+# [1108. Defanging an IP Address](https://leetcode.com/problems/defanging-an-ip-address/)
+
+
+## 题目:
+
+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.
+
+## 题目大意
+
+
+给你一个有效的 IPv4 地址 address，返回这个 IP 地址的无效化版本。所谓无效化 IP 地址，其实就是用 "[.]" 代替了每个 "."。
+
+
+提示：
+
+- 给出的 address 是一个有效的 IPv4 地址
+
+
+
+## 解题思路
+
+- 给出一个 IP 地址，要求把点替换成 `[.]`。
+- 简单题，按照题意替换即可。
