In addition, because DHCP is not aware that you have "fixed" the IP address at the server you run the risk of a conflict. Many consumer routers will not have the ability to exclude a single address from within the DHCP range of addresses for lease (known as a 'pool'). I'll assume we're looking at a typical home / SOHO setup since you mention your router is providing the DHCP service.
There was also Cisco router at 192.168.1.4 which appeared for some business communications service, but I had no credentials to access it.ĭHCP services differ across many possible implementations, and there are no ranges of IP that are traditionally reserved for static addresses it depends what is configured in your environment. It could be the reason why it lists the IPs as static although they're dynamic.

The router seems to be using DHCP by default, but remembers the devices that were connected to it (probably using their mac address). I must admit that the way the router display things keeps some parts a mystery. 192.168.1.1 (= IP of the router)įor details, see my answer to Michal's comment at the bottom of this message.

On any Windows computer connected in DCHP, ipconfig /all shows something like: IPv4 Address. IP addresses attributed to the computers are outside of the very narrowĭHCP range of 192.168.1.33 to 192.68.1.35.The router's setting "Enable DHCP on LAN" is set on "Off" but the IP addresses are obtained in DHCP.Although all IP addresses are all obtained in DCHP, they are displayedĪs by the router as if they are static addresses.The list of connected devices is something like Description IP address MAC address The IP and the MAC addresses that I can see with the ipconfig all command in Windows match those in the list of connected devices that the router displays, so that I can confirm who is who. When booting any computer, it obtains its IPv4 address in DHCP. Nota bene: There is also an IPv6 section. Router's overview panel:Ĭonnectivity type is set to DHCP and PPoE.ĭHCP range starts at IP address : 192.168.1.33ĭHCP range ends at IP address : 192.168.1.35 I could access the router's configuration. Thank you for the many good answers, especially the very detailed one from Liam. My beginner's question doesn't relate to commands but to general principles and good practices. Or are there some ranges of IP that are traditionally reserved for static addresses? Should I simply assign the server this same IP as fixed and configure the router so that it will exclude this IP from the ones available for DHCP? Each restart of the loop, it reads the state of the button again, but if it isn't pressed, the if statement never activates, the lights never change, and the program restarts again.I want to assign a fixed private IP address to a server so that local computers can always access it.Ĭurrently, the DHCP address of the server is something like 192.168.1.66. Once 15 seconds is over the loop restarts.

Much like the pull-down resistor for the button, this simple check stops the code detecting minor interference as a button press.īy waiting inside the if statement for 15 seconds, the traffic lights can't change for at least that duration. You may be wondering why the button checking happens twice ( digitalRead(button)), separated by a small delay. The specified language : clike does not exist' Code generation failed!!'Ĭhange the entire loop function to the following instead: The specified language : clike does not exist' Code generation failed!!'
Without this initial setting, they would off until the first time changeLights runs. Add a line to set the traffic lights to the green stage. Now, in the setup function, add a new line to declare the switch as an input. Start by adding a new variable to store your button pin: The specified language : clike does not exist' Code generation failed!!' Now, in the loop part of the code, instead of changing the lights every 15 seconds, you're going to read the state of the pushbutton switch instead, and only change the lights when it's activated. In other logic circuits, you may find a pull-up resistor instead, and this works on the same principle, but in reverse, making sure that particular logic gate defaults to high.
