How do I find the host and network portion of an IP address?
The subnet mask signifies which part of the IP address is network and which part is host. The subnet mask is compared to the IP address from left to right, bit for bit. The 1s in the subnet mask represent the network portion; the 0s represent the host portion.
What is the network portion of the address?
The network part specifies the unique number that is assigned to your network. The network part also identifies the class of network that is assigned. In Figure 5–3, the network part occupies two bytes of the IPv4 address.
How can you identify the network portion of an IP address?
The subnet mask is used in IPv4 and IPv6 to show what part of the address is the network portion and what part of the address is the host portion. In IPv4 there are three default subnet masks corresponding to the three classes of IP addresses (as illustrated earlier).
How do I find my host portion?
To calculate the number of possible hosts per subnet, use the formula 2h – 2, where h equals the number of host bits. The reason two addresses must be subtracted is because of the network address and the broadcast address. There are two ways to determine the number of host bits. 1.
What is the host portion?
Host Part. This is the part of the IP address that you assign to each host. It uniquely identifies this machine on your network. Note that for each host on your network, the network part of the address will be the same, but the host part must be different.
What is the host portion in 172.16 12?
The 172.16. 0.0/12 private network can be interpreted either as a block of 16 class B network IDs or as a 20-bit assignable address space (20 host bits) that can be used for any sub-netting scheme within the private organization.
What is a host portion?
An IP address is 32 bits long and made up of two components, a network portion and a host portion. The host (or node) address is used to identify a particular device attached to the network. The IP address is generally represented using the dotted-decimal notation, where 32 bits are divided into four octets.
What is network address and host address in IP address?
An IP address consists of two components: the network address and the host address. The network address is used to find the subnet in which the computer or the device is located and the host address is used to find the computer or the device in the subnet.
What is the subnet mask 172.16 0.0 16?

Is 172.16 a private IP range?
The 172.16. 0.0/12 private network can be interpreted either as a block of 16 class B network IDs or as a 20-bit assignable address space (20 host bits) that can be used for any sub-netting scheme within the private organization. 0.0/12 private network allows the following range of valid IP addresses: 172.16.

How many subnets and hosts are provided by the network address of 172.16 0.0 19?
Solution(By Examveda Team) This is a Class B address, so that is only 3 subnet bits, but it provides 13 host bits, or 8 subnets, each with 8,190 hosts.
What are the parts of an IP address?
For this purpose, an IP address is recognized as consisting of two parts: the network prefix in the high-order bits and the remaining bits called the rest field, host identifier, or interface identifier (IPv6), used for host numbering within a network.
What is host IP address?
A host’s IP address is the address of a specific host on an IP network. All hosts on a network must have a unique IP address. This IP address is usually not the first or the last IP address in the range of network IP addresses as the first IP address and last IP address in the range of IP addresses are reserved for special functions.
How do I look up my IP?
There are many ways to look up your IP address in Windows 10. Most Windows old-timers do it the hard way, by opening Network and Sharing Center (click, click, click), finding the list of network adapters (click), and then looking at the details for each adapter (click, click, click). But all that clicking isn’t necessary, as it turns out.
How do I find my ISP address?
Click the Start button, type “cmd” in the Search box at the bottom of the Start menu and press “Enter” to launch the Command Prompt tool. 2. Type “ipconfig /all” and press “Enter” to view the Internet Protocol configuration.
