What is subnet mask example?

What is subnet mask example?

Example: A class C network would have a subnet mask of 255.255. 255.0 which means that 24 bits are used for the network. In CIDR notation this is designated by a /24 following the IP address.

What is subnet mask and why it is used?

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 is a 29 subnet mask?

/29 — 32 Subnets — 6 Hosts/Subnet. Network # IP Range. Broadcast. .0.

What is subnet mask for dummies?

A subnet mask defines which chunk of an IP address is the host ID and which portion is the subnet network ID. A subnet mask works like a filter with the mask identifying the IP address bits that represent the network ID with a 1, and the bits that represent the host ID with a 0.

What is a subnet mask for WIFI?

A subnet mask will “mask” out the host bits, leaving only the Network ID visible. It also helps define the size of a particular subnet. Most subnet mask with a bit range of 0 to 8 belongs to DSL and T1 IP blocks while the private networks have bit range in the 8 to 24 IP blocks.

Is 255.0 255.0 a valid subnet mask?

A subnet mask distinguishes the network identifier from the host identifier in an IP address, but is not restricted by the same rules as the class-based method. A subnet mask, like an IP address, is made up of four numbers. These numbers can range from 0 to 255. 0.0 is a valid subnet mask as opposed to 255.0.

Does the subnet mask 255.255 255.0 tell a router?

What does the subnet mask 255.255. 255.0 tell a router? The purpose of the part of the mask that reads 255, or all 1s in binary, is to tell a router what part of an IP address is the subnet ID.

What is subnet mask in WIFI?

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).

What is 22 subnet mask?

Subnet Mask Cheat Sheet

	Addresses	Netmask
/ 24	256	255.255.255.0
/ 23	512	255.255.254.0
/ 22	1024	255.255.252.0
/ 21	2048	255.255.248.0

What is 26 subnet mask?

The common subnet mask 255.255. 255.0 is 11111111.11111111. A subnet mask of 255.255. 255.192 is 11111111.11111111. 11111111.11000000 in binary, or 26 ones, hence /26.

What is the subnet mask for WiFi?

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. 255.192, which limits the number of IP addresses to 64.
