Free lookups software for windows

LookupIP is a Windows tool for replacing numerical IP addresses by the hosts domain name LookupIP is a small and easy-to-use Windows utility for replacing numerical IP addresses by the
hosts 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 dont overdo it - most name servers are quite busy.)
The next two parameters control LookupIPs 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 "|".

Alpine is an "Alternatively Licensed Program for Internet News and Email" intended to be an easy-to-use program for sending, receiving, and filing Internet electronic mail messages and bulletin board (Netnews) messages.

Take Alpine for a test drive to see what it can actually do for you!

Enhancements

• Redesigned Web Alpine interface
• Experimental S/MIME support added in UNIX versions of Alpine
• Attempt to include the attachment filename as part of the name of the temporary file used when viewing an attachment with an external program. Add some randomness to that filename to make it hard to predict the filename. Add a filename extension, usually derived from the type/subtype, to the temporary filename.
• Enhance address completion in the composer (TAB command) so that it looks through nicknames, fullnames, and addresses from the address book; addresses from the message being viewed, if any; and the results from LDAP Directory Server lookups for all of the defined directory servers that have the "Use-Implicitly-From-Composer" feature set.
• Make the default character set setting more liberal in what it will accept from the UNIX nl_langinfo call and the various values of LANG seen in the wild
• Remove the Alpine revision number from the titlebar in released versions

LDaemon is an LDAPv3 server based on open source technology LDaemon is an LDAPv3 server based on open source technology. It is designed to run as a Windows 2000 system service and provide full LDAP server functionality for MDaemon customers.
The purpose of LDaemon is to create an LDAPv3 platform for use as both
a shared database backend for a network of MDaemon servers and also as
a simple address book provider for LDAP capable email clients.
MDaemon can be configured to use an LDAP server (LDaemon) to store its
account database information. When so configured, a network of MDaemons
each using the same LDaemon server can be created in order to distribute the workload while sharing user database information. Also, LDAP tools can be used across a network to create and manage MDaemon email accounts.
LDaemon can be used as a simple address book provider for email clients
which support LDAP lookups. MDaemon will publish and maintain its internal addresses automatically by transacting data directly with LDaemon. When you perform an LDAP search with your email client you will have access to an up to date list of accounts for your local address book within your mail client.
