first. Fast fallback gives IPv6 connections a 250 ms head start so IPv6 is preferred on networks
where it's available.

To opt-in, configure your `OkHttpClient.Builder`:


```
OkHttpClient client = new OkHttpClient.Builder()
    .fastFallback(true)
    .build();
```

 *  New: Change the build from Kotlin-JVM to Kotlin-multiplatform (which includes JVM). Both

```kotlin
testImplementation("com.squareup.okhttp3:okhttp-dnsoverhttps:5.1.0")
```

### Usage

```
  val appCache = Cache(File("cacheDir", "okhttpcache"), 10 * 1024 * 1024)
  val bootstrapClient = OkHttpClient.Builder().cache(appCache).build()

  val dns = DnsOverHttps.Builder().client(bootstrapClient)
    .url("https://dns.google/dns-query".toHttpUrl())

 * Use [newClient] as a factory for a OkHttpClient instances. These instances are specifically
 * configured for testing.
