Understanding CIDR Subnet Mask Notation
| Subnet Mask | CIDR Prefix | Total IP Addresses |
|---|---|---|
| 255.255.252.0 | /22 | 1024 |
| 255.255.248.0 | /21 | 2048 |
| 255.255.240.0 | /20 | 4096 |
| 255.255.224.0 | /19 | 8192 |
What does the slash mean in subnet mask?
The slash and the number following it is just a shorthand way to write a subnet mask. It’s called CIDR (Classless Inter-Domain Routing) notation. It’s also commonly referred to as the prefix length. The number after the slash represents the number of consecutive 1’s in the subnet mask.
What’s the slash after an IP address?
It indicates the subnet mask of the IP. IP has 32 bits, and number after the slash tells you where does the network part end, host part starts. and /24 says that first 24 bits are used for network designation, while last 8 bits are used for various hosts inside that network.
What subnet mask is represented by the 20 slash notation?
The slash notation /20 represents a subnet mask with 20 1s. This would translate to: 11111111.11111111. 11110000.0000, which in turn would convert into 255.255. 240.0.
What is a slash 24?
It represents the CIDR netmask – after the slash you see the number of bits the netmask has set to 1. So the /24 on your example is equivalent to 255.255. 255.0. This defines the subnet the IP is in – IPs in the same subnet will be identical after applying the netmask.
What does 23 mean after an IP address?
Subnet Cheat Sheet – 24 Subnet Mask, 30, 26, 27, 29, and other IP Address CIDR Network References
| CIDR | Subnet mask | # of IP addresses |
|---|---|---|
| /23 | 255.255.254.0 | 512 |
| /22 | 255.255.252.0 | 1,024 |
| /21 | 255.255.248.0 | 2,048 |
| /20 | 255.255.240.0 | 4,096 |
What is 255.255.252.0 subnet mask?
The number of 0s a binary mask has is directly related to the subnet length. Continuing from the example, the subnet for IP address length of the subnet mask 255.255.255.252 is 2. When calculating subnets and subnet masks, there are special numbers that reoccur and remembering these numbers is essential.
What is the subnet mask for 24?
The subnet mask is the classical way of representing which bits are part of the network portion of the address vs. the host bits of the address. The subnet mask for a /24 network is 255.255.255.0 or frequently in hex 0xffffff00.
What is a network mask?
The network mask is what performs all the local magic of dividing an IP network into subnetworks. The network mask for an un-sub-networked IP network number is simply a dotted quad which has all the ‘network bits’ of the network number set to ‘1’ and all the host bits set to ‘0’.
What is netmask 255.255.255.0?
The subnet mask 255.255.255.0 address is the most common subnet mask used on computers connected to Internet Protocol (IPv4) networks. Besides its use on home network routers, you might also encounter this mask on network professional certification exams such as the CCNA.
