How do I find my subnet mask for Class B?
Example 6: The Class B 255.255. 255.128 subnet mask: 2-2=510 subnets.
…
…
- 2-2=14 subnets.
- 2-2=4094 hosts per subnet.
- 256-240=16.0, 32.0, 48.0, 64.0, etc.
- Broadcast for the 16.0 subnet is 31.255. Broadcast for the 32.0 subnet is 47.255, etc.
- The valid hosts are:
What is the default subnet mask of Class B?
255.255.0.0
Consequently, the default subnet mask for Class B is 255.255.0.0. In addition, Class C IP addresses are normally assigned to a very small-sized network. Their IP addresses range from 192 to 233 and their default subnet mask is 255.255.
What is a class B network?
A class B network is a type of network in the now-defunct classful networking architecture. … Class B networks have IP addresses between 128.0. 0.0 and 191.255. 255.255. The Classful networking system has been superseded by CIDR (Classless Inter-Domain Routing) since 1993.
What is subnet mask write default subnet mask for Class A Class B Class C?
The three default subnet masks are 255.0. 0.0 for Class A, 255.255. 0.0 for class B, and 255.255.255.0 for Class C.
Is 255.255 255.255 IP address valid?
In general, using 255.255. 255.255 is a bad idea, as there are several setups where the interface with the default route is exactly the wrong choice. Selecting an interface explicitly is better, but needs to be done carefully.
How many addresses are there in a class B subnet?
Class B Address
x.x. The default subnet mask for Class B is 255.255. x.x. Class B has 16384 (214) Network addresses and 65534 (216-2) Host addresses.
What is the subnet mask and describe the all class subnet mask?
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.
What are default subnet mask for each classes?
Default Subnet Mask
| IP Address Class | Default Subnet Mask |
|---|---|
| Class A | 255.0.0.0 |
| Class B | 255.255.0.0 |
| Class C | 255.255.255.0 |
What is the range of class B IP address?
Designing Your IP Addressing Scheme
| Class | Range | Network Address |
|---|---|---|
| A | 0-127 | xxx |
| B | 128-191 | xxx .xxx |
| C | 192-223 | xxx . xxx . xxx |
What is subnet mask on router?
A subnet mask is a number that defines a range of IP addresses available within a network. A single subnet mask limits the number of valid IPs for a specific network. … Systems within the same subnet can communicate directly with each other, while systems on different subnets must communicate through a router.
What is binary subnet mask?
A subnet mask, like an IP address, is 32 bits in length. … Subnet masks are composed of some number of 1 bits followed by enough 0 bits to form a 32-bit value. The bit positions with a 1 correspond with the bit positions in the IP address that are part of the network ID.
Which of the following is an example of a Class B IP address?
Class B Network
The first 16 bits (known as two octets) help you identify the network. The other remaining 16 bits indicate the host within the network. An example of Class B IP address is 168.212.226.204, where *168 212* identifies the network and *226.204* helps you identify the Hut network host.
What does a subnet mask of 255.255 255.0 mean?
A class C network would have a subnet mask of 255.255. 255.0 which means that 24 bits are used for the network. In CIDR notation this is designated by a /24 following the IP address.
What is my IP subnet mask?
On Android
Go to Settings > Wireless & Networks > Wi-Fi. Tap on the network you’re connected to. You will find the subnet mask along with other network details.
How is subnet mask calculated?
To calculate the subnet mask, convert an IP address to binary, perform the calculation and then convert back to the IPv4 decimal number representation known as a dotted quad. The same subnetting procedure works for IPv6 addresses. … This increases the number of subnetworks, while reducing the number of hosts per subnet.
Is 255.0 255.0 a valid subnet mask?
A subnet mask distinguishes the network identifier from the host identifier in an IP address, but is not restricted by the same rules as the class-based method. A subnet mask, like an IP address, is made up of four numbers. These numbers can range from 0 to 255. … 0.0 is a valid subnet mask as opposed to 255.0.
How many IPS does the subnet of 255.255 255.0 have?

What is subnet number?
A subnet number is a specific part of a subnet address in an IP address that identifies one among several subnets as the recipient or originator of a data packet. The subnet number helps browsers to accurately use the Internet to deliver messages to specific parts of a party’s full network.
