DHCP is one of the most commonly implemented network protocols in the world which is used to assign IP addresses to the clients automatically. DHCP reduces work of network Administrator from going to each and every workstation in the network to assign IP address. In addition, DHCP reduces IP addresses conflict issue. DHCP protocol uses 4 different packets that are exchanged between client and server to assign an IP address automatically. In order to examine DHCP packets, Wireshark will be used.

The domain naming server plays a vital role in the internet as it is needed and is involved in every internet application. DNS now works well and it is also sometimes mentioned that any new changes added to the present DNS may contribute to interruption to its functionality and can also contribute towards additional complexity which is undesirable. Current networks and the future networks relay essentially on DNS and it is important that the DNS should be a secured one. The DNS can be easily attacked and such an attack can cause dire consequences so it specifies the importance to use a secured version of DNS to avoid such consequences. To employ such a version involves more cost.

Dynamic Host Configuration Protocol (DHCP), allows a computer to join a network without a statically assigned Internet Protocol (IP) address (Mitchell, n.d., para 1). With DHCP a device can be assigned a unique IP address, as it joins the network (Mitchell, n.d., para 1). DHCP is done on a server, and parameters are set on the pool of IP addresses that can be assigned (Mitchell, n.d., para 4). In Server 2012 there are options to allow for fault-tolerance for DHCP. The three options available including, a failover cluster, setting up a split-scope DHCP, and a DHCP failover (De Clercq, 2014). It is recommended that Kris Corporation uses fault-tolerance for DHCP. The recommended method of fault-tolerance is DHCP failover, which is new in Server 2012. This option can replicate a complete DHCP scope to another DHCP server (De Clercq, 2014). When configuring there is an option to use a hot standby or to do load sharing (De Clercq, 2014). Hot standby uses one server as the active DHCP server, the second server is only used if the first DHCP server is not available (De Clercq, 2014). Load sharing uses both DHCP server at the same time, and the request are shared between the two servers (De Clercq, 2014). Load sharing is the default option, and the recommended option for Kris Corporation.

Remember to always think of the future. Once it’s all implemented and built, you can administer your network.

Under the article Intragrated IP address solution and management, this research concluded that IP address management provided abilities to manage, monitor, control and assign IPs space in a company. This greatly reduces costs and improves network uptime. The Core network services was another research done. Under this article, TCP/IP proved that more applications, users and even devices can run concurrently. This ensures that many tasks can be performed all the time. The article IPAM intelligence, it describes well how this protocol suite has led to fueling of new and intelligent approach to the IP address and management and thus improvement of this protocol suite. End-to-end service management was another article that was published proving how this protocol suite has enabled very high service performance and also availability. This is due to the fact that Telepresence and other real time service are easily accessible. Under the article File transfer ipv6 readiness, it was established that since the since ipv4 is running out, the introduction of ipv6 would be beneficial since it would be compatible with TCP/IP protocol suite. This would ensure that more data files would be transferred. Under the article Deploying new services with confidence, it was established that TCP/IP was a major contributor in deploying this reliable service. It was therefore important

In order to fulfill and meet WAI’s requirement and need for the next three years, I will recommend and provide a great tool, which comes and works well with the Windows Server 2012 and that is Hyper-V. It is one of the few tools with the features and services that meet this proposal’s requirements. In order to meet WAI’s requirement, Hyper-V needs to be deployed on all the servers in its entire network. For host processors and memory to work properly, Hyper-V will deliver World Advertising, Inc. with prolonged support. Furthermore, Hyper-V will allow WAI to operate its new servers and continues on benefiting of new hardware equipment and technology for its current and future virtualization. For reliability and security, I am planning on installing Server Core on all the servers in the network. Throughout the entire proposal and plan, there will be a total of ten servers installed in the WAI’s internal network. Moreover, to manage its entire network infrastructure (ground) work, I will mount and install Windows Server 2012 because it will permit WAI to accomplish and manage its entire Windows network infrastructure as a single server in its Boston location and four other servers

The internet and networks are expanding as many new computers and devices are being used. The configuration of both static and dynamic IP addresses should be simpler.

Internet grew rapidly over the last few decades. This has led to increase in the size of networks and number of network devices. The network infrastructure today needs improvement and changes daily, so adding new devices to network is very essential. The traditional way of assigning network configuration to clients with the help of a network administrator is difficult. DHCP has now owned the responsibility to perform this task. DHCP has its security issues because at the time of its development internet security was not as important as dynamic allocation of the network parameters were [2]. The major security concern in DHCP is interception of plaintext messages and illegitimate client or server that compromises the network.

Health Alliance is an organization found in July 2000 as a joint venture between Waitemata District Health Board and Counties District Health Board to provide non-clinical business services.

DHC is an open, industry-standard protocol that reduces the complexity of administering networks based on TCP/IP. It provides a mechanism for automatically assigning IP addresses and reusing them when they are no longer needed by the system to which they were assigned. It also provides mechanisms

IP Address Management (IPAM) - monitors, discover, and manage your IP networks that use DHCP and DNS. You can allocate, group, issue, lease and renew IP addresses in an organized fashion, an essential tools for keeping track of all IP addresses within your LAN and Network

Network design includes setting up security features and dealing with IP addressing structures. The extremely simple explanation of IP addressing structures is creating a system that gives every device on a network a unique ID. Those IDs let the computers on the network talk with each other.

After two labs focusing purely on the Linux side of systems administration and network services, this third lab puts Windows into the spotlight and how it deals with configuring services as compared to the previous RHEL-based configurations. Many of the same tasks which were completed using a RHEL 7 virtual machine in lab 2, such as setting up DHCP and DNS, are repeated in this lab on a Windows 2012 Datacenter virtual machine. This is done not only to show the differences in service administration, but also to indirectly teach students the steps as well as precautions that need to be taken when integrating in different enterprise server operating system families which very well could be running the same network services, such as in the case of this lab. Instead of merely just installing the same services and letting the clients make decisions on what data to receive from who, this lab also presents the challenge of making these two very different operating systems work together when the time comes to configure the DNS server on the Windows VM. A major point I took away from this is that while the Microsoft and ISC implementation of a DNS server can be seen as widely different, the integration of the two is very smooth and easy due to both of them still following the base rules of the DNS protocol as well as framework found in the numerous RFC’s which describe it. Active Directory, which is also installed on the server, was review at this point from multiple different

It is no doubt that almost everybody hears about IP address. Nowadays it is widely spread all over the world. IP address is shortened form of Internet Protocol (IP) address. A TCP/IP network is identified by IP address for device or computer. Internet and devices are connected with each other through IP protocol with sending information to each of them IP address. The IP address is not in computer, router, it is in field of interface. Nowadays we have got two types of IP address. These are IPv4( fourth generation of Internet protocol) and IPv6( sixth generation of Internet protocol).
