# You asked: What is the first octet range for a class c ip address?

In a class A address, the first octet is the network portion, so the class A address of, 10.1. 25.1, has a major network address of 10. Octets 2, 3, and 4 (the next 24 bits) are for the hosts. Class A addresses are used for networks that have more than 65,536 hosts (actually, up to 16,581,375 hosts!).

Moreover, what is the last octet number for a class C address? In a class C IP address, the first three bits of the first octet are always 1 1 0. And the remaining 21 bits of first three octets complete the network ID. The last octet (8 bits) represent the host ID and allows for 254 hosts per network. Class C network number values begins at 192 and end at 223.

You asked, what is first octet range of class B IP? Class B networks use a default subnet mask of 255.255. 0.0 and have 128-191 as their first octet.

Frequent question, what is a Type C IP address? A Class C address consists of a 24-bit network address and an 8-bit local host address. The first three bits in the network address indicate the network class, leaving 21 bits for the actual network address. … In other words, the first octet of a Class C address is in the range 192 to 223.

Additionally, what is an IP octet? IP addresses consist of a 32-bit number, usually written in dotted-decimal notation. … Each of the decimal numbers in an IP address is called an octet. The term octet is just a vendor-neutral term instead of byte. So, for an IP address of 168.1. 1.1, the first octet is 168, the second octet is 1, and so on.

## What is the last octet of an IP address?

The last octet is the host portion of the IP address. That’s where you’d assign your devices. In this case, you could assign up to 254 hosts. (More on that later.)

## Which octet represent the network portion of a Class C IP address?

Class C. In a Class C IP address, the network portion is represented by the first, second, and third octets; it has 110 in its three leftmost bits.

## Can the last octet of an IP address be 0?

0 or . 255 can never be assigned to hosts. Such “last” addresses of a subnet are considered “broadcast” addresses and all hosts on the corresponding subnet will respond to it.

The IP address range for Class C is 192.0. 0.0 to 223.255. 255.255.

## What is a Class C network?

A Class C network is any network in the 32-bit, IPv4 addressing scheme whose first three bits, the so-called high-order bits, are 110. IPv4 (Internet protocol version four) is the current mainstream addressing protocol for the Internet and other TCP/IP (transmission control protocol/Internet protocol) networks.

## What are the first three bits in a Class C IP address?

In a class C address, the first three bits are class identifiers; the next 21 bits are the network address; and the last eight bits identify the host. There are millions of class C network numbers, but each class C network is composed of fewer than 254 hosts.

## Which of the following is Class C IP address?

The correct answer is 192.168. 5.54. Class C IP addresses range from 192.0. 0.0 to 223.255.

## What is the range of IP address?

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.

## What is the assignable range of values for the first octet for class A IP networks?

What is the assignable range of values for the first octet for Class A IP networks? D. The first octet of Class A addresses ranges from 1 to 126, inclusive; Class B, 128 to 191, inclusive; and Class C, 192 to 223 inclusive. 127 is technically in the Class A range, but it is a reserved address used as a loopback.

## 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.

## What octet determines the class of an IP address?

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. The other two classes are used for other purposes – class D for multicast and class E for experimental purposes.

## What is the size of 1 octets in the IPv4 system?

The octet is a unit of digital information in computing and telecommunications that consists of eight bits.

## What is octet in IPv4?

In the IPv4 portion of the address x is called an octet and must be a decimal value between 0 and 255. The octets are separated by periods. The IPv4 portion of the address must contain three periods and four octets.
