Can you ping a subnet mask?

It does, however, have another way to do a broadcast ping: just send a normal ping to a special IP address on your network. If my subnet mask were 255.255. 0.0 , then the ping address would be 192.168. $ ping 192.168.

How do I find my subnet mask on another computer?

With some trial and error, you can use “tracert” from the command line to ping neighboring IP addresses to see where the route ends up. That is, assuming there’s no firewall blocking ICMP requests. If the second-to-last IP stays the same, you’re in the subnet.

How do I create a subnet mask?

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.

Is 255.255 255.255 IP address valid?

No, it is not possible to have any source 255.255. 255.255 as IP Address because this IP Address is already reserved for the broadcast address.

What is subnet mask in Linux?

The subnet mask of an IP address is what tells the computer or router or whatever which part of your IP address belongs to your network and which part belongs to the hosts.

What is the default subnet mask for Class C IP address?

By default, the subnet mask for a Class C IP address class is set to 255.255.255.0, meaning that the first 3 octets (24 bits) in an IP address are used to identify the network ID, and the last octet (8 bits) are dedicated to the host ID.

What does a host’s subnet mask tell a router?

READ:   Which is the best picture of Amitabh Bachchan?

A host’s subnet mask does not as such tell a router anything. Instead, the subnet mask is used to determine whether a destination IP address is on the local subnet or whether it is in some remote subnet and has to be sent to the router for onward destination. That determination occurs on the host.

What is an IPv4 subnet mask and how to calculate it?

The subnet mask tells a router which bits to pay attention to when calculating the network ID portion of an IP address. You can calculate IPv4 subnet masks by hand if you so desire, but it is much easier to just use a subnet calculator. For the die hard, however, let’s walk you through IP subnetting step by step.

How many subnet bits do I need for my subnet mask?

1. Since we need only two subnets, we need 21 subnet bits. In our case, this means that we will take one bit from the host part. Here is the calculation: First, we have a class C address 192.168.0.0 with the subnet mask of 24. Let’s convert them to binary: We need to take a single zero from the host part of the subnet mask.
