...legitimate device and not an attacker impersonating a legitimate device. Cost savings - VPNs enable organizations to use the global Internet to connect remote offices and remote users to the main corporate site, thus eliminating expensive, dedicated WAN links and modem banks. Security - VPNs provide the highest level of security by using advanced encryption and advanced authentication protocols that protect data from unauthorized access. Scalability - Because VPNs use the Internet infrastructure within ISPs and devices, it is easy to add new users. Corporations are able to add large amounts of capacit without capacity adding significant infrastructure. Prepared by: Md. Azaj Ikbal (RHCE, CCNA, CEH). CSL Training. All rights are reserved.

...Subnetting Made Simple IP Subnetting without Tables, Tools, or Tribulations Larry Newcomer The Pennsylvania State University York Campus Abstract Every networking professional should have a thorough understanding of TCP/IP subnetting. Subnetting can improve network performance by splitting up collision and broadcast domains. Subnets can reflect organizational structure and help support security policies. WAN links typically join different subnets. Subnets can define administrative units and hence support the structuring and delegation of administrative tasks. Unfortunately, mastering subnetting can pose difficulties for both professionals and students because of the binary mathematics that underlies the technology. While it is imperative to present subnetting concepts in terms of the underlying binary representation, most texts also present subnetting procedures in binary terms. Such an approach can make it difficult for students to learn how to actually carry out subnetting without tables or other reference materials, even when they understand the basic concepts. This paper presents a simple, alternative method for understanding and implementing subnetting without software, calculators, tables, or other aids. The only knowledge of binary arithmetic required is familiarity with the powers of 2 from 0 to 8 (2x for x = 0, 1, …, 8). With a little decimal arithmetic thrown in, the whole process is simple enough to be carried out mentally. This paper assumes the reader...

Before that can happen, the department’s budgets must be adjusted and new hardware needs to be purchased for new employees. ABC will required to choose the type network they will use and what kind network devices it will need. Each internal and external networking component will you give information on what needs to be connected from inside and outside from your computer. Security must be carefully handle firewalls and vpns must be secured for your network to be secured from hackers and that your data protectect from any kind attack. When it comes choosing which network you will need, local area network (LAN) is office environment network. LAN network consists sharing resources, for your company files and printers. Usually LAN network not expensive and can be build with not expensive components.LAN network has big adavantage to hold thousands users with wired connection which can also include wireless connection for users who travel and need wireless connection. The internal and external networking components are important, so company computers can work properly on the network. Internal components can include Intel wireless LAN card which gives you ability getting connected to network wirelessly and PCI Ethernet card gives you ability getting to internet through network cable.

Once that is done named the server (mailitsupport.com), set the clock and it’s configured to be a stand alone with default settings. Configure Your Static IP Address The default installation of Windows 2008 sets your IP v4 and IP v6 addresses to use DHCP.

In this lab, you create and execute a Tcl script that sends pings to multiple IP addresses in the network to test overall network connectivity. Note: Cisco IOS Release 12.3(2)T and later supports Tcl scripting. Required Resources • • 2 routers (Cisco 1841 with Cisco IOS Release 12.4(24)T1 Advanced IP Service or comparable) Serial and console cables Note: This lab uses Cisco 1841 routers with Cisco IOS Release 12.4(24)T1 and the advanced IP image c1841-advipservicesk9-mz.124-24.T1.bin. Other routers (such as a 2801 or 2811) and Cisco IOS Software versions can be used if they have comparable capabilities and features.

...Checkpoint: TCP/IP LAN Plan 1. An IPv6 address is made up of how many bits? a. 32 b. 48 c. 64 d. 128 e. 256 The answer to this question is d. Ipv6 address has 128 bits which is better than Ipv4 which has only 32 bit addresses. If I understand it with Ipv4 the amount of addresses will soon run out. With Ipv6 as stated in the book unless every star in the universe were assigned an address it is unlikely to run out of addresses. With Ipv4 it was stated that there are only 4 billion possible addresses. With Ipv6 there are 3.4x10^38 or 34 followed by 37 zeroes. Ipv6 resolves some problems found in Ipv4 such as limited addresses, security, sometimes complicated setup and quality of service (QoS). QoS describes the ability of a network to prioritize data packets based on the type of information. Ipv6 makes the handling of special packets easier to implement, such as applications that use video or audio. Whereas Ipv4 uses a dotted decimal in 8 bit sections, Ipv6 uses a hexadecimal format in 16 bit sections. At first I was a bit confused over what this meant and looking at the address example further confused me. Then after further reading I discovered that each 16 bit section was ended with a colon. It was explained that there are three sections to the address they are public topology, a site topology, and an interface identifier. If I am right then the address giving in the book would break down like this: 2001:DB8:0:0:0:2ed3:340:ab The first 3 16 bit sections 2001:DB8:0: represent...
