Suggestion: retrieve ip address if ping to host was successful about esp8266ping HOT 4 CLOSED

Hi!

To resolve the ip address the library use the WiFi.hostByName() function, like this:

bool PingClass::ping(const char* host, byte count) {
    IPAddress remote_addr;

    if (WiFi.hostByName(host, remote_addr))
        return ping(remote_addr, count);

    return false;
}

I have to think about a way to return some data in a prettier way, including host IP, average time, success rate, etc.

In the meantime you can mimic the function above in your code, saving the return value of WiFi.hostByName()!

Thanks for your prompt reply. Yes, that's what I am doing right now. But doesn't that call initiate another dns request?

Ping.ping() also accept an IPAddress instead of a host string.

So, if you call hostByName in your code, and then pass the resulting IPAddress to Ping.ping(), only one DNS request will be made.

There's also an example (https://github.com/dancol90/ESP8266Ping/blob/master/examples/SimplePing/SimplePing.ino) that uses directly an IPAddress.

Ah! Got it. Thanks!
