### 網域名稱 { #domain-name }

通常會先**取得**一個**網域名稱**，接著在 DNS 伺服器（可能是同一個雲端供應商）中設定它。

你可能會租一台雲端伺服器（虛擬機）或類似的服務，並擁有一個<dfn title="不會隨時間改變；非動態的">固定</dfn>的**公用 IP 位址**。

在 DNS 伺服器中，你會設定一個紀錄（「`A record`」）指向**你的網域**所對應的**伺服器公用 IP 位址**。

這通常在初次建置時設定一次即可。

/// tip

「網域名稱」是發生在 HTTPS 之前的事情，但一切都依賴網域與 IP 位址，因此在此一併說明。

### DNS { #dns }

現在聚焦在實際的 HTTPS 部分。

首先，瀏覽器會向 **DNS 伺服器**查詢該**網域的 IP**，例如 `someapp.example.com`。

// along with this program.  If not, see <http://www.gnu.org/licenses/>.

package dns

import (
	"path"
	"strings"

	"github.com/miekg/dns"
)

// msgPath converts a domainname to an etcd path. If s looks like service.staging.skydns.local.,
// the resulting key will be /skydns/local/skydns/staging/service .
func msgPath(s, prefix string) string {
	l := dns.SplitDomainName(s)
	for i, j := 0, len(l)-1; i < j; i, j = i+1, j-1 {

        override fun peek(): MockResponse = TODO()

        override fun shutdown() = TODO()
      }
  }

  @Test
  fun dns() {
    var dns: Dns = Dns { TODO() }

    val system: Dns = Dns.SYSTEM

  fun eventListener() {

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.
