ステップの初めは、**ドメイン名**を**取得すること**から始まるでしょう。その後、DNSサーバー（おそらく同じクラウドプロバイダー）に設定します。

おそらくクラウドサーバー（仮想マシン）かそれに類するものを手に入れ、<abbr title="変わらない">固定の</abbr> **パブリックIPアドレス**を持つことになるでしょう。

DNSサーバーでは、**取得したドメイン**をあなたのサーバーのパプリック**IPアドレス**に向けるレコード（「`Aレコード`」）を設定します。

これはおそらく、最初の1回だけあり、すべてをセットアップするときに行うでしょう。

/// tip

ドメイン名の話はHTTPSに関する話のはるか前にありますが、すべてがドメインとIPアドレスに依存するため、ここで言及する価値があります。

### DNS

では、実際のHTTPSの部分に注目してみよう。

There may be many routes for a single address. For example, a webserver that is hosted in multiple datacenters may yield multiple IP addresses in its DNS response.
