Make recommendations about DNS Server. Configure DNS. Configure DHCP. Unit 2 Configuring and maintaining the dhcp and dns server roles Key Concepts DHCP for TCP/IP Address Management DNS Concepts Configuring DNS and DHCP Troubleshooting Using DHCP for TCP/IP Address The DHCP Server Role (TCP/IP Model) Remember from Unit 1 Each Host Must Have a Unique IP Address Accomplished in Two Ways Manually Assign IP Address (Small number of users) Dynamically or Dynamic Host Configuration Protocol (DHCP) (Large number of users) Additional Requirements Gateway Allows Hosts to Communicate on Separate Subnets DNS Server To Translate IP Addresses into Friendly Names (www.google.com) Using DHCP for TCP/IP Address The DHCP Server Role Windows Server 2008 Provides A Central Administration Tool to Dynamically Allocate IP Addresses to Hosts DHCP Server Role Tracks all assigned IP addresses Allows centralized changes Updates and propagates DNS server addresses to DHCP clients Extremely flexible and scalable (small and large environments) Provides Configuration Parameters E.g. Gateway and DNS Servers Using DHCP for TCP/IP Address Break up into groups of 4 and discuss possible situations where static IP address assignment might be beneficial and/or required. (10 minutes). Give a 2 minute summary of your discussion and justify your reasoning. Using DHCP for TCP/IP Address Understanding DHCP Key Function of DHCP is Dynamic Address Assignment Relies Heavily on UDP User Datagram Protocol UDP is a Transport Layer Protocol Utilizing Server Port 67 and Client Port 68 Key Components of a DHCP Infrastructure DHCP Servers (a computer that provides DHCP configuration to multiple clients) DHCP Clients (computers that obtain DHCP configuration information from DHCP servers) DHCP Leases (the length of time a DHCP server assigns configuration information to a DHCP client).
