Match ip to hostname

[spanga]

Matching IP-adresses could be done by using Windows Ping command with the -a flag. But is there a better/faster way? I need to match 500 IP-adresses in my script so I guess the "Ping -a" method would be kinda slow. Anyone know of a better way to do this?

Got this now:

#include <Constants.au3>
$IP = "64.111.104.70"
$HostNameString = Run(@ComSpec & " /c ping -a -n 1 -w 1 " & $IP, @SystemDir, @SW_HIDE, $STDERR_CHILD + $STDOUT_CHILD)
$HostName = StringSplit(StringTrimLeft(StdoutRead($HostNameString),25)," ")
$HostName = $HostName[1]

Allthough I'm still interested in a workaround the Run-function, as me nor some AV's dislike programs executing other programs.

For hostname to IP you can use TCPNameToIp from the beta (http://www.autoitscript.com/autoit3/files/beta/autoit/)

But IP to Hostname? I will try to write a script for it but its not so easy... So i don't know if i can get it done.

DOS has a nice DNS<->IP command, commonly known as 'nslookup'

Just do a string manipulation with that, and viola

also, autoit has its own ping command.. so you don't need to do a run at all.

won't return the hostname tho.

Try this...

If you have all 500 IP Addresses listed on a single line in a text file you could use FileReadLine(), pass it to the MS_DOS Ping command, and create a new text file with IP Address and the corresponding Hostname on each line.

To decrease the time it takes MS_DOS Ping to return info add the "-n 1" switch to ping destination only once.

I use such a script at work against thousands of workstations...takes about 2 - 3 minutes depending on network bandwidth.

Make sure you add a feature for skipping over workstations that are offline.

I put this in Scripts & Scraps...

I.P. <> HostName
