What is a subnet mask in simple terms?
Table of Contents
A subnet mask is a way to divide an IP network. You can think of it as the area code of your phone number. In simple terms, subnet masks are used in networks to split them into two or more subnetworks, making them easier to manage.
What is subnet mask in IP address?
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. To better understand how IP addresses and subnet masks work, look at an IP address and see how it’s organized.
What does the subnet mask 255.255 255.0 tell a router?
Answer: A subnet mask of 255.255. 255.0 allows for close to 256 unique hosts within the network (since not all 256 IP addresses can be used). This is the default subnet mask used by Class B networks and provides up to 65,536 IP addresses (256 x 256).
What is subnet mask with example?
Subnet masks are also expressed in dot-decimal notation like an IP address. For example, the prefix 198.51. 100.0/24 would have the subnet mask 255.255. 255.0. Traffic is exchanged between subnetworks through routers when the routing prefixes of the source address and the destination address differ.
How do subnets work?
Subnetting works by applying the concept of extended network addresses to individual computer (and another network device) addresses. An extended network address includes both a network address and additional bits that represent the subnet number.
What does 24 mean after IP?
2.0/24”, the number “24” refers to how many bits are contained in the network. From this, the number of bits left for address space can be calculated. As all IPv4 networks have 32 bits, and each “section” of the address denoted by the decimal points contains eight bits, “192.0.
What does 255.255 mean?
255.255. 255.255 is a special broadcast address, which means “this network”: it lets you send a broadcast packet to the network you’re connected to, without actually caring about its address; in this, is similar to 127.0. 0.1, which is a virtual address meaning “local host”.
How does a subnet work?
How do you find your IP address and subnet mask?

What is the difference between IP address and subnet mask?
Open Command Prompt by searching for CMD
How to calculate subnet mask of IP address?
The octet in which a subnet exists 1st octet:/1 to/8 2nd octet:/9 to/16 3rd octet:/17 to/24 4th octet:/25 to/32
How are IP addresses and subnet masks related?
IP addresses: Networks and hosts. An IP address is a 32-bit number.
