In classful addressing the class of the address can be found by shifting the copy of the address bits to the right?

Shifting to the right won't accomplish anything. To find the class of the address, look at the first octet in the address. You can either look for the range of addresses for a class, or look at the first 3 bits in the first octet: First octetAddress Class0-127Class A128-191Class B192-223Class C224-239Class D240-255Class E 0nnnnnnn. First octet class A range (first bit is 0) 10nnnnnn. First octet class B range (first bits are 10) 110nnnnn. First octet class C range (first bits are 110) It is easiest just to look at the range.


Which ipv4 network class address contains a first octet in the range of 128 to 191?

class b


Is 191.76.43.10 a valid routable class C address?

No, because the range for class C addresses is 192 - 223, and the first octet of the address 191.76.43.10 is a class B address.


In IPv4 addressing an IP address whose first octet is in the range of 192-223 belongs to a class?

Class C


Subnet specifications classes?

The classes are based on what range the first octet of the ip address falls in. Class A: 0-127 Class B: 128-191 Class C: 192-223


Why are IP address classified into classes?

For classful addressing, the first octet identifies the class to which it belongs. There is also a way of looking at the first few bits of the first octet, but that makes it more difficult. For an IpV4 address, you have 4 octets for the IP address. Looking at the first octet, to determine the range, use the following: 1 - 126 class A 127 local loopback address 128 - 191 class B 192 - 223 class C 224 - 239 class D 240 - 254 class E


Examples of class A IP address?

An example is 10.0.0.1. An IP address consists of four numbers, separated by dots (so there are three dots in total). Since each of the number represents a byte (or "octet"), each of these numbers is in the range from 0 to 255. Any IP address in which the first of these four numbers is in the range from 0 to 127 is considered to be a "Class A" address. (In the binary representation, that means that the first bit is equal to zero.)


Is the octet range for class E 240-254?

46


How do you identify a class of IP address and its corresponding subnet mask?

Look at the first octet value and check the corresponding range. 1-126 class A, subnet mask 255.0.0.0 128-191 class B, subnet mask 255.255.0.0 192-223 class C, subnet mask 255.255.255.0


What class does the IP address 193.222.18.217 belong to?

If the first byte is in the range 192-223, that's a class C address.


How big are the network and host ID fields for a Class A address?

A class A address is one of the IPv4 class-full networks. There are 3 of these class-full networks in IPv4; class (A, B, and C). The entire IPv4 address range is 32 bits long. The address range is broken up into 4 x (8 bits) referred to as octets, and then giving the whole 32 bit address range. The classes are defined as follows… Class A = reserve the first octet, or 8 bits for network addresses and leave the remaining three for host addresses. Reserving the addresses for the network is also referred to as the network mask. In other words do not assign any address in the reserved, first octet, to a host. Class A = 11111111.00000000.00000000.00000000 also known as a /8 bits reserved for net Class B = 11111111.11111111.00000000.00000000 also known as a /16 bits reserved for net Class C = 11111111.11111111.11111111.00000000 also known as a /24 bits reserved for net So the answer is; a class A network has an 8 bit field for the network, and a 24 bit field for the host


What is the decimal range of the first octet of all possible Class C IP addresses?

Class B - 128 - 191
