What is true about subnet mask?

A subnet mask is a number that defines a range of IP addresses available within a network. A single subnet mask limits the number of valid IPs for a specific network. Multiple subnet masks can organize a single network into smaller networks (called subnetworks or subnets).

Is subnet mask always the same?

Subnet masks always work from left to right. Devices are said to be within the same subnet if their IP Address starts with the same digits, but ends with a different set of digits. ... If the subnet mask is 255.255. 255.0, then the first three octets of all devices must be the same.

What is the purpose of a subnet mask quizlet?

The subnet mask identifies the network and host portion of an IP address. It is used by hosts to identify the destination IP address as either local or remote and is also used by routers to determine the path to route packets.

Which of the following is the role of subnet mask?

The subnet mask is used by the TCP/IP protocol to determine whether a host is on the local subnet or on a remote network. In TCP/IP, the parts of the IP address that are used as the network and host addresses aren't fixed. Unless you have more information, the network and host addresses above can't be determined.

How is subnet mask determined?

A subnet mask is a 32-bit number created by setting host bits to all 0s and setting network bits to all 1s. In this way, the subnet mask separates the IP address into the network and host addresses. The “255” address is always assigned to a broadcast address, and the “0” address is always assigned to a network address.

Why is the subnet mask important in determining the network address?

A subnet mask tells the computer what part of the IP address is the network portion of the address and what part identifies the host address range, which are addresses that are assigned to host computers on that network. ... Subnetting breaks a large network into smaller networks by extending the length of the subnet mask.

What happens if subnet mask is wrong?

If the netmask is wrong, the program tries to directly access sites where it has to go through the router, or vice versa. The netmask defines, which part of the IP-address is used as address for the network and which part is used for the workstations. Both IPs are in the same net.

Can different subnet masks communicate?

A subnet is just a range of IP addresses. All the devices in the same subnet can communicate directly with one another without going through any routers. ... Suppose my IP address is 192.168. 101.15 and my subnet mask is 255.255.

What is the purpose of a subnet mask in an IP address and mask combination?

Explanation: The subnet mask depicts the portion of the IP address that indicates the network from the portion of the address that indicates the host address on the network.

Which subnet mask is commonly used in Class A networks to make them the size of a Class C network?

Which subnet mask is commonly used in class A networks to make the, the size of a class C network? 255.255. 255.0. How many subnets are created by the subnet mask 255.255.

How long is a subnet mask quizlet?

Subnet masks are always 32 binary digits long.

How many octets does a subnet mask have quizlet?

Subnet IDs are calculated via what's known as a subnet mask. Just like an IP address, subnet masks are 32-bit numbers that are normally written now as four octets in decimal.

What is the purpose of subnetting when using IPv4 addressing what role does subnet mask play in subnetting of IPv4?

The quick definition: Subnetting is the process of taking a network and splitting it into smaller networks, known as subnets. It's used to free up more public IPv4 addresses and segment networks for security and easier management.

What is subnet mask Computer hope?

Short for subnetwork mask, a subnet mask is data used for bitwise operations on a network of IP addresses that is divided into two or more groups. This process, known as subnetting, divides an IP network into blocks of logical addresses. Subnetting can improve security and help to balance overall network traffic.

How do the subnet mask and Supernet mask differ from a default mask in Classful addressing?

Answer In subnetting, a large address block could be divide into several contiguous groups and each group be assigned to smaller networks called subnets. In supernetting, several small address blocks can be combined to create a larger range of addresses.

Which of the following is a valid subnet mask?

0.0 is a valid subnet mask as opposed to 255.0. 255.0. The 255.255. 0.0 subnet mask identifies the network identifier as the first two digits of the IP address.

What is binary subnet mask?

A subnet mask, like an IP address, is 32 bits in length. ... Subnet masks are composed of some number of 1 bits followed by enough 0 bits to form a 32-bit value. The bit positions with a 1 correspond with the bit positions in the IP address that are part of the network ID.
