/**
 * Quick and dirty pattern to differentiate IP addresses from hostnames. This is an approximation
 * of Android's private InetAddress#isNumeric API.
 *

 *  Upgrade: [Okio 2.7.0][okio_2_7_0].

    ```kotlin
    implementation("com.squareup.okio:okio:2.7.0")
    ```

 *  Fix: Avoid log messages like "Didn't find class org.conscrypt.ConscryptHostnameVerifier" when
    detecting the TLS capabilities of the host platform.

 *  Fix: Don't crash in `HttpUrl.topPrivateDomain()` when the hostname is malformed.
