What is a 255.255 0.0 subnet?
What is a 255.255 0.0 subnet?
For example, as depicted in Table 4.9, 255.255. 0.0 is a standard Class B subnet mask, since the first two bytes are all ones (network) and the last two bytes are all zeros (host). Subnet masks are on a bit-by-bit basis; thus a subnet mask like 255.255. 240.0 (4 bits of subnet; 12 bits of host) can also be used.
Is 255.255 255.255 IP address valid?
255.255 represents the local broadcast address, which is only propagated within the network. This broadcast data cannot cross routers by default. For the local host, this address refers to all hosts in the network segment (same broadcast domain). Therefore, this address cannot be used for communication.
What is a 255.255 254.0 subnet?
255.255.254.0 = 23 bits mask = 510 hosts (512 -2 ) 255.255.252.0 = 22 bits mask = 1022 hosts (1024 -2 ) 255.255.248.0 = 21 bits mask = 2046 hosts (2048 -2) You always multiply by 2 or divide by 2..and remove 2 hosts (broadcast and network)
What destination adress is 255.255 255.255 for?
255.255. 255.255 is a special broadcast address, which means “this network”: it lets you send a broadcast packet to the network you’re connected to, without actually caring about its address; in this, is similar to 127.0. 0.1, which is a virtual address meaning “local host”.

What is 26 subnet mask?
The common subnet mask 255.255. A subnet mask of 255.255. 255.192 is 111. 000 in binary, or 26 ones, hence /26.

How do you subnet?
255.248 or /29.
- STEP 1: Convert to Binary.
- STEP 2: Calculate the Subnet Address. To calculate the IP Address Subnet you need to perform a bit-wise AND operation (1+1=1, 1+0 or 0+1 =0, 0+0=0) on the host IP address and subnet mask.
- STEP 3: Find Host Range.
- STEP 4: Calculate the Total Number of Subnets and Hosts Per Subnet.
What is a zero subnet?
Subnet Zero = Zero Subnet. If a network address is subnetted, the first subnet obtained after subnetting the network address is called subnet zero. Another definition: For every classful IPv4 network that is subnetted, the one subnet whose subnet number has all binary 0s in the subnet part of the number.
What should my subnet 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.
What is Subnet example?
An example of Class A IP address and subnet mask would be the Class A default submask of 255.0. 0.0 and an IP address of 10.20.
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 does 16 mean in IP address?
The `/16′ means that the first 16 binary digits is the network address, in other words, the `1.2. ‘ part is the the network (remember: each digit represents 8 binary digits). This means any IP address beginning with `1.2. ‘ is part of the network: `1.2. 3.4’ and `1.2.
What is your subnet mask?
To find the subnet mask of your Windows computer, go to the Run box (Windows Key + R) and cmd to open the Command Prompt. Here you can type the command “ipconfig /all” and hit the Enter key. The Subnet Mask will be listed as one of the parameters in the output under “Ethernet Adapters – Local Area Connection.”
