What are subnets in IP?

A subnet, or subnetwork, is a segmented piece of a larger network. More specifically, subnets are a logical partition of an IP network into multiple, smaller network segments. The Internet Protocol (IP) is the method for sending data from one computer to another over the internet.

How many subnets are in a IP address?

Subnet Cheat Sheet – 24 Subnet Mask, 30, 26, 27, 29, and other IP Address CIDR Network References

CIDR Subnet mask # of usable IP addresses
/27 30
/26 62
/25 126
/24 254

How do you find the subnet of an IP address?

To calculate the IP Address Subnet you need to perform a bit-wise AND operation (1+1=1, 1+0 or 0+1 =0, 0+0=0) on the host IP address and subnet mask. The result is the subnet address in which the host is situated.

What is 28 subnet mask?

/28 — 16 Subnets — 14 Hosts/Subnet. Network # IP Range. Broadcast. .0.

What is a 31 subnet?

31-bit Subnet Mask (/31) A 31-bit subnet mask is often used for an interface that is the endpoint of a point-to-point network. The use of 31-bit subnet masks for IPv4 point-to-point links is described in RFC 3021. For Router A is connected via Fast-ethernet 0/0 having ip 192.168.

How many subnets are there?

To calculate the number of possible subnets, use the formula 2n, where n equals the number of host bits borrowed. For example, if three host bits are borrowed, then n=3. 23 = 8, so eight subnets are possible if three host bits are borrowed.
