need http request help

[idiot]

ok i need to try and open ip adress's with range 192.168.*.*
and test to see if each one is working or not and for it to either log results to file or just inform me as it finds working ones
is there a simple way to do this?

I guess you need two nested loops of 255 iterations each:

Code: Select all

Let>quad3=0
Repeat>quad3
  Let>quad3=quad3+1
  Let>quad4=0
  Repeat>quad4
    Let>quad4=quad4+1
    
    Let>IP=192.168.%quad3%.%quad4%
    //HTTPRequest>.......
    
  Until>quad4=255
  
Until>quad3=255

But I should think this will take a very long time as you are attempting 255*255 = 65025 http requests!! What you might want to do is perform a ping first to see if the IP address responds before attempting to do a HTTPRequest. Even so I think this is going to be very slow .....

A few FWIW comments:

As Marcus writes this will be very slow since (I'm guessing) you'll be waiting for timeout on most of the IP range.

HTTP Request may not tell you what you want to know unless you are looking for a webserver.

If you are looking for the IP of some device that you know is on the network but have lost track of the address then (if it's a small network) I would first use Microsoft's free Network Monitor and look for traffic from unexpected IP's. Note that the output can be overwhelming without using the filtering options.

If that doesn't work I would use a tool like nmap which can scan the network using ping and other protocols (important because not everything returns a ping). Note nmap and similar programs can be regarded as hacker tools so be careful only to use them where you are authorized to do so (also some of the websites offering downloads of such programs may be nasty).

appreciate it both of you thanks
