If It's important for you have ever had to go to your router, you should know the internal IP address. Its what you type in of your default gateway, which is normally your browser to reach it (ie http://192router's LAN IP address.168.1.1/) and, if not, you can find it with the following steps:

If you have ever had to access your router to configure it, you should know the address. It's what you type in your browser address bar to reach the configuration interface (example: http://192.168.1.1/) and, if not, you can find it with the following steps: * <b><u>If Windows OS</u>:</b><br /><br />

** When Command Prompt is open, type the following command: <code>ipconfig| findstr /i "Gateway"</code>(You can copy & paste it in the command prompt; just right-click anywhere in the command prompt window and select ''Paste''.)<br /><br />** You should see something like this:  <br /><code>C:\UsersDocuments and Settings\Usernameadministrator>ipconfig  Windows IP Configuration   LAN adapter Network Connection:  Connection-specific DNS Suffix . : Link-local IPv6 Address . . . . . : fe88::7d0d:8844:62d7:3155%10 IPv4 Address. . | findstr /i "Gateway"<br /> Default Gateway . . . . . . . . . : 192.168.1.2221</code><br /><br /> Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : ** In this example, your default gateway (router) IP address is <b>192.168.1.1</b>.

* <b><u>If Linux OS</u>:</b><br /><br />** You'll need to open a Terminal. Depending on your Linux distrobutiondistribution, it can be located in the menu items at the top, in or at the bottom of your screen. In this example, we will use Fedora. Click <b>Applications</b> > <b>System Tools</b> > <b>Terminal</b>.<br /><br />

** The output of this should look something like the following:  <br /><code>joe$ ip route | grep default<br />default via 192.168.1.1 dev eth0 proto static</code><br /><br />** In this example, again, <b>192.168.1.1</b> is your default gateway (router) IP address.

* <b><u>If Mac OSX</u>:</b><br /><br />** In Mac OS you will need to open up terminal as wellOpen the Terminal application. Do do this, click <b>Finder</b> > <b>Applications</b> > <b>Utilities</b> > <b>Terminal.app</b>.<br /><br />** When Terminal.app is open, type the following command: <code>ipconfig getpacket en1netstat -nr | grep default</code><br /><br />Where <b>en1** This will output the following:<br /b> is the adapter you are connected to, the default for wire (ethernet) is <bcode>eth0</b>, in my case, im connected through wireless adapter, so the joe$ netstat -nr | grep default on my MacBook is en1 (late 2008 model).<br /><br />** This will output the following:  op = BOOTREPLY htype = 1 flags = 0 hlen = 6 hops = 0 xid = xxxxxxxxx secs = 0 ciaddr = 0.0.0.0 yiaddr = default 192.168.1.x siaddr = 0.0.0.0 giaddr = 0.0.0.0 chaddr = 0:00:0:0x:00:0x sname = file = options: Options count is 7 dhcp_message_type (uint8): ACK 0x5 server_identifier (ip): 192.168.1.1 lease_time (uint32): 0x15180 subnet_mask (ip): 255.255.255.0 router (ip_mult): {192.168.1.1} domain_name_server (ip_mult): {192.168.1.1} end (none):[UGSc 50 46 en1</code] In this output, the part that shows ><codebr />router (ip_mult): {192.168.1.1}<br /code> where ** In this example, again, <b>192.168.1.1</b> is the your default gateway (router ) IP or gateway IPaddress.
