Mell What is first octet in 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!).

What is the first octet range for a Class C address quizlet?
The first octet of Class C addresses is in the range of 192 to 223. The first octet of Class A addresses range from 1-126.
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.
What are Class C IP addresses used for?
Classes of IP Addresses

Which of the following are Class C IP addresses?
Class C networks use a default subnet mask of 255.255. 255.0 and have 192-223 as their first octet. The address 192.168. 123.132 is a class C address.
Which IP address is a Class C address quizlet?
The IP address range for Class C is 192.0. 0.0 to 223.255.
What does each number mean in IP address?
An IP address is typically written in decimal digits, formatted as four 8-bit fields separated by periods. Each 8-bit field represents a byte of the IP address. This form of representing the bytes of an IP address is often referred to as the dotted-decimal format.
How do I know what class An IP address is?
You can identify the class of an IP address by looking at its first octet. Following are the ranges of Class A, B, and C Internet addresses, each with an example address: Class A networks use a default subnet mask of 255.0. 0.0 and have 0-127 as their first octet.
What is the range of Class C IP addresses?
Class C: Class C IP address always has its first bits as 110, next 21 bits as a network address and following 8 bits as the host address. The range of IP addresses is the first block from 192.0.0.0 to 192.0.0.255 and last block from 223.255.255.0 to 223.255.255.255. This means that it allows 2^21 networks and 2^8 hosts per network.
Which is the first octet of a Class C network?
Its first octet is 172, which is between 128 and 191, inclusive. Class C networks use a default subnet mask of 255.255.255.0 and have 192-223 as their first octet. The address 192.168.123.132 is a class C address. Its first octet is 192, which is between 192 and 223, inclusive.
Which is the first octet of an IP address?
Thus the first octet ranges from 1 – 127, i.e. Class A addresses only include IP starting from 1.x.x.x to 126.x.x.x only. The IP range 127.x.x.x is reserved for loopback IP addresses.
What’s the range of IP addresses for a network?
This Class IP address always has its first bit as 0, next 7 bits as a network address and following 24 bits as the host address. The range of IP addresses is 0.0.0.0 to 127.255.255.255. This means that it allows 2^7 networks and 2^24 hosts per network. This class of IP address is used for the very large network. Ex.
