Find All IPs with a specific hop in the trace
Hi Experts..
I need a PowerShell script to Tracert an entire range (For Example 10.20.30.[0-255])
And search for a specific Address as one of the hops (For example 10.56.44.12)
and if that address appears, that address will be appended to a simple text file.
Any ideas?

Is ICMP enabled?
If so, you could start with tracert -d (no DNS resolution).
I just want to make sure ICMP is not disabled before I suggest next steps for Powershell.
Apologies.

The computer that will be running the script is open with DMZ to the entire range, and ICMP is certainly enabled on both the sources (10.20.30.0-255) and the Destination 10.56.44.12 (These are example addresses)
There might be addresses in the path that won't answer though.
Also, if it's relevant, we can't assume the required IP Address will always be the same hop.

What are we working with?
.NET 4.5.2 with MS Management Framework 4.0 aka Powershell 4 is good.
.NET 4.6 with MS Management Framework 5.0 aka Powershell 5 with DSC better
Either works, which one?

So that I'm clear, all you want to do is pass a variable to a range or array of IP?
So, mytrace 10.56.44.12
And output all the "hops" to get at that IP?
Is it one subnet? There are no hops, yes? I'm missing something. It happens.

Well, someone beat me to it. If this works, we should not make a new wheel. I'm not convinced yet it will do what you want, however. Because I'm not sure what that is, yet.

They probably used Sapien Powershell Studio. That is what I used, they compiled a binary script that pings but also gives TTL.
Ping Admin tool is powerful tool based on PowerShell scripting.
Using Power Admin tool you can Ping to Single, multiple Server/computers or IP range.
Moreover, Ping Admin tool gives you OS type as well in the output, along with FQDN and IP address.
If, IP range selected then it will show TTL value as well.

That works, but there are some awesome new SDK's for WMF 5.0
I could not get that ping tool to run

Still, what is the output look like in your dimension? Take out the text file for a moment....
Here is a very basic port scan, 1 liner. But you said something about finding a specific IP in a subnet or subnets? What is the deliverable here?
IPAddress HostName Ports
--------- -------- -----
10.0.0.2 DC01.hacme.local {53, 139, 389, 445...}
10.0.0.3 SRV01.hacme.local {21, 80, 139, 445...}
10.0.0.10 SP01.hacme.local {80, 139, 445}

The # of IP's changes the design. Look at Test-Connection and the difference between async and sync scans.

I may have not explained myself properly.
I have a certain range 10.20.30.0\24
I need to use the command tracert -d for each and every address in the range,
Then to scan the output for a certain hop (10.56.44.12 for example) and then to write to a file only those addresses which have that speific address in the trace.
(To make it simpler to understand the point of the exercise, I have two firewalls, both sitting behind Junipers, Some addresses are routed to the old firewall and some to the new. I need to those which are routed to the old one to know which ones I have to migrate. Since the person managing the Juniper Routers is out of the country for the next couple of months, I'll have to do it this way as I have no CLI access to the Juniper router)

So, NMAP
https://nmap.org/
Does all that and more, you just populate your text file with your ranges or CSV and it will export everything out to whatever you want; txt, csv, html.
I run it on Linux and Windows. I have on my MGMT server in the DMZ. Along with a bunch of other cool stuff.
I mean, I'm willing to play but what your asking is not something I can pull off in a day. But I'll help if NMAP is not an option for you.

Actually, David. I forgot about hdping.
It is still supported.
And free, http://www.hping.org/

But, not sure it will do "exactly" what you want so I'll start looking at Powershell options. I have a few ideas.

Use this for a start:
Dan
$ipClass = "10.20.30."
$ipStart = 1
$ipEnd = 254
$resultsFile = "X:\your\results\file.txt"
for ($i = $ipStart; $i -le $ipEnd; $i++) {
$ip = $ipClass + [string] $i
$traceResult = Test-NetConnection $ip -traceroute
if ($traceResult.TraceRoute -like "*10.56.44.12*") {echo $ip >> $resultsFile}
}
