Can subnet mask be changed?

Do subnet masks have to be 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.

How do I find out what my DNS server is?

The easiest way to find out your dns server IP address is to go through the router’s admin interface status page. All routers have a built-in web-based setup page that allows the user to customize settings and set view properties such as IP address and dns settings.

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 …

How do you create a subnet?

What is IP address and subnet mask?

An IP address is an address used in order to uniquely identify a device on an IP network. The address is made up of 32 binary bits, which can be divisible into a network portion and host portion with the help of a subnet mask. The 32 binary bits are broken into four octets (1 octet = 8 bits).

How do I find my custom subnet mask?

What are the valid subnets?

Answer: The valid hosts are the numbers between the subnet number and the mask. For the 64 subnet, the valid host range is 64-126. For the 128 subnet, the valid host range is 129-190.

What is purpose of subnet mask?

A subnet mask is used to divide an IP address into two parts. One part identifies the host (computer), the other part identifies the network to which it belongs. To better understand how IP addresses and subnet masks work, look at an IP (Internet Protocol) address and see how it is organized.

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.

What is a subnet ID?

The second part of a TCP/IP address that defines the subnetwork in which the device resides. The subnet ID number is shared with the host ID. See subnet mask and subnet mask tables.

What is a LAN subnet?

A subnet represents all of the devices within a LAN, including all client, server, and host computers within that group. One benefit of creating a subnet is that it allows different computer groups to be connected to the Internet using a single shared public IP address.
