The four octets make up a complete address. The first part refers to a network, the remainder an individual computer in a host; however, the exact size of this "first part" may vary.
Assuming we are talking IPv4, the split between network and host is determined by the subnet mask. In binary, where there is a "1" it is network, where there is a "0" it is host. A+ pg. 870: A: 1st octect: Network; 2nd,3rd,and 4th: Host B: 1st and 2nd octects: Network; 3rd and 4th octets:Host C: 1st,2nd,3rd octects:Network; 4th octect: Host
No, because first three octets are suppose to be same and they are not.
The first octet determines what class of network you are located on. From that, you can determine how many of the octets represent the network address, and which part represents the client or host portion. IP addresses in version 4 (iPv4) are divided into two segments: the network id and the host id. Knowing the range of network class addresses will help: Class A is 0 - 126 and uses only the first octet for the network portion Class B is 128 - 191 and uses the first two octets for the network id Class C is 192 - 223 and uses the first three octets for the network id An example would be: 192.168.1.5 is a class C address, so we use the first three octets for the network id. This gives a network id of 192.168.1.0 and a host id of 5 in that network.
This is a class C address. The network portion is the first three octets, so it would be 209.240.80.0.
3 octet
the answer should be B
The imaginary one? IPv4 address octets are never greater than FF(hex) which converts to 255 (decimal). So 7528 is not a valid number.
The UAA, or Universally Administered Address, is the most commonly used type of MAC address. This address is assigned to the network adapter when it is manufactured. The first three octets define the manufacturer, while the second three octets vary and identify the individual adapter. All network adapter manufacturers have their own code, called the Organizationally Unique Identifier (OUI).

Since a subnet mask is used to separate the network id from the host id, any 1 bits indicate the network portion and the 0 bits indicate host portion. As an example, in the subnet mask: 255.255.0.0 This indicates the first two octets are used for the network, and the last two octets (ipV4) are used for host portion of an address.
