We will discuss these types of addresses in the IP address components lesson.Īn IPv4 host can communicate in different ways: unicast, broadcast and multicast. The value of the IP address must have a value between the network and the broadcast address. The host address is the address assigned to a single host in a network.
It is always the last address in an IP address range. The broadcast address is a special address used to send data to all hosts on a network. It is always the first address in an IP address range. The network address is the address by which we refer a network. In the range of a network, there are three types of IP addresses: network address, broadcast address and host address. We continue in our CCNA certification topic with the types of IP addresses. You can start for example to find out what’s the binary representation of 215? What about 110 or 16? Are you able to calculate the decimal value for 11010011, 00010110, 01110001? This is a requirement in the CCNA exam, and you may have to do some calculations. We write down 1 and from this point we can fill the remaining 3 spaces with 0s. We write 1 and we subtract 32 from 40, getting us 8. We write down 1 and we subtract 128 from 168. Let’s take the same number, 168, and convert it to binary.ġ68 is greater than 128. You continue to make the calculations until you reach 2^0. If your number is lower than the power of 2, you write down 0. If your number is greater, you write down 1 and you subtract that power of 2 from the number. When you calculate the binary value, you take those powers of 2 and compare them with your number.
The decimal to binary conversion is similar to binary to decimal conversion.

Let’s now learn how to convert those numbers from decimal to binary. To get the decimal number you have to sum up those number.įor example, we know that 10101000 is 168. Depending on their position in the octet, they get different values. In the binary system there are only 1s and 0s. Every octet, in its decimal form, can get a value from 0 to 255. In its binary form, 11000000 is the first octet, 10101000 the second, 00001010 the third and 00000001 the last octet. For example, 192 is the first octet, 168 the second, 10 the third and 1 the last octet. For example, the address 192.168.10.1 is a dotted decimal address.
A dotted decimal address is the human representation of the binary address. From our point of view, we use what’s called a dotted decimal address. Routers know how to interpret those numbers, but for a human to understand them would be too difficult. The IP addresses fields are represented in 32 bits. That’s how the routers on the network knows where the packet is coming from and where they must forward the packet. In IPv4 each packet contains a source and destination address. IP enables hosts to communicate with each other at the Network layer.
