What are the two main parts of a network mask?
A subnet mask is used to divide an IP address into two parts. One part identifies the host (computer), the other part identifies the network to which it belongs.
What should my network mask be?
Most home networks use the default subnet mask of 255.255. 255.0. However, an office network may be configured with a different subnet mask such as 255.255. Large networks with several thousand machines may use a subnet mask of 255.255.
Is subnet mask always 255?
All subnet masks must end in 0, 128, 192, 224, 240, 248, 252, 254, or 255—the values of each bit position as they are “turned on” left to right in any octet. 0.0 is a valid subnet mask, as is 255.255. 248.0 and 255.255. 255.252.
What do you need to know about subnet mask?
Generally, an IP address is made up of network bits and host bits: So generally, subnetting does two things: it gives us a way to break up networks into subnets, and allows devices to determine whether another device/IP address is on the same local network or not. A good way to think about subnetting is to picture your wireless network at home.
Which is the subnet mask of 192.168.0.101?
Another way to express this is with a network ID, which is just the network portion of the IP address. So the network ID of the address 192.168.0.101 with a subnet mask of 255.255.255.0 is 192.168.0.0. And it’s the same for the other devices on the local network ( 192.168.0.102, 192.168.0.103, and so on).
What is the mask for a Class A IP address?
For Class A IP addresses, the first octet (8 bits / 1 byte) represent the network ID, and the remaining three octets (24 bits / 3 bytes) are the host ID. Class A IP addresses range from 1.0.0.0 to 127.255.255.255, with a default mask of 255.0.0.0 (or /8 in CIDR).
What is the easiest mask to use to satisfy the criteria?
– You have been allocated a class B network address of 135.1.0.0 and and need to create 4 subnets each with around 200 hosts what is the easiest mask to use to satisfy the criteria? Easiest is to sub net on a byte boundary which would mean a subnet mask of 255.255.255.0 This would allocate 8 bits for the subnet and 8 bits for the host.
