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.…
Computer A is trying to send information to Computer B, the IP address must see the advertisement from Computer B for the router to know where to send the information. The router then…
The scenario is I am an IT Administrator for a newly founded company and have been tasked with designing am IP addressing scheme and a plan for allocation and management of IP addresses. The company will currently have a single, physical location with approximately 145 hosts (computers, printers, etc.). IT plans should accommodate 50% growth in the next 2 years.…
The Remote Access will provide the Virtual Private Networks with services that the users can use to access the corporate networks over the Internet as it they were directly connected. This remote access will enable the remote…
DHCP eliminates the need to assign static IP addresses by allowing a server to assign addresses to devices as they connect to the network.…
IP router: A device that performs IP routing. A physical device with roles defined by the IP protocol, including to connect LANs and WANs using its physical interfaces, and to route (forward) IP packets that come in any interface out the correct outgoing interface.…
8. Why is it unlikely that you will fi nd the IP address 192.168.250.10 on the Internet?…
In this lab we set up default routers for the router. This was a continuation for me from last semester, but this is something I struggled a little bit with it. This is important in my field because this is a common job for someone that does the work that I am looking to do.…
9. If no DHCP server is available when a computer configured for dynamic IP addressing connects to the network, what type of IP address is assigned to the computer? Automatic Private IP Address (APIPA)…
We show how incremental deployment of such routers can make the Internet safer. Like all things dynamic, change is inevitable. Such is the case with your network environment. Upgrades and modifications to the network architecture can sometimes expose, or create security holes. Hardening a network does not always mean spending large amounts of money. Whether that means spending it on new hardware, software, or man hours really depends on what needs to be addressed. It may include all of the above. The time may come when a cost/benefit analysis will be required by those in charge before hardening activities can move forward. As such it's important to point out some of the non-technical benefits of network hardening for the business as a whole.…
Currently the security for the internet server and the location of it in the network is not as protected as it should be and it is not the best design either. The internet server must be located out of the company firewall to protect the systems and network internally. By doing this it separates the remote server system the system has proper validation and connection through the system allows access to the rest of the network. Staffs that are located in the firewall can authenticate through a proxy system and then access the internet, which in turn allows them to communicate…
A router is a type of hardware device designed to receive, analyse and transfer incoming packets of data to another network. It can also convert data to another network interface. There are two types of router, router and the wireless router. The main purpose a router is to connect multiple networks and transfer information to own networks or other networks. The router also prevents data from going where its not…
Every device that sends IP packets must have an IP address. Those include every PC, phone, tablet, and other electronics such as smart televisions and game consoles. IP addressing does not happen automatically, it must be planned. To plan what IP addresses to use, you must follow some rules for IP addresses. One of those rules states that IP addresses identify an interface connected to a LAN or WAN. Another rules requires that IP addresses exist as groups.…
It is very important to go through the process of hardening. Hardening is where you change the hardware and software configurations to make computers and devices as secure as possible. I picked the network layout 1-the workgroup . First with the workstations and laptops you need to shut down the unneeded services or programs or even uninstall them. I would also have some good anti-virus software on the workstations. You also need a hardened image for all of your workstations. To do this you need to install a new copy of the operating system and then harden it. After you have one good hardened workstation you can use it as a model for all other workstations and also laptops. For the router you definitely need to protect it from unauthorized access. The router needs to be password protected and you should periodically change that password. For the cable modem you should keep all unwanted ports closed. I would also schedule a regular scan of all the systems. Now for some of these next things I am talking about they will apply to all devices . Disable remote administration. Administration of your router / access point should be "local only", namely, there is no reason to let people from another country access to your network hardware. If you need to make changes, you should be local to the device. Update the firmware. Believe it or not, consumer network hardware needs to be patched also. Check the support site of the vendor of the device when you get it and check for an update. Sign up for e-mail alerts for updates, if available, or check back on a regular basis for…
