隆重推出 dns.toys，这是一款独特的域名系统 (DNS) 服务器，旨在通过命令行方便、轻松地访问各种实用程序和服务。通过使用 dns.toys 而不是典型的 Web URL，您可以简化任务，例如检查当前世界时间、转换货币、确定可用的 CIDR 范围、生成随机数等等！甚至还设置了一个名为“dy”的别名以方便使用。该资源仅为娱乐目的而创建，为用户提供有用且简单的可访问性。但请注意，dns.toys 提供的任何服务均不保证其准确性、及时性、可靠性或适合特定需求。尽管如此，凯拉什·纳德提供这些资源完全由他承担费用和责任。如果有帮助就使用它；我们希望如此！

如前所述，“nslookup”默认包含在 Windows 中。这是使用“nslookup”的示例。要对域名执行反向 DNS 查找（即获取与 IP 地址关联的主机名），请输入以下命令，然后按 Enter： ````` nslookup 172.26.212.1 ````` 根据您的需要替换最后一行（指定域名/主机名/IP 地址）。另一个 DNS 客户端也是“host”，如果需要，可以单独找到并下载。不过，如前所述，`nslookup` 和 `host` 在 Windows 上已经存在，因此不一定需要单独获取。对于 Windows，其他 DNS 实用程序包括用于检查 DNS 设置的“powershell Get-DnsServer”以及 PowerShell 模块“DnsClient”。然而，这些是单独的实用程序。关于帖子作者提供的 DNS 玩具，使用 DNS 本身而不是特定的库或语言绑定执行 DNS 查询的好处包括： 1. DNS 提供跨平台兼容性，因为 DNS 由于网络而几乎无处不在。因此，通过 DNS 本地运行此类 DNS 查询并不依赖于其他方式检索相同信息通常需要的第三方软件或库。相反，使用 DNS 提供了更精简的设计模式，因为它消除了管理多层通信的要求。 2. 鉴于其可扩展性，DNS 允许有关 DNS 解析行为的高度灵活性。此外，在 DNS 中本地实现 DNS 功能可以解决在采用其他机制时常见的兼容性问题（典型的是围绕标准化 DNS 功能，从而增加通信通道的开销）。

Why not? For fun. I spend a lot of time on the terminal and doing quick unit conversions, weather checks etc. without having to open a clunky search page is useful.
