IPv4 addresses have 4 octets, each octet separated by a period. For example, at this time, one of Yahoo's servers has an ip address of 67.195.160.76.
An IP address consists of four octets. Each octet is an 8-bit segment, which can represent a value from 0 to 255. In IPv4, these four octets are typically written in decimal format and separated by dots, such as in the address 192.168.1.1.
32 Bits 4 Octets with 1 Byte each(8 Bits)
IPv4 is 32 bit. 4 octets of 8 bits each.
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.
32 bits in a IPv4 address
Because the octets equal to 0 and 255 are reserved
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 TcP IPv4 ip address has 32 bits.
The address 255.255.255.255 is considered the greatest IPv4 address because it is the highest possible value for each of the four octets in the 32-bit address space. It is a special address known as the limited broadcast address, used to broadcast messages to all hosts on the local network segment. Unlike regular IP addresses assigned to devices, it cannot be assigned to any individual host. Hence, it represents the maximum value in the IPv4 addressing scheme.
