference between host identifier and subnetwork mask?
All hosts on a subnetwork have the same network prefix, unlike the host identifier which is a unique local identification. In IPv4, these subnet masks are used to differentiate the network number and host identifier.
What is the difference between a router and a subnet?
The act of dividing a network into at least two separate networks is called subnetting, and routers are devices that allow traffic exchange between subnetworks, serving as a physical boundary. IPv4 is the most common network addressing architecture used, though the use of IPv6 has been growing since 2006. An IP address is comprised of
