最复杂的域名解析完整指南 - 手把手教你设置DNS记录
对于网站运营者来说，域名解析(DNS设置)是最基础也最关键的SEO技术环节之一。 一个正确的DNS配置不仅能确保网站正常访问，还能提升搜索引擎抓取效率。
Many website owners struggle with domain resolution(DNS setup), which is actually one of the most fundamental yet crucial SEO technical elements. Proper DNS configuration ensures website accessibility and improves search engine crawling efficiency.
为什么域名解析如此重要？
Why is Domain Resolution So Important?
如果把NS设置成托管型虚拟主机的服务器地址(如SiteGround)，域名解析将会非常简单。但如果你使用非托管主机或需要配置第三方企业邮箱，情况就会变得复杂。
If you set NS to managed hosting provider's server address (like SiteGround), domain resolution becomes very simple. But if you use non-managed hosting or need to configure third-party business email, the situation becomes complicated.
