my pc is connected to a wireless router. my internet incoming connection is connected to the router.
I connected my arduino mega 2560 with ethernet shield to the router by wire.
Then I did IPCONFIG of my PC and get the ip address of my PC and the ip address of my router(gateway).
Accordingly I assigned suitable ip to arduino. It works and communicates with my CITECT scada.
Now I want that if the ip of arduino is assigned by router ( is it dynamic ?) and if is it changing? If the ip of router is assigned by ISP and if it is changing? But in scada i used the ip that i assigned to arduino ; means it is not changed? But i have idea that router assigns local ip to arduino and pc ? if the ip of router changes after some time then i have to change the gateway for arduino else it w’nt work.
finally tell me if the ip of router and arduino is changing or not?
thanks thanks thanks
