What is a 24 CIDR?

CIDR defines which IP addresses, and how many host IP addresses will be allowed on the network. 0.15 and the /24 CIDR, for example. 192.168. 0.15 defines the address prefix, and /24 defines the number of bits reserved for the netmask. This means that the first 24 bits of the IP address are reserved for network routing.

What is the subnet mask for 24?

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 is IP followed by 24?

The subnet mask shows what part is which. /24 means that the first 24 bits of the IP address are part of the Network number (192.168. 0) the last part is part of the host address (1-254).

What is CIDR address?

CIDR is the short for Classless Inter-Domain Routing, an IP addressing scheme that replaces the older system based on classes A, B, and C. A single IP address can be used to designate many unique IP addresses with CIDR. A CIDR IP address looks like a normal IP address except that it ends with a slash followed by a number,…

What is CIDR range?

CIDR is also used for IPv6 addresses and the syntax semantic is identical. The prefix length can range from 0 to 128, due to the larger number of bits in the address. However, by convention a subnet on broadcast MAC layer networks always has 64-bit host identifiers.

What does 24 mean IP?

/24 means that the first 24 bits of the IP address are part of the Network number (192.168.0) the last part is part of the host address (1-254).
