An IP address is always a set of four numbers like that. Each number can range from 0 to 255. So, the full IP addressing range goes from 0.0. 0.0 to 255.255.

Besides, What is a class B subnet?

Class B networks use a default subnet mask of 255.255. 0.0 and have 128-191 as their first octet. The address 172.16. 52.63 is a class B address. Its first octet is 172, which is between 128 and 191, inclusive.

Keeping this in mind, How do you write an IP address range? CIDR notation is written as the IP address, a slash, and the CIDR suffix (for example, the IPv4 ” 10.2. 3.41/24 ” or IPv6 ” a3:bc00::/24 “). The CIDR suffix is the number of starting digits every IP address in the range have in common when written in binary. For example: ” 10.10.

How do IP address ranges work?

IP addresses are expressed as a set of four numbers — an example address might be 192.158. 1.38. Each number in the set can range from 0 to 255. So, the full IP addressing range goes from 0.0.

What is a 24 IP range?

What is the difference between Class A Class B and Class C networks?

For any given IP address, the address class is easy to determine. … If the first number is between 0 and 127 inclusive, the address is class A. If the first number is between 128 and 191 inclusive, the address is class B. If the first number is between 192 and 223 inclusive, the address is class C.

What does the subnet mask 255.255 255.0 tell a router?

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). The largest Class A networks use a subnet mask of 255.0.

How many subnets are in Class A?

The two bits added to the network part from the host part can have four possible values in second octet of a Class A network , 00, 01, 10, and 11. That means, we can get four networks if we do a 2-bit subnetting on a Class A network. Ths subnet mask to use for Class A network 2-bit subnetting is 255.192. 0.0.

How do you read an IP address range with a slash?

Slash notation is a compact way to show or write an IPv4 subnet mask. When you use slash notation, you write the IP address, a forward slash (/), and the subnet mask number. To find the subnet mask number: Convert the decimal representation of the subnet mask to a binary representation.

What are the 4 parts of an IP address?


IP Address Components

  • Address Class. Early in the development of IP, the IANA (Internet Assigned Numbers Authority) designated five classes of IP address: A, B, C, D, and E. …
  • Default Subnet Mask. …
  • The Network Field. …
  • The Host Field. …
  • Non-default Masks. …
  • The Subnet Field.

How do CIDR ranges work?

In CIDR notation, IP addresses are written as a prefix, and a suffix is attached to indicate how many bits are in the entire address. The suffix is set apart from the prefix with a slash mark. For instance, in the CIDR notation 192.0. 1.0/24, the prefix is 192.0.

How do you read a 24 IP range?


IPv4

  1. Convert the subnet mask to binary. In this example, the binary representation of 255.255. 255.0 is: 11111111.11111111. …
  2. Count each 1 in the subnet mask. In this example, there are twenty-four (24).
  3. Write the original IP address, a forward slash (/), and then the number from Step 2. The result is 192.168. 42.23/24.

What does 24 mean in subnetting?

hello Allan49, the /24 is referring to the subnet mask. / 24 indicates that the first 24 bits of the address are masked (255.255.255.0). a /16 would translate into 255.255.0.0.

What is a Class A network?

Class A. Class A addresses are IP addresses that are assigned to network devices, such as computers, and include all addresses in which the first bit of the first octet is set to 0 (zero). … For Class A networks, the first octet represents a network ID that is defined in the address by a subnet mask.

What kind of networks use a Class A or Class B or Class C IP address typically?

What kind of networks use a Class A or Class B or Class C IP address typically? Class A IP address is used for a network with large number of hosts. Class C IP address is used for a network with less number of hosts. Class B IP address is used for a network with medium number of hosts.

What is a Class C network used for?

Classes of IP Addresses

Class Purpose
A These are designed to be used in very large companies like Google.
B These are designed to be used in medium-sized companies
C They designed to be used in small-sized companies.
D They are not used in the public sector, instead being reserved for multicast addressing

What does a subnet mask tell a router?

A subnet mask determines which parts of the IP address are network and host identifiers. It is a 32-bit number that distinguishes each octet in the IP address.

What is subnet mask on router?

A subnet mask is a number that defines a range of IP addresses available within a network. A single subnet mask limits the number of valid IPs for a specific network. … Systems within the same subnet can communicate directly with each other, while systems on different subnets must communicate through a router.

How many subnets are in a class C?

255.224. The three bits added to the network part from the host part in the last octet can have eight possible values. Those eight possible values are 000, 001, 010, 011, 100, 101, 110 and 111. That means, we get eight subnets if we do a 3-bit subnetting for a Class C network.
