What is the correct subnet mask?

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. 255.192, which limits the number of IP addresses to 64. Large networks with several thousand machines may use a subnet mask of 255.255.

What is subnet mask 23?

Class A

/21 255.255.248.0 2046
/22 255.255.252.0 1022
/23 255.255.254.0 510
/24 255.255.255.0 254

Why do we need a subnet mask?

– A subnet mask allows identification of host part and network part of an IP address. – Subnet mask can be used to find if an IP address is present on a subnet or not. – It is a 32-bit number which masks an IP address and divides it into network and host address. …

How to calculate subnet mask and IP address?

So any octet that’s 255 is just 11111111 in binary. This means that 255.255.255.0 is really 11111111.11111111.11111111.00000000 in binary. Now let’s look at a subnet mask and IP address together and calculate which parts of the IP address are the network bits and host bits.

Which is the subnet mask of 192.168.0.101?

Another way to express this is with a network ID, which is just the network portion of the IP address. So the network ID of the address 192.168.0.101 with a subnet mask of 255.255.255.0 is 192.168.0.0. And it’s the same for the other devices on the local network (192.168.0.102, 192.168.0.103, and so on).

How to calculate CIDR noation for a subnet mask?

How to Calculate CIDR Noation. To figure out the CIDR notation for a given subnet mask, all you need to do is convert the subnet mask into binary, then count the number of ones or “on” digits. For example:

How many IP addresses in a Class B subnet?

Class B IP addresses range from 128.0.0.0 to 191.255.255.255, with a default subnet mask of 255.255.0.0 (or /16 in CIDR). Class B addressing can have 16,384 (2 14 ) network addresses and 65,534 (2 16 ) usable addresses per network.

So any octet that’s 255 is just 11111111 in binary. This means that 255.255.255.0 is really 11111111.11111111.11111111.00000000 in binary. Now let’s look at a subnet mask and IP address together and calculate which parts of the IP address are the network bits and host bits.

What is the default mask for Class A IP addresses?

Class A IP Addresses For Class A IP addresses, the first octet (8 bits / 1 byte) represent the network ID, and the remaining three octets (24 bits / 3 bytes) are the host ID. Class A IP addresses range from 1.0.0.0 to 127.255.255.255, with a default mask of 255.0.0.0 (or /8 in CIDR).
