TweakDUN : Java Glossary

I have left this tombstone entry for historical interest.


Was a free program that let you fine tune the way TCP/IP (Transmission Control Protocol/Internet Protocol) works, e.g. the MTU (Maximum Transmission Unit) packet size. It also provided a convenient editor for the hosts. file which maps DNS (Domain Name Service) names to IP (Internet Protocol) numbers. However, its main function was keeping the IPs in the hosts file up-to-date. 

I wrote a replacement for TweakDUN that handles just this IP-updating function called QuickDNS which works only on XP, W2003, Vista, W2008, W7-32, W7-64, W8-32, W8-64, W2012, W10-32 and W10-64.

TweakDUN would automatically find it for you and automatically update entries. You put entries in the hosts. file either because they are not real DNS names, (e.g. localhost ), or because you use them so often you want fast lookup, e.g. or

Unfortunately TweakDUN had serious bugs (If ever it failed to find a name on lookup, all subsequent lookups of good names fail as well and it did not work on Vista). The author lost all interest in supporting the product and then the website itself went south.
