Abstract- The paper discusses security issues with Dynamic Host Configuration Protocol (DHCP) and four different approaches proposed to secure DHCP. DHCP assigns network parameters to existing and new clients. A misconfigured client is a big security breach as the traffic from and to such client can be intercepted. The two main issues with DHCP are rogue server and Media Access Control (MAC) address spoofing. The techniques discussed in the paper attempt at solving these problems by encrypting the

DHCP Dynamic Host Configuration Protocol (DHCP), allows a computer to join a network without a statically assigned Internet Protocol (IP) address (Mitchell, n.d., para 1). With DHCP a device can be assigned a unique IP address, as it joins the network (Mitchell, n.d., para 1). DHCP is done on a server, and parameters are set on the pool of IP addresses that can be assigned (Mitchell, n.d., para 4). In Server 2012 there are options to allow for fault-tolerance for DHCP. The three options available

Fundamentals of Networking IT204 Discussion Board 4 9/8/2017 Static IP address is an IP address that is permanent to a specific host for a certain amount of time. This IP address is assigned by the ISP out of a specific designated block of IP addresses and manually entered into the computer. While primarily IP addresses are sent to the host by the DHCP now, certain people prefer static IP. Static IP is also used for the URL or uniform resource locator to give a website

The Dynamic Host Configuration Protocol (or DHCP) is intended to make the life of the network administrator easier by assigning IP addresses to the computers on the company’s network. DHCP not only automatically assigns IP addresses to the computers, but it also leases, reserves, and excludes IP addresses to the computers. The process of installing and configuring DHCP is not difficult, but you must be careful when you set the scope the scope if you want to avoid any problems in the future. To successfully

9.1 DHCP SNOOPING What Is DHCP? Hosts communicate with each other through addressing in a network. At first devices used to be assigned unique static IP addresses. But, this system could not be scaled up when mobile devices became more common. Modifying each device’s address, such as that of a mobile phone or laptop, each time it moved from one location to another became very complex. To resolve this issue, dynamic address configuration was developed, and soon became the standard addressing system

IT PROPOSAL FOR THE KRIS COPORATION2 Information Technology Proposal Active Directory Migrating to 2012 AD Different companies or organizations have different reasons and ways of migrating to Windows 2012 Active Directory. Some of the reasons as to why the company needs to migrate to 2012 Ad include freedom of interface choice whereby there is a wide variety of interface choice that can be accessed through 2012 AD (Taft, 2012). The other reasons as to why the company needs 2012 AD include

My boss asked me to come up with a proposal to migrate Windows XP machines to Linux. The company Linx LLC has a new research and development group – LSDG. All systems in LSDG will be running Linux and will access and share resources with Linx LLC. The company has around 500 client operating system desktop/laptops that runs Windows 7 and Windows XP. LSDG needs to decide whether they’re going to keep using both Windows XP and Windows 7 on their desktops and laptops. LSDG must consider the following:

One of the branch offices is ver small (5 users) and has very slow network connectivity. Do I need a DNS Server and if so, which type of zone should it host? The second branch office is much larger (about 30 users) and has better network connectivity. Does this office need a DNS Server and if so, what type of zone would you recommend? Dear Junior Admin: Most often, you will install DNS servers on

services in a Graphical based, Windows environment. • The Domain Name System/Service offers the ability to translate IP addresses into easy to remember canonical names. It is recursive and highly available. • The Dynamic Host Control Protocol automatically assigns IP addresses to hosts on a network as they request them. DHCP packets also include information like DNS server addresses, domain names, and default gateways. • Active Directory is responsible for assigning and enforcing security policies
