...IP addressing Scenario When you design an IP addressing scheme for a medium to large scale company you need to take into account several questions about the company environment. What type of security is needed? Is the company going to grow past 145 clients? Do all the computers need to talk to one another? Can they be separated out into different departments? What types of content will be shared between users? How many content share servers are there? When setting up an IP scheme you need to take into account the growth of the company. If the company is only going to have 254 devices attached to the network. If the answer is yes then you can proceed with a statically assigned IP scheme. If you answer is no then you need to implement a scheme designed around a DHCP server. Normally when you design a scheme you want to take into account the departments in the company and if they need to be interconnected to the rest of the clients. If there are several departments that need to talk to one another, and a couple of departments that are restricted access clients. These types of question and answers would make an IT professional’s job either simple or more complex. Normally in a IP Scheme you want to choose the IP address that make sense to your network most internal networks sit in the class B or C range. If you choose a network IP of 172.16.0.1 your subnet masks would be at 255.255.0.0 for your choice. If you are going to design a IP scheme around a DHCP Server it might be...

...IP Addressing Scenario The first thing that we must take in consideration is the number of hosts (145). For my design, I could use the 192.168.0.0 address space using /21 (192.168.0.1 - 192.168.7.254). My subnet mask on the devices will be 255.255.255.0. I will reserve the first and last 20 or so addresses in each DHCP for statically assigned addresses and network devices / gateway addresses. * 192.168.0.0 /24 for servers-all static * 192.168.1.0 /24 for pc's printers- operational for DHCP 192.681.1.21 - 192.168.1.230 * 192.168.2.0 /24 for wireless - functional for DHCP 192.168.2.21-192.168.2.230 * 192.168.3.0 /24 for VoIP - working for DHCP 192.168.3.21 - 192.168.3.230 * 192.168.4.0 - 192.168.7.254 for future usage . We should have multiple domain servers and DHCP servers. Firewall always needs to be used even though most computers with windows 7 come with it. Firewall is very important because it block any outside intrusion. That way it can be monitored. All type of security can be implanted to assure that the servers can’t be infiltrate by intruders, like finger print recognition, password expiration…. It will be my responsibility to ensure that all policy regarding the security of each computer and server will meet the criteria. Each IP addresses should be addressed dynamically because it will be easier and it won’t take a lot of time and that way we won’t have to go to each computer and assign them statically. The only that we will have to assign...

...UNIT 1: IP ADDRESSING SCENARIO First to start off with this scenario you should think about the design. When designing I would use one floor with a single data closet. This will be able to have one hundred and fifty users. There’s a list of equipment and software that’s needed. A core network, networks for your firewall, server network, voice network, wireless network. Also networks for other services you have not yet identified, like security, cameras, fire, door and video. The subnet range would be one-hundred and forty five from one-hundred and forty six. The network number would be one-hundred and forty four. Also the broadcast number will be one-hundred and forty seven. In this case as far as which class it would be is class B. In the case of the how the IP addresses would be assigned I would consider choosing statically. A static IP address is a number that is assigned to a computer by an internet service provider to be its permanent address on the internet. Also an advantage of having statically IP addresses is that they’re easy to use and less expensive. When it comes to maintaining and obtaining they’re easier to have as well. In answering the question about having one or more network/subnets to be used, I would think that you should use multiple network or subnets just in case you want to expand the size of your IP addresses. If you keep everything at its minimum size or space then that’s all you have to work with. If you make sure that you have extra space, host...

...NT1330 Client-Server Networking II Name: Homework 1 Ch. 1 (70-642): Introduction to Networking Concepts Fill in the Blank: 1-10 The most widely used IP addressing scheme is IPv4. The most recent and largest address space IP addressing scheme is IPv6. To distribute IP addresses automatically, a network administrator would configure the DHCP service. The first attempt at breaking up IP address space used classful addressing to provide address ranges of differing sizes. Prior to the introduction of the Domain Name System, computers used HOST files to map human-readable named to IP addresses. A(n) Subnet Mask is used to separate the host address portion of an IP address from the network address. The subnet mask within the TCP/IP configuration is used to distinguish the network address from the host address. In dotted-decimal notation, each IPv4 address is broken up into four octets. Server computers and other systems that need to be accessed reliably by network clients should be configured with a(n) static IP address. The method of breaking up IP address space into address ranges of flexible size is called CIDR .

...IP Addressing Scenario Unit 1 Exercise 1 ITT Technical Institute Floyd Washington Jr. April 4, 2015 When setting up a network that will consist of many host computers, one of the first things that an administrator must do is to determine what class of networks that they must administer to a given business. This is the point where every administrator must know how to implement classful and classless IP addressing. A classful network is a network addressing architecture used in the internet from 1981 until the introduction of Classless Inter-Domain Routing (CIDR) in 1993. Classful IP addressing divides the addtess space on the internet into five address classes. Each class is coded in the first four bits of the address. Today the classful network concepts remain in play only limited scope of the default configuration parameters. There are 32 bits contained in any IPv4 IP address. A Class A network has eight bits in the network number field and 24 bits in the rest of the field and covers a range of 0-126 in the leading field. There are 128 Class A networks with 16,777,216 hosts capability per network. The range of the Class A networks are 0.0.0.0 to 127.255.255.255. A Class B network has 16 bits in the network number field and has 16 bits in the rest of the fields and covers a range from 128.0.0.0 to 191.255.255.255. There are 16,385 Class B networks and each network has the capability of having 65,536 network hosts. A Class C network has 24bits in the network number...

...Theren Woods 9/24/2015 NT 1210 Unit 1. Exercise 1. IP Addressing Scenario A design for a 1 floor office with a single data closet serving 145 to 254 users would need a core network, networks for firewall, a switch management network, a server network, voice network, wireless network, and a network for future services to accommodate the potential 50% growth the company intends to happen. The subnet range that should be used to accommodate 145 hosts plus a potential 50% growth within the next two years should be 255.255.255.0. This subnet mask range would support 254 hosts and this particular scenario is only planning for no more than 218. The IP addresses should be statically assigned because dynamically assigned IP addresses can change each time you connect to the internet but statically assigned IP addresses are reserved for the user and don’t change over time. Statically assigned IP addresses would definitely be best for an office environment because you want the same IP addresses everyday so the computers can talk to the server and with one another daily. You should have more than one network/subnets for computers, printers, future use and other host that may be needed. If DHCP is used you should use a Windows Server because it is safer. Normally a hacker will try to penetrate your router or firewall first so if that happens they will also have your DHCP. If it is on a server that’s another added layer to try and hack...

...AD Design Replication Scenario To add two new branch offices we will need to find a strategy to design a replication process. To implement this we will need to use intersite replication. Intersite replication is needed when adding domain controllers located in different sites. We will also need a site link in order for replication to take place between the various locations. A site link is a logical, transitive connection between two sites that allows replication to occur. We will need to take into consider the cost, schedule, and frequency. It’s best to set the schedule for the site link during off-peak business hours. This will ensure the bandwidth is not bogged down on the WAN, due to replication traffic. Frequency will determine how often information is replicated over the site link. Before installing the new domain controllers and before we begin the replication process, we will need to setup the IP addressing or sub netting for the new locations. We will want to use subnets that reflect our current IP addressing scheme. This will be important to make sure there are connections between hosts and domain controllers as needed. Remote Procedure Calls over Internet Protocol (RPC over IP) is the preferred choice for the replication process. This allows you to communicate with network services on various computers. This will also keep data secure when in transit by using both encryption and authentication. In conclusion this will be a process needing to...
