The Functions of DNS and DHCP
Domain Name System (DNS) servers provide name resolution for network clients. DNS maintains information that links a computer’s fully qualified domain name (FQDN) to its assigned IP address(es). DNS translate domain names that are easily understood by humans, to numerical IP addresses. DNS is a vital component of the internet because it is a directory service. The DNS has been widely used since the 1980’s and provides translation services between it and the address spaces of the Internet Protocol. Dynamic Host Configuration Protocol (DHCP) provides the mechanism for automatically configuring client IP addresses, then it notifies the DNS server to update DNS records of that clients name to an IP address. DHCP configures the parameters of the IP addresses automatically from a DHCP server. With the help of DNS and DHCP, it takes a fraction of the time to configure IP address and domain names, which in turn saves money because of less man hours used. To answer the question of how many host does it takes to justify the time and effort to setup a centrally managed solution for name resolution and address allocation is two people, but that’s also is determined by whether or not the business has a LAN setup and has a server that will handle the request(s) for the additional IP address spaces. I would say that it is definitely worthwhile to take the time and

new feature in Windows Server 2008 DNS called Global Names Zone. The Global Names zone is a specially named forward lookup zone that is available when all the DNS servers for your zones are running Windows Server 2008. Deploying a Global Names zone creates static, global records with single label names without relying on WINS. This allows users to access hosts using single-label names rather than fully qualified domain names (FQDNs). (Stanek, 2008) When the domain and forest are operating at the Windows…

The majority of systems we use can work well with DHCP so it shouldn’t be a problem. Although some system will need hosts files, also you should have many domain and DHCP servers. Unit 1 Assignment 1. Windows 2008 Network Services In order for computers, printers, etc. to communicate with each other on a network, each must have a different IP address. To make remembering these easier, the Domain Name System (DNS) translates these numeric IP addresses into names and web addresses…

Week 1 Assignment 1 What role does TCP/IP play for Internet communications? TCP/IP (Transmission Control Protocol/Internet Protocol) is the basic communication language or protocol of the Internet. It can also be used as a communications protocol in a private network (either an intranet or an extranet). When you are set up with direct access to the Internet, your computer is provided with a copy of the TCP/IP program just as every other computer that you may send messages to or get information from…
