Lab 3 TCP\IP networking communication protocols 1. Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address to a physical machine address that is recognized in the local network. 2. The DHCP is used to distribute the main IP and create subnets for all additional computer connected to the same network. The DHCP server will be connected to the router and switch; it will distribute specific IP address to each individual computer so they can all be identified. 3. The

go a long way toward helping you figure out where to start looking for the problem. For example, if everyone in the company is having problems, you might look for a hardware failure on your VPN server, an incorrect firewall rule, or perhaps a configuration problem on your VPN server. On the other hand, if there is only one person who is having a problem who can never seem to remember his/her password or Some other person who insists on connecting from their home computer, that too can tell you a

Project 2: Virtual Network Design Jaime Galena ITCS-408 Mr. Shu 12-12-14 Western Dynamics is a midsized specialty manufacturing company. They have decided that a virtualized environment would help reduce costs and provide for a smaller carbon foot print. As the company’s first step in this direction, they have decided to move two of their current physical domain controllers into a virtualized environment. The company expects this system to

Lab #1 – Assessment Worksheet Assessing and Securing Systems on a Wide Area Network (WAN) 1. What is the first Nmap command you ran in this lab? Explain the switches used. The first nmap command used was nmap -O -v 10.20.100.50. -O was to detect the operating system of the 10.20.100.50 machine, while -v showed much detail. 2. What are the open ports when scanning 192.168.3.25 and their service names? There are twelve open ports. 80 is HTTP services, 135 is the Microsoft EPMAP aka DCE/RPC

This is newest updated file from today. See below. IP Subnetting Project XUMUC is has the WAN links in place to the new locations in the Houston Region. XUMUC currently has 2 other Regions San Francisco and Denver. Originally, XUMUC was only in one region (San Francisco). The previous consultant did a poor job with the integration resulting in a poor IP address scheme as a result routing tables at the summarization points and at the San Francisco Campus are very large. In addition, no VLAN

In reference to IT-management overhead, DNS and DHCP servers can be very helpful in several ways. The services that these two types of servers offer are crucial in many environments but for simple or smaller networks it is not always necessary to focus on setting them up within the local area network. The services that DNS servers provide eliminate the need to memorize or keep track of multiple numeric IP addresses and allow us to use more user-friendly names or domain names instead. In order for

Using only the following protocols (ARP, DNS, HTTP, ICMP, IP, NTP, RTP, UDP, TCP), describe the steps involved when the Internet host red.color.net pings another host green.paint.net. Describe this step by step, in detail- what happens in each host. Assume all caches are empty (i.e. No name or address resolution has been done, yet) You have to think through the whole chain of how address discovery works and what protocols are used at every step. Let red.color.net be Host A with IP Address 192.168
