Use this option to see the full list of Ping options and usage syntax. Good for finding out how many packets your routers can quickly handle, which is in turn good for diagnosing problems that only appear with large TCP window sizes. Send preload packets as fast as possible, then fall into a normal mode of behavior. This used to stress test the performance of a network and should be avoided. Display additional ICMP packets that provide very detailed information.
Check very large packets that must be fragmented. This only works for hosts that can be directly reached without using any routers. Use this when you suspect routing problems and ping can't find a route to the target host.
Target host may not provide the information.
If a fault indicator is on, follow the cable from your PC to the router to make sure it is properly connected, then call your cable or broadband provider if necessary. Check that the router has the proper indicators light (and no faults), including the one that indicates a good connection to your PC.As the ping command transmits packets at about 1 per second, you should be able to see the data light blink. Most PC network ports have an indicator light that indicates a good connection and one that blinks as data is transferred.The next column in the output is headed Physical Address. The output shows all of the IP addresses that are active on your network. Open a Command Prompt window and enter the command arp -a. Check your wireless connection or the connection from your PC to your router, especially if it was working previously. Can you find an IP address from a MAC address Yes.If this fails, your TCP/IP is not functioning correctly, and your network adapter needs to be reconfigured. Sendto: No route to hostThis may mean the address of the gateway is incorrect or that the connection from your PC is not up and running. Your IP address will appear in the right pane of the window.Check your connection. In the Network window, select the network adapter you are interested in. In the System Preferences menu, select Network.
Click the Apple menu in the upper left corner of the screen.Ģ. This line displays the Active Directory MAC address, which will take the form of a string of characters and numbers, separated by dashes. To find the computer’s MAC address, look at the ‘Physical Address’ section.
This line will display the IP address for your system Usually the serial number is used to display the IP address of the form 192.168.1.1.ĥ. To find the computer’s IP address, search for ‘IPv4 Address’ or ‘IP Address’. For example, you can find network information for wireless adapters by looking at the ‘Ethernet Adapter Wireless Network Connection’ section.Ĥ. You can search for information about the adapter connected to the network. The command prompt window will give you information about the network adapter in the computer.
