How are the 32 bits of an IP address organized in a typical large network?
How are the 32 bits of an IP address organized in a typical large network? IP addresses are organized in network Classes A, B, and C depending on the size of the organization. In Class A the first octet is the network part while the rest are the hosts.

What is the smallest subnet mask?
31.255. Note that for every bit increase, the size of the subnet doubles in length, along with the number of hosts. The smallest tick mark represents 8 bits, which contains a subnet with 256 hosts–but since you can’t use the first and last IP addresses, there are actually only 254 usable hosts on the network.
How many IPs is a 16?

What should my subnet mask be?
Most home networks use the default subnet mask of 255.255. 255.0. However, an office network may be configured with a different subnet mask such as 255.255. Large networks with several thousand machines may use a subnet mask of 255.255.
How do you calculate the number of subnets?
Total number of subnets: Using the subnet mask 255.255. 255.248, number value 248 ( indicates that 5 bits are used to identify the subnet. To find the total number of subnets available simply raise 2 to the power of 5 (2^5) and you will find that the result is 32 subnets.
What is the maximum number of subnets?
Maximum number of subnets = 2^6-2 =62. Note that 2 is subtracted from 2^6. The RFC 950 specification reserves the subnet values consisting of all zeros (see above) and all ones (broadcast), reducing the number of available subnets by two. Maximum number of hosts is 2^10-2 = 1022.
How many subnets are in a 24?
Class B
| Network Bits | Subnet Mask | Number of Subnets |
|---|---|---|
| /24 | 255.255.255.0 | 256 (254) |
| /25 | 255.255.255.128 | 512 (510) |
| /26 | 255.255.255.192 | 1024 (1022) |
| /27 | 255.255.255.224 | 2048 (2046) |
Why subnetting is required?
Subnetting ensures that traffic destined for a device within a subnet stays in that subnet, which reduces congestion. Through strategic placement of subnets, you can help reduce your network’s load and more efficiently route traffic.
What is subnetting explain?
Subnetting is the practice of dividing a network into two or more smaller networks. It increases routing efficiency, enhances the security of the network and reduces the size of the broadcast domain. Consider the following example: In the picture above we have one huge network: 10.0.
What is subnetting and its advantages?
Subnetting is the practice of dividing up a network into two or more networks. Common advantages of subnetting include enhancing routing efficiency, network management control, and improving network security.
How many types of subnets are there?
two types
What are the 3 classes of subnet mask?
The three default subnet masks are 255.0. 0.0 for Class A, 255.255. 0.0 for class B, and 255.255.
What is classless subnetting?
So, Classless Subnets means dividing already the Divided Classful Networks, and as mentioned, the Public IP Space initially was divided to 5 Classes, A, B, C, D, and E.
How do you implement subnetting?
Determine the number of subnets and hosts for each subnet required. The address class you are assigned and the number of subnets required determine the number of subnetting bits used. For example, with a Class C address and a need for 20 subnets, you will have a 29-bit mask (255.255. 255.248).
What is IP loopback address?
A loopback address is a special IP address, 127.0. 0.1, reserved by InterNIC for use in testing network cards. The loopback address allows for a reliable method of testing the functionality of an Ethernet card and its drivers and software without a physical network.
What are the 4 parts of an IP address?
IP Address Components
- Address Class. Early in the development of IP, the IANA (Internet Assigned Numbers Authority) designated five classes of IP address: A, B, C, D, and E.
- Default Subnet Mask.
- The Network Field.
- The Host Field.
- Non-default Masks.
- The Subnet Field.
How do I assign an IP address?
How do I set a static IP address in Windows?
- Click Start Menu > Control Panel > Network and Sharing Center or Network and Internet > Network and Sharing Center.
- Click Change adapter settings.
- Right-click on Wi-Fi or Local Area Connection.
- Click Properties.
- Select Internet Protocol Version 4 (TCP/IPv4).
- Click Properties.
- Select Use the following IP address.
Can I make my IP static?
You can assign these static IP addresses on the device itself—using, say, Windows’ network settings on each computer—or you can do it at the router level. Doing it at the router level is called assigning a DHCP reservation, though many people (and even some routers) still refer to it as a “static IP address.”
Do switch ports have IP addresses?
When computers are on the same IP segment, it means that the computers belong to the same network. But since the switch does not have the capability to assign IP addresses, the computers connected to it will not be able to communicate with each other. They will get an Automatic Private IP Address (APIPA).
How do I assign an IP address to a switch port?
Configure an IP address on a switch
- enter the VLAN 1 configuration mode with the interface vlan 1 global configuration command.
- assign an IP address with the ip address IP_ADDRESS SUBNET_MASK interface subcommand.
- enable the VLAN 1 interface with the no shutdown interface subcommand.
Does VLAN need IP address?
This IP address can only be used as the default gateway on a multilayer switch. A VLAN (Virtual Local Area Network) is its own logically segregated broadcast domain. You assign networks, or subnets, just as you would with a physically separated broadcast domain. VLANs do not really have IP addresses assigned to them.
How do I assign an IP address to a multilayer switch?
Step-by-Step Instructions
- Enable routing on the switch with the ip routing command.
- Make note of the VLANs that you want to route between.
- Use the show vlan command in order to verify that the VLANs exist in the VLAN database.
- Determine the IP addresses you want to assign to the VLAN interface on the switch.
What is the purpose of assigning an IP address to a switch?
What is the purpose of assigning an IP address to a switch? Explanation: Switch is a layer 2 device and doesn’t use network layer for packet forwarding. The IP address may be used only for administrative purposes such as Telnet access or for network management purposes.
