What is the difference between subnet mask and default subnet mask?

A subnet mask is a four-octet number used to identify the network ID portion of a 32-bit IP address. A default subnet mask is based on the IP address classes we discussed earlier and is used on networks that are not subdivided.

What is a default Subnetmask?

Most home networks use the default subnet mask of 255.255. 255.0. This is the default subnet mask used by Class B networks and provides up to 65,536 IP addresses (256 x 256). The largest Class A networks use a subnet mask of 255.0. 0.0, allowing for up to 16,777,216 IP addresses (256 x 256 x 256).

How do the subnet mask and Supemet mask differ from a default mask in Classful addressing explain with an example?

A subnet mask has more consecutive 1s than the corresponding default mask. A supernet mask has less consecutive 1s than the corresponding default mask. A subnet mask is used to identify which parts of the ip address are the network parts and which parts are the host parts.

Are all subnet masks the same?

Subnet masks always work from left to right. Devices are said to be within the same subnet if their IP Address starts with the same digits, but ends with a different set of digits. If the subnet mask is 255.255. 255.0, then the first three octets of all devices must be the same.

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 the default subnet mask for apipa?

The IP address range for APIPA is (169.254. 0.1 to 169.254. 255.254) having 65, 534 usable IP addresses, with the subnet mask of 255.255. 0.0.

What is default mask in ipv4 addressing?

Solution : The default mask is 255.255. 0.0, which means that the only the first 2 bytes are preserved and the other 2 bytes are set to 0. Therefore, the network address is 132.6.

What do you mean by sub netting and super netting explain it with example?

Subnetting is the procedure to divide the network into sub-networks or small networks. Supernetting: Supernetting is the procedure to combine the small networks into larger space. In subnetting, Network addresses’s bits are increased. on the other hand, in supernetting, Host addresses’s bits are increased.

Can 2 different subnet masks communicate?

If two computers are on different networks, they have a different subnet mask and they can’t communicate to each other, unless connected by a router.

What happens if subnet mask is wrong?

If the netmask is wrong, the program tries to directly access sites where it has to go through the router, or vice versa. The netmask defines, which part of the IP-address is used as address for the network and which part is used for the workstations. Both IPs are in the same net.
