On Windows, how to determine route for IP destination?

Question

How can I determine the IP route taken for a specific IP destination (without looking at "route print" and figuring it out manually)?

In OS X there's route get 1.2.34 and in Linux there's /sbin/ip route get 1.2.3.4. Is there anything like that on Windows?

Solution 1

Yep. Open a command line and type tracert 1.2.3.4

Solution 2

In Powershell:

Find-NetRoute -RemoteIPAddress "10.0.0.34" | Select-Object ifIndex,InterfaceAlias,DestinationPrefix,NextHop,RouteMetric -Last 1

ifIndex           : 10
InterfaceAlias    : Ethernet 2
DestinationPrefix : 10.64.0.0/10
NextHop           : 0.0.0.0
RouteMetric       : 0

Solution 3

The pathping command is similar to tracert but includes the outgoing interface.

Using cygwin, this command gives the outgoing IP/interface for a particular destination (specified by $HOST):

pathping -n -w 1 -h 1 -q 1 $HOST | head -n 4 | tail -n 1 | awk '{print $2}'

if you are willing to use Powershell you can use the Get-NetRoute cmdlet, technet.microsoft.com/en-us/library/hh826126.aspx

Heh, good point. Not an optimal solution, since it does query the network for something you know locally, but for the most part, gives me the information I need.

@Ilya: Using -d (no resolve IP) and -w 0 (don't wait for ping) should speed up the scan a lot.

This doesn't really do the same thing. The route get commands the original posted mentions perform a lookup in the local routing table and return the result. For example, you can ask ip route get 192.168.1.32/28 to find which routing table entry will be used for that network, but you can't ask tracert about network blocks.

@Hello71 -w 0 is not working in my case (gives error Bad value for option -w.). -w 1 works however.

This is not the correct answer. tracert doesn't give the routing information such as which interface is being used.

This is a better answer. pathping -n -w 1 -h 1 -q 1 $HOST was also very informative for me. Helped me figure out a problem I was having.

tbh this should be upvoted more. Find-NetRoute is probably the closest you're going to get to ip route get on Windows.

Note that this will not work on Windows 7 (and lower). Should work on Windows 8 (and above).

This should be the accepted answer. Btw, powershell seems not designed for daily interactive use ...
