Script to find host names from list of IPs

[Azad]

I am looking for a script which can read a .txt file with a list of IP
addreses and fetch me the hostnames. Ideally the output format should be "IP:
xxx.xxx.xxx.xxx Host Name: ABCXXX". Could someone help me please?
I may not have admin access on some of the boxes, the script I am looking
for should work in these conditions as well. At the moment, I am using very
rudimentary method of writing a batch file with several entries of Ping -a
xxx.xxx.xxx.xxx >> output.txt which I have to massage it to get the desired
result.

You could do this with a simple batch file:
@echo off
for /F %%a in ('type d:\temp\IP.txt') do call :Sub %%a
goto :eof

:Sub
for /F %%b in ('nbtstat -A %1 ^| find "<00>" ^| find /i "unique"') do echo
%IP% Hostname: %%b

I get an error:

'Hosname' is not recognized as an internal or external command,
operable program or batch file.

Let's have a look at your batch file! Please mark clearly where
your lines start, e.g. like so:
Line1=@echo off
Line2=for /F %%a in ('type d:\temp\IP.txt') do call :Sub %%a
Line3=goto :eof

Thank you! That did fetch some results.

3 things that I noticed in the output:
1. IP address column is not seen in the output.
2. The Hostname shows <hostname>-W
3. I had about 150 IPs in the IP.txt file, the output had only 43 hostnames

Sorry, unless you post your version of the code I cannot
assist you.

As a further thought: You should also post the
output you get when executing this command
for an IP address that does NOT generate
the expected output:

nbtstat -A aaa.bbb.ccc.ddd

***Code***
@echo off
for /F %%a in ('type D:\test\IP.txt') do call :Sub %%a
goto :eof

:Sub
for /F %%b in ('nbtstat -A %1 ^| find "<00>" ^| find /i "unique"') do echo
%IP% Hostname %%b
***Command that I run***
D:\Test>pinglist >> output.txt
***Output***
Hostname 7996S1-W
Hostname 7920S1-W
***Output of nbtstat -A of missing info***
>nbtstat -A 10.9.160.40

Local Area Connection 4:
Node IpAddress: [172.17.224.83] Scope Id: []

Host not found.

I made a mistake in my script. It should read like so:
@echo off
for /F %%a in ('type D:\test\IP.txt') do call :Sub %%a
goto :eof

:Sub
for /F %%b in ('nbtstat -A %1 ^| find "<00>" ^| find /i "unique"') do echo
%1 Hostname %%b

About the command that fails to generate an output:
nbtstat -A 10.9.160.40
I cannot help you there. Either the machine 10.9.160.40
has some firewall restriction or there is something wrong
with its IP configuration. You can test the firewall part by
executing the command nbtstat -A 10.9.160.40 on the
machine itself.
