Question: What Is The Default Subnet Mask?

Is subnet mask always 255?

Again a basic example of a subnet mask uses only the numbers 255 and 0 numbering octets; therefore, to identify the network, any part of the address matched up with a 255 is not changed at all, so the first three octets of the IP address (69, 163, 177) will all be matched with 255 allowing the original numbers to be ….

Is default gateway same as router?

A gateway and a router are essentially the same. The term “default gateway” is used to mean the router on your LAN which has the responsibility of being the first point of contact for traffic to computers outside the LAN.

Is default gateway same as IP address?

A default gateway is an IP address that is specified in a device to enable it to communicate with other devices that are not in the same network. Normally it is an address of the router interface that is connected to a network. The default gateway is always same as the IP address, the last byte or number is changed.

What is Subnet Mask example?

Subnet masks are also expressed in dot-decimal notation like an address. For example, 255.255. 255.0 is the subnet mask for the prefix 198.51. 100.0/24.

How do I find the default subnet mask?

Since classes A, B and C divide the network ID from the host ID on octet boundaries, the subnet mask will always have all ones or all zeroes in an octet. Therefore, the default subnet masks will always have 255s or 0s when expressed in decimal notation.

What is a default gateway and subnet mask?

A gateway IP refers to a device on a network which sends local network traffic to other networks. The subnet mask number helps to define the relationship between the host (computers, routers, switches, etc.) and the rest of the network.

What is the subnet mask for?

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.

What is the default subnet mask for a class B network?

255.255.0.0Class B networks use a default subnet mask of 255.255. 0.0 and have 128-191 as their first octet. The address 172.16. 52.63 is a class B address.

What are the 4 parts of an IP address?

IP Address ComponentsAddress Class. Early in the development of IP, the IANA (Internet Assigned Numbers Authority) designated five classes of IP address: A, B, C, D, and E. … Default Subnet Mask. … The Network Field. … The Host Field. … Non-default Masks. … The Subnet Field.

What’s the subnet mask of my router?

The most simple way to find your own subnet mask is to run a simple command line in windows. Simply press the Windows key and “R” at the same time to open the command prompt and type “cmd” followed by “enter.” This will allow you to see your subnet mask (as shown below!). It’s as simple as that!

What is the difference between default mask and subnet mask?

NOTE: All Class C Classful IP Addresses have a 24 bit subnet mask (255.255. 255.0). … On the other hand, the use of an IP Address with a subnet mask other than the default results in the standard Host bits (the Bits used to indentify the HOST ID) being divided in to two parts: a Subnet ID and Host ID.

What is the use of a default gateway?

The default gateway is the path used to pass information when the device doesn’t know where the destination is. More directly, a default gateway is a router that connects your host to remote network segments. It’s the exit point for all the packets in your network that have destinations outside your network.
