Ex4:    atsn /if ipaddresses.txt      Read ipaddresses.txt for IPs to resolve General Note:    It should be obvious but the output format is...    IPADDRESS ; SITE NAME ; SUBNET NAME    Assuming a valid IP address, there should always be a site name    but subnet name will only be filled if there is a specific subnet    that the IP address maps to. So if you have a subnet that doesn't    map to any specific subnet, it will still be considered part of    some site. This software is Freeware. Use it as you wish at your own risk.
