Python program to find IP Address
Sounds simple enough. However, as with many tasks in the world of PowerShell, there are several ways to get the job done. Some of the techniques will require that you have administrator privileges on the remote computer. Some will be firewall friendly and some not. You can decide which approach works for you. Another advantage is that it makes it easier to turn your test code into a PowerShell function. The first technique is to use the Test-Connection cmdlet.
This is a PowerShell version of ping. By default, the cmdlet pings four times, and you can see there is an IPv4 address. To simplify, I will select only the information I care about and limit test to a single ping.

The actual property name, which you can find with Get-Member is Address. Renaming the Address heading. Another approach is to use WMI. The syntax is essentially the same. And since it was there, I decided to grab the MAC address as well. These cmdlets were packaged as modules and were much easier to use than trying to query WMI directly. The cmdlet requires that the target computer be running at least PowerShell 3. Or you can use a CIM Session object you defined separately. All I have to do is tell PowerShell to replace them.
This module includes cmdlets for resolving host names from DNS. This code will now include a new property indicating if the computer is responding to pings. You could speed this up a bit by limiting the ping count in Test-Connection.

You have to decide if you want something that works for you or something that can be shared. Every system has multiple IPs. A portable solution answers the Q: "what IP do I use to reach blah? I added an additional grep to your code to ignore any interface with "eth0:" in it; this now works as I expect giving only the "eth0" IP address and not any sub-interfaces eth, eth, etc. Chris F Carroll 4 4 bronze badges.

Oh goodness, thank you for this answer.
Never heard of moreutils before. I was seriously considering writing my own little C program to do exactly that. It would be nice to have ifdata added into iproute2. Mikel Mikel This has to be the best answer because 1 it doesn't assumes a device name, 2 it uses 'ip' as opposed to old school 'ifconfig', and 3 it supports ipv6 as well. I agreed, it the best start for most use cases. You can also easily get other interface parameters. S Oct 17 '17 at If grep isn't enough, don't pipe it to something else.
Just use the something else sed , awk , etc. The short answer is: ip route get 8. Using awk ip route get 8.
