The `IPAddress` class has a member function `bool fromString(const char *address)`.

```
const char *apipch = "192.168.4.1";
IPAddress apip;

if(apip.fromString(apipch)){ // try to parse into the IPAddress
	Serial.println(apip); // print the parsed IPAddress 
} else {
	Serial.println("UnParsable IP");
}
```
