Why are IP addresses divided into classes?
IP addresses are divided into five classes that are identified by the value of the first octet (the first decimal number).
The system of IP address classes was developed for the purpose of Internet IP addresses assignment.
The classes created were based on the network size.
For large networks with many devices..
How many devices can be on a subnet?
A maximum of 254 devices can be used in this subnet. If the subnet mask is 255.255. 0.0, then the first two octets of all devices must be the same.
How do you subnet?
255.248 or /29.STEP 1: Convert to Binary.STEP 2: Calculate the Subnet 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. … STEP 3: Find Host Range. … STEP 4: Calculate the Total Number of Subnets and Hosts Per Subnet.
What are the 3 classes of subnet mask?
The three default subnet masks are 255.0. 0.0 for Class A, 255.255. 0.0 for class B, and 255.255. 255.0 for Class C.
What is a Class C subnet?
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. So: IP address 192.168.
How many 20 subnets are in a 16?

What is a Class A IP address?
In Internet Protocol version 4 (IPv4), a unicast address in the range 1.0. 0.1 to 126.255. 255.254. Class A addresses are identified by a beginning 0 bit.

What are the 3 major classes of an IP network?
Currently there are three classes of TCP/IP networks. Each class uses the 32-bit IP address space differently, providing more or fewer bits for the network part of the address. These classes are class A, class B, and class C.
How many hosts are in a class A subnet?

What is a Class A subnet mask?
Class A networks use a default subnet mask of 255.0. 0.0 and have 0-127 as their first octet. The address 10.52. 36.11 is a class A address. Its first octet is 10, which is between 1 and 126, inclusive.
Which of the following is an example of class A subnet mask?
The valid subnets in this example are 16, 32, 48, 64, 80, 96, 112, 128, 144, 160, 176, 192, 208, 224. As another example, if you had a Class A subnet mask of 255.255. 240.0, you’d use the mask on the second and third octets minus 256.
What are Class A IP addresses used for?
Class A IP addresses are used for huge networks, like those deployed by Internet Service Providers (ISPs). Class A IP addresses support up to 16 million hosts (hosts are devices that connect to a network (computers, servers, switches, routers, printers…etc.)
What is a 192.168 IP address?
Using 192.168. 192.168. 0.0 is the beginning of the private IP address range that includes all IP addresses through 192.168. … One common IP address assigned to home routers is 192.168. 1.1. This IP address is used because the router is on the 192.168.

What is difference between subnet and subnet mask?
Subnet Mask — A 32-bit number used to distinguish the network and host portions of an IP address. Subnet or Subnetwork — A smaller network created by dividing a larger network into equal parts.
