DHCP Server is an application that deserves a spot on my recommended software list; in fact, it has saved me in various situations, especially when I couldn't communicate with the device in question.
A typical problem
After configuring aHager TJA450, a server specific to home automation using the KNX protocol, I allowed an IP address from the client's administrative network to be assigned via DHCP. A few months later, at the client's request, I needed to make some programming changes to the server. What was my problem? I couldn't reach its IP address in any way!
The solution to this problem?
I didn't have a router with me that could automatically assign an IP address to my computer via DHCP and another IP address via DHCP to the Hager TJA450 server, which would allow me to communicate with the server. When no other solutions came to mind, a light bulb went off—I wondered if there was an application to create a DHCP server, given that there are all kinds of servers, like FTP file servers, Apache or Nginx web servers, etc. Yes, I was right—there was software to run a DHCP server.
After installing DHCP Server, I chose the network adapter and the range of IP addresses I wanted to use, connected an Ethernet cable between my computer and the Hager TJA450 server, and immediately started communicating with it.
I was able to program what the client requested.
About DHCP Server
It's free, lightweight software that runs in a Windows environment. The configuration is stored in an INI file, as is the database, so there's no need to install any database software to support DHCP Server.
