結論

動態主機設定通訊協定 (DHCP) 是由 RFC 1541 (這由 RFC 2131 取代),可讓伺服器動態分配 IP 定址及組態資訊給用戶端所定義的標準通訊協定。通常 DHCP 伺服器提供與用戶端至少這個基本資訊:
  • IP 位址

  • 子網路遮罩

  • 預設閘道
其他資訊可提供同時也如網域名稱服務 (DNS) 伺服器位址] 和 [Windows 網際網路名稱服務 (WINS) 伺服器位址。系統管理員會設定 DHCP 伺服器會剖析出用戶端的選項。

其他相關資訊

下列的 Microsoft 產品提供 DHCP 用戶端功能:
  • Windows NT Server 版本 3.5、 3.51 和 4.0

  • Windows NT 工作站版本 3.5、 3.51 和 4.0

  • Windows 95

  • Microsoft 網路用戶端版本 3.0 的 MS-DOS

  • Microsoft LAN Manager 用戶端的 MS-DOS 版本 2.2 c

  • Microsoft TCP/IP-32 的工作群組版本的 Windows 3.11]、 [3.11a,] 和 [3.11b
不同的 DHCP 用戶端支援它們可以接收來自 DHCP 伺服器的不同選項。如 Microsoft DHCP 用戶端所支援的特定 DHCP 選項有關請參閱下列的 「 Microsoft 知識庫 」 中的文件:
121005 支援的用戶端的 DHCP 選項
下列 Microsoft 伺服器作業系統提供 DHCP 伺服器的功能:
  • Windows NT Server 版本 3.5

  • Windows NT Server 版本 3.51

  • Windows NT Server 4.0 版
第一次之後設定為接收 DHCP 資訊初始化用戶端時, 它會啟始伺服器進行交談。

以下是用戶端和伺服器其後封包層級的描述的程序之間交談的摘要資料表:
   Source     Dest        Source     Dest              Packet
   MAC addr   MAC addr    IP addr    IP addr           Description

DHCPREQUEST

取得從 DHCP 伺服器用戶端的 DHCP 資訊會有與其相關聯的租用時間。使用期時間定義多久用戶端可以使用 DHCP 指派的資訊。當使用期到達特定里程碑時,用戶端會嘗試更新其 DHCP 資訊。

若要檢視 Windows 或 Windows 上的 IP 資訊,為工作群組用戶端,使用 [IPCONFIG 公用程式]。如果在用戶端就是 Windows 95,使用 WINIPCFG。

?考

DHCP 的更多有關,請參閱 RFC1541 和 RFC2131。 RFC 可以取得透過網際網路位於許多站台,例如:
