How to make a static ip

Projects Programming
1

can someone fill in the details (fake ip an key etc) so i can see a real example

is so confusing it just sais ip is there where i put the ip instead of ip or after it i dont know its unclear if you going to give example put fake details in so its an actual working ish example as i have no clue what it means there is no ay of knowing unless you already know!

I got an issue where its on the wrong subnet :confused: please someone clarify!

plsu way too many catagories i dont know what 1 to pick just make a couple cats not a mmillions!

Whilst I agree that there are many categories in the forum, your topic was certainly not an introductory tutorial and it has been moved here

Ok dw I fixed it on my own!

void loop(void){
  server.handleClient();
}

does anyone know how to also include a pincode option for extra security? so that ?statuts1=1&pincode=1234

that would be aswome if someone could help me figure that last part out?

but anyway i hope this post helps someone who needs a static ip and my code works so, if you got any use out ofit or know about how to put in a poincode let me know in reply please, thanks! ps il buy you a beer if you can help with the pincode part!

WiFiLocalIP example is about retrieving the local IP, not about setting the local IP

I suggest there is a better way to do this: Instead of setting a static IP address in your code allow your code to get an IP address by DHCP in the usual manner. Configure your router to supply the required IP address to the device. Most routers allow you to lock a specific IP address to the MAC address of a device, so the particular device always gets the specified IP address.

If you do it this way you can manage and change all your allocated IP addresses in one place, which is the router.

If you don't do this you still have to configure your router so as to make sure the allocated IP addresses are outside the range allocated to DHCP.
