LookUpIP Description

LookupIP is a small and easy-to-use Windows utility for replacing numerical IP addresses by the host's domain name. It is mainly intended for webmasters who are looking for a fast and convenient way to process the logfiles of their Web servers. LookupIP is small, as fast as your network connection allows, it is free, and the source code is included! LookupIP has no graphical UI. Though it is invoked from Windows' command prompt, it is a real 32-bit application, not a DOS program. The program uses threads to concurrently look up multiple IP addresses. The faster your network connection, the more threads you can use. (But don't overdo it - most name servers are quite busy.) The next two parameters control LookupIP's DNS cache. All host names are stored in the file dns.txt in the same directory where LookupIP.exe resides. By default, a cache entry is deleted 90 days after the lookup. If the lookup failed, it is deleted after 14 days. (Failed lookups can be caused by a temporary or permanent DNS configuration error, or because the address owner does not allow reverse lookups.) Both filename parameters are optional. If both are present, input is read from the first and the converted output written to the second file. If only one is supplied, it is used as the input source, while the output is sent to the console. If no filename is given, input is read from the console, and output written to it. This is intended for input/output redirection using "" and "|".
