Abstract: Embodiments of the present invention disclose a method, relay agent and system for acquiring an IP address in a network. According to the method, the relay agent configures multiple gateway IP addresses corresponding to a type of a client, adds the multiple gateway IP addresses to a DHCP Discover packet of the client, and sends the DHCP Discover packet to a DHCP server, so that the DHCP server allocates an IP address to the client, and sends a DHCP Offer packet to the client after determining that one gateway IP address in the multiple gateway IP addresses belongs to a same network segment as the allocated IP address, so that the DHCP server allocates the IP address to the client, thereby implementing that multiple IPs in different IP address segments are allocated to a same DHCP client type.

Abstract translation: 本发明的实施例公开了一种用于获取网络中的IP地址的方法，中继代理和系统。 根据该方法，中继代理配置与客户端类型相对应的多个网关IP地址，将多个网关IP地址添加到客户端的DHCP Discover数据包，并将DHCP Discover数据包发送到DHCP服务器， DHCP服务器为客户端分配IP地址，并在确定多个网关IP地址中的一个网关IP地址与分配的IP地址相同的网段后，向客户端发送DHCP Offer数据包，以便DHCP服务器分配 到客户端的IP地址，从而实现不同IP地址段中的多个IP被分配给相同的DHCP客户端类型。
