## What is subnetwork address?

Table of Contents

Subnet addressing allows an autonomous system made up of multiple networks to share the same Internet address. The subnetwork capability of TCP/IP also makes it possible to divide a single network into multiple logical networks (subnets).

### How do you calculate subnet address?

The first and last addresses are reserved: the first to identify the network and the last to be used as the broadcast address.

1. Find host range.
2. Convert to binary.
3. Calculate the total number of hosts per subnet.
4. Calculate the number of subnets.
5. Verify the total number of subnets.

#### What is the subnetwork address of a host with an IP address of 172.16 66.0 21?

What is the subnet id of a host with an IP address 172.16. 66.0/21? Explanation: A /21 is 255.255. 248.0, which means we have a block size of 8 in the third octet, so we just count by 8 until we reach 66.

How is IPv6 address calculated?

IPv6 addresses consist of 128-bit addressing and are represented in hexadecimal notation. In the above diagram, each dash represents 4 bits. Therefore 4+4+4+4 = 16 bits in each block. And 16 x 8 = 128-bit addressing.

What is the subnetwork address for a host with IP address 200.10 5.68 28?

What is block size? What is the subnetwork address for a host with the IP address 200.10. 5.68/28? /28 means 11111111.11111111.

## How do I find my network address?

Find your IP address in Windows

1. Select Start > Settings > Network & internet > Wi-Fi and then select the Wi-Fi network you’re connected to.
2. Under Properties, look for your IP address listed next to IPv4 address.

### Why is subnet mask always 255?

A subnet mask is a 32-bit number created by setting host bits to all 0s and setting network bits to all 1s. In this way, the subnet mask separates the IP address into the network and host addresses. The “255” address is always assigned to a broadcast address, and the “0” address is always assigned to a network address.

#### How many IP addresses are in a 24?

### How do I create an IPv6 address?

The following procedure describes how to configure global unicast address.

1. Select a VLAN.
2. Select the corresponding VLAN.
3. Select the IPV6 tab and expand the IP Address Assignment accordion.
4. Enable Use Static addresses.
5. Click + in IPv6 addresses.
6. In the Add New IPV6 addresses pop-up, select Global unicast for Address Type.

#### What subnetwork does a host on a network belong to if its IP address is 172.16 45.14 30?

Given IP address is 172.16. 45.14/30 => NID is 30 bits and HID is last 2 bits. Subnet mask = 255.255. 255.252 (Subnet Mask is obtained by replacing all NID bits by 1 and all HID bits by 0).

What would be the broadcast and lowest host addresses for the subnet 10.16 3.65 23?

The lowest host address in the subnet is 10.16. 2.1 255.255. 254.0. The last valid host address in the subnet is 10.16.

What is the 127.0 0.1 address used for?

0.1, the IP address of the local computer. This IP address allows the machine to connect to and communicate with itself. Therefore, localhost (127.0. 0.1) is used to establish an IP connection to the same device used by the end-user.

Is IPv6 faster than IPv4?

Web and cloud services provider, Akamai, measured the speed of IPv6 vs. IPv4. They found, “Sites load 5% faster in median and 15% faster for the 95% percentile on IPv6 compared to IPv4.” That means for some people who are pursuing high speed, IPv6 is indeed a better choice.
