Use the 'ifconfig' command on your adaptor, or just 'ifconfig -a'
Google it.
You can't find the gateway or any other address in a subnet mask; the subnet mask is used to separate the parts of an address - the network id part and the host id part. Look at other settings for the gateway, such as ipconfig or ifconfig
Get Subnet Mask, IP Address, Gateway etc.For windows users go to START button in bottom left corner then to RUN then type COMMAND in the box - the mini DOS prompt will open in a separate window. Then type ipconfig/all and all the information you desire will be listed - ip address, default gateway, subnet mask etc.......
To find the IP address, subnet mask, default gateway, and DHCP server on a Windows computer, you can use the command ipconfig /all in the Command Prompt. This command provides detailed information about all network interfaces, including their IP configurations. On a Linux or macOS system, you can use the command ifconfig or ip addr show to find similar network configuration details.
On Windows systems:Click Start > Run. Then type: cmdThe 'DOS' box will open, type: ipconfig /all(Note: there is a SPACE after the word ipconfig) The information displayed will be similar to the below if you have a single address;C:\Documents and Settings\xxxx>ipconfig /allWindows IP ConfigurationHost Name . . . . . . . . . . . . : machinePrimary Dns Suffix . . . . . . . :Node Type . . . . . . . . . . . . : UnknownIP Routing Enabled. . . . . . . . : NoWINS Proxy Enabled. . . . . . . . : NoDNS Suffix Search List. . . . . . : hsd1.ma.comcast.net.Ethernet adapter Local Area Connection:Connection-specific DNS Suffix . : hsd1.ma.comcast.net.Description . . . . . . . . . . . : 3Com EtherLink XL 10/100 PCI TX NIC (3C905B-TX)Physical Address . . . . . . : 00-10-5A-13-53-F7Dhcp Enabled. . . . . . . . . :YesAutoconfiguration Enabled. . . :YesIP Address. . . . . . . . . . . . : 65.12.23.123Subnet Mask. . . . . . . . . . . : 255.255.248.0Default Gateway. . . . . . . . : 66.31.48.1DHCP Server. . . . . . . . . . : 68.87.71.8DNS Servers . . . . . . . . . . . : 68.87.71.22668.87.73.24268.87.64.146Lease Obtained: Friday, April 17, 2009 12:34:21 PMLease Expires: Tuesday, April 21, 2009 12:34:21 PMNote: Type the word: exit > then hit the Enterkey to close the DOS session.On Mac or Linux/Unix systems:Launch the Terminal located in /Applications/Utilities/Type the following command:ifconfigYou will see most of the same info as the Windows example above. Your IP, subnet mask and gateway will all be clearly marked.
To find the subnet address, perform a bitwise AND operation between the destination address (198.47.34.31) and the subnet mask (255.255.244.0). In binary, the destination address is 11000110.00101111.00100010.00011111 and the subnet mask is 11111111.11111111.11110100.00000000. Performing the AND operation results in the subnet address of 198.47.32.0.
To find the gateway address in a router-based network, you can check the network settings on your device. On Windows, open Command Prompt and type ipconfig, then look for the "Default Gateway" under your active network connection. On macOS or Linux, open a terminal and type ip route or netstat -rn, and the gateway will be listed as the default route. Alternatively, you can log into the router's web interface using its IP address, typically 192.168.1.1 or 192.168.0.1, and find the gateway information there.
The gateway address is your router's inside local address. To find what your gateway and IP are you can open a Command Prompt (CMD) window and type "ipconfig/all" without quotes. Make sure you run the Command Prompt as an administrator when you open it.
To find a subnet on a Windows machine, open the Command Prompt by typing "cmd" in the search bar and pressing Enter. Then, type the command ipconfig and press Enter. Look for the "IPv4 Address" and "Subnet Mask" under your active network connection; the subnet can be derived from these two values. For example, if your IPv4 Address is 192.168.1.10 and the Subnet Mask is 255.255.255.0, your subnet is 192.168.1.0/24.
To find the network broadcast address for the IP address 216.14.55.137, you need to know its subnet mask. Assuming a common subnet mask of 255.255.255.0 (or /24), the network address would be 216.14.55.0, and the broadcast address would be 216.14.55.255. Therefore, if using a /24 subnet, the broadcast address for 216.14.55.137 is 216.14.55.255. If a different subnet mask is used, the broadcast address would change accordingly.
Question is too vague, do you mean, How do you find a subnet on a windows machine? How do you find a subnet on a Linux machine? How do you find a subnet owned by the service provider??
To find your subnet mask and gateway you will need to open a command prompt as administrator. In the command prompt type "ipconfig/all" without the quotes. It will then display all of your network information alone with those IPs.
