An IPv4 address with a first octet in the range of 128 to 191 falls within the Class B network range. This class is designed for medium to large-sized networks and supports up to 65,536 addresses per network. In binary, Class B addresses start with the bits "10," allowing for a significant number of host addresses while maintaining a reasonable number of available network identifiers.

Class C
Always ends with an octet of 0
An IPv4 address represented in dotted decimal notation consists of four octets, each ranging from 0 to 255. Each octet is 1 byte, so the total size of an IPv4 address is 4 bytes. Thus, an IPv4 address in dotted decimal notation is 4 bytes in size.
The normal format is dotted decimal, where each octet is converted from binary to decimal and separated by a period, thus: 192.168.100.123
The dotted decimal representation of the IPv4 address 11001011.00000000.01110001.11010011 is obtained by converting each octet from binary to decimal. The binary octets convert as follows: 11001011 is 203, 00000000 is 0, 01110001 is 113, and 11010011 is 211. Therefore, the IPv4 address in dotted decimal format is 203.0.113.211.
A complete IP address has 4 octets. MPGMichael We are talking IPv4 because IPv6 uses quintets. There are 4 octets in an IPv4 address. Each octet is separated by a dot (.) Each place has a binary value assigned to it as follows. 128s, 64s, 32s, 16s, 8s, 4, 2s, and 1s place The place values repeat in each octet The place values are read from right to left in binary numbers Within each octet there are 2^8 or 2 to the 8thpower possible addresses. So the math answer is 256. However if you write it out you will see that 128+64+32+16+8+4+2+1 = 255 and 256 is actually carried to the next octet. So there are 255 possible addresses in each octet For example a class C address would look like this 192.168.1.2 or binary 11000000.10101000.00000001.00000010
The first characteristic is that the IPv4 is completely connectionless. The second is that they are media independent and can be unreliable.

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
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
A binary octet refers to a group of eight bits in digital computing and telecommunications. Since each bit can represent two states (0 or 1), an octet can represent 256 different values (from 0 to 255). It is commonly used in networking to represent an IPv4 address, where each of the four segments is an octet. The term highlights the importance of the byte as a fundamental unit of data storage and transmission.
