## Is Class A IP address private or public?

Address ranges to be use by private networks are: Class A: 10.0. 0.0 to 10.255. 255.255.

## What is the valid range of a Class A IP address?

Class Range Network Address
A 0-127 xxx
B 128-191 xxx . xxx
C 192-223 xxx . xxx . xxx

What is the difference between Class A and Class B IP addresses?

If the first bit is 1 and the second bit is 0, the address is a class B address. If the address is written in decimal format, the first number determines the address. 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.

### How many subnets are in Class A?

This mask provides you with only four subnet bits, or 16 subnets (14 if you’re not using subnet zero) with 1,048,574 hosts each. The valid subnets are 256-240=16, 32, 48, 64, 80, etc., all the way to 224.

### How many networks are in Class A?

Class Leading bits Number of networks
Class A 0 128 (27)
Class B 10 16,384 (214)
Class C 110 2,097,152 (221)
Class D (multicast) 1110 not defined

How many Class A IP addresses are there?

In a Class A network, the first eight bits, or the first dotted decimal, is the network part of the address, with the remaining part of the address being the host part of the address. There are 128 possible Class A networks.

#### How do you subnet a Class A?

The Class A subnet mask is 255.0. 0.0. Accordingly, Class A IP addresses are best used to serve incredibly large networks. In comparison to Class A, Class B IP addresses are better suited to serving smaller networks since they reserve 14 bits for a network, which leaves only 18 bits for hosts.

#### What is 23 subnet?

What is the subnet mask of Class A?

255.0.0.0
The Class A subnet mask is 255.0. 0.0. Accordingly, Class A IP addresses are best used to serve incredibly large networks. In comparison to Class A, Class B IP addresses are better suited to serving smaller networks since they reserve 14 bits for a network, which leaves only 18 bits for hosts.

## How can you identify the IP class of a given IP address?

You can determine which class any IP address is in by examining the first 4 bits of the IP address. Class A addresses begin with 0xxx, or 1 to 126 decimal. Class B addresses begin with 10xx, or 128 to 191 decimal. Class C addresses begin with 110x, or 192 to 223 decimal. Class D addresses begin with 1110, or 224 to 239 decimal.

## What are the five different classes of IP addresses?

TCP/IP defines five classes of IP addresses: class A, B, C, D, and E . Each class has a range of valid IP addresses. The value of the first octet determines the class. IP addresses from the first three classes (A, B and C) can be used for host addresses.

How does an IP address identify the class to which it belongs?

An IP address consists of two parts, one identifying the network and one identifying the node, or host. The Class of the address determines which part belongs to the network address and which part belongs to the node address. All nodes on a given network share the same network prefix but must have a unique host number.

### How many host for class an IP address?

Class A Public Address IP Range: 1.0.0.0 to 126.0.0.0 First octet value range from 1 to 127 Subnet Mask: 255.0.0.0 (8 bits) Number of Networks: 126 Number of Hosts per Network: 16,777,214

Is Class A IP address private or public? Address ranges to be use by private networks are: Class A: 10.0. 0.0 to 10.255. 255.255. What is the valid range of a Class A IP address? Designing Your IP Addressing Scheme Class Range Network Address A 0-127 xxx B 128-191 xxx . xxx C 192-223 xxx…
