I have a large list of IP addresses from a database that I need to sanitize and determine which type of host (it'll be one of 2 device types) each IP address relates to.
Is there a way of using a batch file and/or Putty to telnet to (but not necessarily log in to) each host, check the initial message from the host, log it to a file and then disconnect and test the next one and so on?

I you do know how-to achieve your task for a particular (hard-coded) IP address, then yes, it's possible using modified loop:
FOR /F "delims=" %%G IN (list_of_IP_addresses.txt) DO ECHO %%G– JosefZ – 2015-06-23T22:24:37.913
