حکم repeater رو داره. زمانی که در یک شبکه بزرگ، بخواهید دو بستر رو از یه منبع آدرس دهی کنید، از این سرویس استفاده میکنید.

توضیح کاملتر :

What is the DHCP Relay Agent?

The DHCP (for Dynamic Host Configuration Protocol) relay agent is a Bootstrap Protocol that relays DHCP messages between clients and servers for DHCP on different IP Networks. It can be a host or an IP router that “listens” to DHCP client messages being broadcast on the subnet and relays them to the configured DHCP server. The DHCP server would then send responses again using DHCP relay agent back to the DHCP client. The DHCP relay agent saves the administrator the agony of installing and running each DHCP server on each subnet. A DHCP server or a computer acting as a DHCP server is necessary for every IP network segment that has DHCP clients. These terms may sound a too wordy to some, so the definition of terms below may come as a relief.

DHCP-This is a client/server protocol that dynamically provides Internet Protocol (IP) addresses to hosts plus other configuration entries such as the Subway Mask and Default Gateway. Microsoft Windows Server 2003 OS has DHCP server service while Microsoft Windows 98, Millennium, NT, 2000, XP have DHCP client in their TCP/IP. One of the advantages of DHCP is that IP addresses are assigned from one central point minimizing the possibility of one IP being assigned to more than one computer which would create conflict.

* DHCP Server- This is a computer running the DHCP server service that has information as to which IP addresses are available as well as configuration information as defined by the administrator for DHCP.

* DHCP Client-This is a computer that receives its IP configuration information using DHCP.

مثلاً روی مودم adsl با آی پی 192.168.1.1 چه کاربردی میتونه داشته باشه وقتی dhcp فعاله و 10 سیستم از مودم آی پی گرفتن؟
منظور چه کمکی میکنه؟میشه دو رنج آی پی ست کرد رو سیستمها و هر دو از مودم اینترنت بگیرن؟

بزارید یه جور دیگه بگم!
یه مودم وایرلس داریم که آی پی ثابت روش ست شده و اینترنت هم روش کانکته
ویه آی پی ثابت هم دادیم به دستگاه دی وی آر واسه دیدن دوربین مداربسته
خوب حالا چطور میشه از قابلیت یازح اون و آی پی اینولید واسه استفاده موبایل و لبتاب از اینترنت مودم استفاده کرد؟؟؟
