Which octets are used for the network address and for host address in class A class b class c?

There are4 octets in an IP address as shown below:Octet1.Octet2.Octet3.Octet4Every IP class has different allocation of network and host ID.For class A, the network and host IDs' allocation is as follows:Network.Host.Host.HostFor class B, the network and host IDs' allocation is as follows:Network.Network.Host.HostFor class C, the network and host IDs' allocation is as follows:Network.Network.Network.HostYou may go to the following link get more info on IP address classes and their IDs:www.iphow.x10hosting.com


How does the IP address indicate the network?

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.


network portion of these addresses: 209.240.80.78?

This is a class C address. The network portion is the first three octets, so it would be 209.240.80.0.


What is the network portion of 177.100.18.4?

This is a class C address. The network portion is the first three octets, so it would be 209.240.80.0.


How many octets are in a Class C IP address?

24 bits (8 bits per octet, so 3) are used for the network portion of a class C IP address

Which octet represents the network portion of a class c ip address?

The last 3 octets represent the host portion in a class A address.


What class is the IP address 210.23.67.102?

Class B Class A are octets beginning in numbers 1-126 Class B are octets beginning in numbers 128-191 Class C are octets beginning in numbers 192-223


Assuming no subnetting what are valid Class B host addresses?

A classful class B network has a network range of 128 - 191. For host addresses, anything that is legal for an IP address in the last 2 octets would be a valid host address for a class B with no subnets.


Which class of IP address supports the most networks?

A class C network supports the most networks - the first three octets or 24 bits gives the largest grouping of networks.


What is class B address range?

A class B address range is all the addresses that start with binary 10, or decimal 128-192. As originally defined, the first two bytes (octets) indicate the network; the last two bytes are reserved for the host. That is, a class B network has about 65,000 available addresses.
