/**
 * 1108 - Defanging an IP Address\.
 *
 * Easy
 *
 * Given a valid (IPv4) IP `address`, return a defanged version of that IP address.
 *
 * A _defanged IP address_ replaces every period `"."` with `"[.]"`.
 *
 * **Example 1:**
 *
 * **Input:** address = "1.1.1.1"
 *
 * **Output:** "1[.]1[.]1[.]1"
 *
 * **Example 2:**
 *
 * **Input:** address = "255.100.50.0"
 *
 * **Output:** "255[.]100[.]50[.]0"
 *
 * **Constraints:**
 *
 * *   The given `address` is a valid IPv4 address.
