The 1841 Integrated Services Router is a network appliance created by Cisco. Cisco 1841 offers high-performance, enterprise-class routing with some additional features such as hardware-based encryption and virtual network acceleration. Cisco 1841 series also has built-in DHCP (dynamic host configuration protocol) server functionality. When the cisco 1841 prix is configured to act as a DHCP server, it assigns an Internet Protocol address to each device that joins the local network. You can configure a Cisco 1841 to act as a DHCP server.
