How to find Subnet Mask

How to find Subnet Mask

If you want to find your subnet mask of the network or if you are in the network but want to know what is my subnet mask, here is a handy article for you. Subnet mask helps to identify which section of an IP address is reserved for network and which part is available for the use of host. Subnet mask is also known as netmask. Now I’m going to tell you how to find subnet mask on your local network.

Windows Vista/ XP/NT/2003 – On Windows Vista, XP or other NT versions you can follow simple steps below.

[1] Go to Start Menu -> Run

[2] Type “cmd” and press enter to open the command prompt window.

[3] Now type “ipconfig /all” [without quotes]

You will get the subnet mask on your local network like the following screenshot.

Also you get the same information from the properties of Local Area Network. Just go to Start Menu -> Settings -> Network Connections and double click the Local Area Network icon. Then just click on the support tab at the top of the window.

Linux/ Unix – On Linux or Unix system just type following commands on shell to get the subnet mask.

$ ifconfig

or

$ /sbin/ifconfig

or

$ /sbin/ifconfig interface-name

The output will be as follows…

lnc0: flags=108843 mtu 1500

inet 72.122.61.51 netmask 0xfffffff8 broadcast 72.122.61.55

ether 00:0c:29:32:8a:8c

plip0: flags=108810 mtu 1500

lo0: flags=8049 mtu 16384

inet6 fe80::1%lo0 prefixlen 64 scopeid 0×3

inet6 ::1 prefixlen 128

inet 127.0.0.1 netmask 0xff000000

The netmask is the subnet mask and displayed in hexadecimal format.

Know WhoIS info of site with DOS prompt

Know WhoIS info of site with DOS prompt

Here I’m going to tell you one very interesting way to get WhoIS information of any domain or IP address from your desktop. Yes, mostly or say almost all time we need to depend on different WhoIS websites. But, you can easily get all WhoIS information directly from DOS Command Prompt just by typing “whois www.domain.com” [without quote]. You will get the output on your DOS screen like this…

In Linux Shell you can direct get WhoIS information, but to obtain it from DOS you need to install a small EXE from Microsoft’s TechNet Webstie. You can download this EXE from here. After downloading, extract the EXE file to your System folder. [e.g. \Windows \ System32 or WinNT \ System32. If you are using Windows98 then \Windows\ System ]. That’s all, now simply type whois followed by any domain name or IP address on your command prompt and get all details. But, obviously this command will only work when you are connected with Internet.
