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.
The largest address in IPv4 is 255.255.255.255. This address is reserved for broadcasting to all hosts on a local network, and it represents the highest possible value for each of the four octets in the IPv4 address format. The total range of IPv4 addresses spans from 0.0.0.0 to 255.255.255.255, with the largest address being a special case used for broadcast purposes.
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.
