Ipconfig / displaydns : It shows the local DNS resolver cache entries as explained above. This command is useful when troubleshooting DNS connection problems. This cache stores DNS entries of frequently accessed internet resources so that the computer will not query an external DNS server every time you try to access an internet resource (website etc). Ipconfig /flushdns : This deletes the local DNS resolver cache of the computer. Ipconfig /renew6 : Same as above but for the IPv6 address. Ipconfig /renew : This usually comes after the above command and is used to request a new IP address from a DHCP server. Ipconfig /release6 : Same as above but for the IPv6 address. If you specify also a connection name at the end, it will release only the IP of that connection adapter. Ipconfig /release : This will release the current IPv4 addresses which were assigned dynamically from a DHCP server. Ipconfig /all : This will display output as shown on the screenshot above but for ALL network connection adapters of the computer (Wired Ethernet, WiFi, Vmware adapters etc). Ipconfig /? : Displays all available options. Here are some different options of this command:

Here is a screenshot example of what you can expect as output from ipconfig:Īs shown above, you get information such as IPv4 and IPv6 address, MAC address, Default Dateway, DNS Servers etc. If you want to find the local IP address assigned to your computer or the MAC address of your Ethernet Adapter (shown as “ Physical Address” in the command output as shown in the picture below), this is the quickest way to find this information. It displays tons of useful information about the current network settings on the machine such as IPv4 and IPv6 address of all network interface cards (Ethernet adapters, WiFi adapters, virtual network adapters etc), MAC address, default gateway, subnet mask, DNS server, DHCP information etc. This is one of the most useful IP commands on Windows.

Having knowledge of the following IP commands will add a strong array of resources in your troubleshooting arsenal.Īt the end of this post you will find a download link for the PDF version of this article with all the commands which you can download for your own use. I have found myself thousands of times to start troubleshooting network and connectivity problems from an end-point device first (computer, server etc) before moving on to the actual core network devices for further investigation. Most of these commands (with some exceptions and variations) are also available on Linux OS. In this article we’ll list and describe the most useful and helpful IP Commands on Windows operating system. In addition to having strong knowledge of networking protocols and commands on network devices (routers, switches, firewalls etc) we need also to have very good knowledge of IP and other networking related commands on end-point devices such as Windows computers, Linux servers and workstations etc. As Network Engineers we need to be versatile and troubleshooting-savvy in our work environment.
