How can I copy the "clientIP" value to another array? because I need to compare them afterwards..
I managed to receive the remote IP address but I don't know how to save it.
Start with showing this code.
If you get the IP address as a string, that is not the same type as an IPAddress.
If you have the IP address as 4 bytes, you can simply declare two IPAddress variables, using the same 4 bytes.
If you want to copy the 4 byte array, use a for loop, and copy each element of the array.
