    I have been looking for a DHCP/Dynamic DNS server for a couple of years. My preference was a Linux based server. Since I am Ubuntu based, I didn't want to get involved with Active Directory and most of the Linux distributions had very complex setup and little documentation to implement. I ran across Dualserver late last year and decided to give it a try. I was not disappointed!! The software works great with dns (both static and dynamic) and dhcp. It was very easy to set up for my environment and works great out of the box. The documentation is very good and the configuration file is very well documented. I had a minor issue with my server and the developer was very quick to respond to my questions. ALL configuration is done through the dualserver.ini and I am able to run a primary and secondary server with complete integration. This far exceeded my expectations and I was able to get up and running in a few minutes. I recommend this highly!! If I had to offer any criticism, it would be maybe (just maybe) a graphical tool to help configure the ini file...

    Does just what I needed - which is to give me the capability to manage blacklists of web sites and domains for all the systems on my LAN through DNS. It ran fine out of the box on a Win 7 system but I had to modify the code to have it support many more wildcarded domains and to build it for x64 with VS 2015. The software scaled up to over 27,000 [WILD_HOSTS] and over 65,000 [DNS_HOSTS] entries without any noticeable delay, and frankly it still doesn't take up many resources. The number of warnings the code emits when built imply some less than enviable assumptions have been made about data sizes and I think it could be coded a little more cleanly overall, but all in all it's GREAT to have found this package and have been able to accomplish all my security and ad-proofing goals with it. Thank you to the original developers.

    @wenarlin If you look in the manual, there is a section about all the different DHCP options you can specify. One is Router. I think they just use the term router (which is what it is called in the DHCP spec) instead of default gateway which is what we are used to. I was thrown off at first myself.....

    This is very poor program, It is dont give default gateway to client machine, and dont have a single word "default gateway even in users manual... IT is useless

    Great jobs! Please add Hostname to the "Free Static Leases" of web. I think just one record per row is better.
