How can you identify the host 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.

How does a router identify the network and host 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).

What IP addresses are in a range?

By even casual observation, you’ll likely have noticed that there are several IP address ranges that are special, including:

  • 10.0. 0.0/8 (10.0. 0.0 – 10.255. 255.255)
  • 172.16. 0.0/12 (172.16. 0.0 – 172.31. 255.255)
  • 192.168. 0.0/16 (192.168. 0.0 – 192.168. 255.255)

How do you determine the number of IP addresses in a range?

The formula to calculate the number of assignable IP address to CIDR networks is similar to classful networking. Subtract the number of network bits from 32. Raise 2 to that power and subtract 2 for the network and broadcast addresses. For example, a /24 network has 232-24 – 2 addresses available for host assignment.

How do I find a broadcast address from an IP address?

Another short cut for broadcast address calculation after getting netwotk address is:

  1. calculate total no of hosts (in this case it is 2^12 = 4096)
  2. Divide it by 256(in this case it is 16) and add the result – 1(in this case 15) in *corresponding octet(in this case second octet i.e. 32+15=47) and make other octet 255.

How do I find my host IP address Windows 10?

Windows 10: Finding the IP Address

  1. Open the Command Prompt. a. Click the Start icon, type command prompt into the search bar and press click the Command Prompt icon.
  2. Type ipconfig/all and press Enter.
  3. The IP Address will display along with other LAN details.

What is a host address of IP?

IP addresses: Networks and hosts. An IP address is a 32-bit number. It uniquely identifies a host (computer or other device, such as a printer or router) on a TCP/IP network. IP addresses are normally expressed in dotted-decimal format, with four numbers separated by periods, such as 192.168. 123.132.

What is the host bit in IP address?

Host bits are the portion of an IP address that identify a specific host in a subnet. The subnet mask determines how much of the address is used for network bits and host bits. For example, an IP (v4) address of 192.168. 0.64/26 has a 6-bit host portion, because 26 out of 32 bits are reserved for the network portion.
