IP addressing scenario Essay Example for Free

IP addressing scenario Essay According to the scenario, the company will have a single, physical location with approximately145 hosts on the network. In this case, I would suggest using a class C address such as 192. 168. 0. 0. Reason why is because you can put all the devices on a single subnet with the subnet mask 255. 255. 255. 0/24. This would allow for 253 usable host addresses, which is more than needed in this case. Whether you should dynamically or statically assign those IP’s goes, I suggest assigning it dynamically. Unless you don’t mind MANUALLY managing 218 hosts, you should definitely go with DHCP. The router will be well capable of handing out addresses for 145 hosts. Since there is only one location used in this case, only one network should be used as it will only complicate things to have more than one network. Since DHCP is being used as the suggestion, whether we should use a router and/or firewall, or utilizing Windows Server†¦the answer is yes. The router for dishing out the IP addresses and the firewall should be used for security purposes. Using Windows Server just for DHCP is rather overkill. Using these suggested methods should also accommodate for at least 50% growth within the next few years. Windows 2008 Network Services To understand the functions of DNS and DHCP, first we must acknowledge their necessities. Humans in general are fairly decent at remembering certain numbers, like home addresses, phone numbers, and Social Securities. And even those simple tasks are becoming difficult for us because of technology doing all the remembering for us. We are becoming lazier and more dependent on computers. If we can’t even do these menial tasks efficiently, how would you expect us to remember dozens of IP addresses for websites? This brings to a solution. Also known as name resolution, it allows us to enter the name of a website, and then the resolution service finds the IP address for that website and directs the request to that address. Domain Name System is the service that provides name resolution on networks and the Internet. When you specify a site address in your browser on your local network, a DNS server intercepts that request and checks its cache. If the IP address is in the cache from a previous request, the request is completed and your browser is directed to the IP address. If the address is not in the cache, DNS makes a query to the next DNS server above it until a server in the upstream chain is able to return the address. Dynamic Host Control Protocol is a service that automatically assigns IP addresses to devices that connect to the network. If a device is configured to automatically obtain an IP address, it sends out a request for an IP address when it connects to a network. The request may get more than one offer of an IP address, and the computer typically accepts the first offer that it gets. This relieves the network administrator of having to manage each device. Setting up a DHCP is really not necessary for either 2 computers even 5 computers as you could easily assign them statically. However, when it comes to managing 25 computers, I would absolutely assign it DHCP as it may become confusing have to track that many different devices.
