Yes, it is worth setting up DHCP for two, five, or even twenty five computers as long as the computer has a newer operating system to support it. Dynamic Host Configuration Protocol is an important protocol that lets network administrators manage centrally and automate the assignment of IP configurations on a computer network. The way DHCP works is that the DHCP server receives the request, assigns a new address for a specific time period and sends it to the client. I think setting up DHCP for your computers is worth doing because it has its advantages over manual configuration. These advantages include that each computer gets its configuration from a "pool" of available numbers automatically for a specific time period meaning no wasted numbers. Domain Name System (DNS) A hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. Most prominently, it translates easily memorized domain names to the numerical IP addresses needed for the purpose of locating computer services and devices worldwide.…
In order to properly address the Infrastructure upgrade of the Kamazon Network our group decided that an appropriate ip address schema that will take into account the idea that people will be using more than just a desktop computer. They will have tablets, laptops, departmental printers, and smart phones. This is also based upon the understanding that every Department will have at least two printers for the staff and one for the Manager/Supervisor or VP of that Department. So with that being said, we estimated that could be at least three or more accurately four ip addresses per employee. So we multiplied the number of users per department by the number of estimated devices that each employee will be using.…
A simple design you can consider is 1 floor with a single data closet serving 150 users. You need a core network, networks for your firewall, DMZ, remote VPN clients, switch MGMT network, server network, voice network, wireless network and networks for other services you have not yet identified, like security, cameras, fire, door and video. You should have multiple domain servers and DHCP servers. While you can get away with using high end switches for DHCP, a couple windows servers will do the trick and give more insight when you are troubleshooting. Most systems can get along with DHCP, so that is fine, (some older systems still need host files) but there are support benefits to statically assigned addresses. In any case, you will want reserved space in these networks for your network devices, in exception to VLANs, redundant or clustered systems. For design, you could use the 10.1.0.0 address space using /21 (10.1.0.1 - 10.1.7.254) and for your subnet masking on the devices will naturally be 255.255.255. Reserve the first and last 20 or so addresses in each DHCP scope for statically assigned addresses and network devices / gateway addresses. Some examples would be, 10.1.0.0/24 for servers-all static, 10.1.1.0/24 for pc's printers usable for DHCP 10.1.1.21 - 10.1.1.230, 10.1.2.0/24 for wireless usable for DHCP 10.1.2.21-10.1.2.230, 10.1.3.0/24 for VoIP usable for DHCP 10.1.3.21 - 10.1.3.230 and 10.1.4.0 - 10.1.7.254 for future use. While you can cut back each network to a /25 giving 126 hosts per network, you may find yourself changing this sooner than expected.…
Having only two computers set up statically on a network will not be very time consuming having to change the setup if something on the network is replaced. Assigning client addresses automatically is by far the easiest option of the two. When setting up a DHCP server and leaving room for growth on the subnet you use, can also save time when installing new computers on the network. It would save the time of manually having to configure any new computers. Not to mention it takes way less time configuring a DHCP server than it would to configure each computer statically. Obviously you would want to pre-allocate IP addresses for fixed hosts such as routers, servers or even printers. These you would set up on the DHCP server as reserved addresses and set them statically on the devices.…
Routers these are the same setup as the firewall, by users to config the setting the one thing the company does not want to do is use the default setting for any router. Routers are the essential, but workhorses of modern computer networking yet few users realize they are computers, with their operating systems, software, and vulnerabilities.…
For two computers it’s not worth setting up a DHCP because when the two computers want to access the Internet, they will be provided the first available IP address. If you have five computers it would be a great idea to setup a DHCP because with setting up a DHCP you could set permissions which monitors what the other computers could access the Internet for, how long they could be logged in using the Internet and their activities. Now, if there were twenty-five computers it would be perfect to have a DHCP because each computer will have its own IP Address and the IP address would never expire. Also, with a DHCP you could get permission in what any users is able to do in their specific accounts between the network computer and you are able to monitor the daily activities of each…
Wired networking connections provide the foundation of the Local Area Network. Incoming connections, Data Center interconnections, IT closet facilities, and stationary computing devices have all traditionally been connected to the network via a series of cables. The primary benefit to a wired connection is that the wire provides a standard level of service (performance, security, reliability) which can be relied upon in all situations. Typically, wired connections (correctly installed) have an extremely low failure rate and provide a standard of service which helps provide a very low cost for support per connection. Once…

When it comes to installing Microsoft Windows Server 2008 R2, there are many different server roles that this software operating system has to offer. The first one is Active Directory Certificate Services and Active Directory Domain Services. Active Directory is a huge component when it comes to a server. This service has all the information about all of the users, the computers, and any other device that is connected to the network. The Active Directory assists IT professionals with being able to manage all of this information, and allows them to be able to facilitate any sharing that is going on between any end user in the company. Another role is the Active Directory Federation Services. This lets users have a web sign in capability, that lets users authenticate to different web applications by just logging in with one single user account. Another role that this has is the application server. This is a major role because the server can be used to hose and manage all of the critical business applications that the company needs to use. One major component also is the DHCP server, which the Windows Server does play a huge role in. The DHCP server is what assigns an IP address to any machine that is connecting to the network. This is critical because if the machine can’t get an IP address, then they won’t be able to communicate with the network. Along with the DHCP server, another role is the capability of being the fax server. This is self-explanatory, the fax server allows the company to send and receive faxes, and also allows IT personnel to be able to manage these jobs, or any settings or reports that are needed to be shown. Another major role is file services. The server basically holds all of the companies information, or software shares, so that when there is the need for a new install, or an employee needs a new piece…
