This serves a parent to child relationship with the two trees: Company Beta‚ U.S.A (usa.companybeta.com in Boston) and Company Beta‚ Canada (canada.companybeta.com‚ in Toronto). These two tree roots in turn serve parent to child relations with their respective subdomains residing in the separate cities. Since subnets are basically

addresses. A great example of what this may look like is that the IP address is written in some type of a dot formatted number called subnet masking. The biggest one known is the normal dot decimal for example‚ 192.3.0.233. To better understand subnet masking it must be first understood that IP address is in series of four eight-bit numbers which is a 32 bit combined. Subnet mask is a series of numbers followed by 0 for example‚ 255.255.255.0. These types of addresses have nearly 300 million different

Q1: If an Ethernet port on router was assigned an IP address of 172.16.112.1/20‚ what is the maximum number of hosts allowed on this subnet? A. 1024 B. 2046 C. 4094 D. 4096 E. 8190 Answer: C Explanation: Given IP address of 172.16.112.1 / 20‚ subnet mask: 255.255.240.0 max. num of hosts =(( 2^12) -2 ) = 4096-2 = 4094 Q2.:An access list was written with the four statements shown in the graphic. Which single access list statement will combine all four of these statements into a single statements that

TCP/IP for IP version 4 (IPv4) is a networking protocol suite that Microsoft Windows uses to communicate over the internet with other computers. It interacts with Windows naming services like DNS and security technologies‚ such as IPsec primarily‚ as these help facilitate the successful and secure transfer of IP packets between machines. Ideally‚ TCP/IP is used whenever Windows-based computers communicate over networks. This subject describes the components of the TCP/IP Protocol Suite‚ the protocol

VLSM (Variable Length Subnet Mask) When we perform Subnetting most of the time each subnet has the same number of available host addresses. You can need this in some cases‚ but‚ in most cases‚ having the same subnet mask for all subnets ends up wasting address space. In this situation VLSM is used. During this method the subnets are of variable length‚ depending

INTRODUCTION Computer networking is the engineering discipline concerned with the communication between computer systems or devices. A computer network is any set of computers or devices connected to each other with the ability to exchange data. It is sometimes considered a sub-discipline of telecommunications‚ computer science‚ information technology and computer engineering since it relies heavily upon the theoretical and practical application of these scientific and engineering disciplines

numerical label called an IP (Internet Protocol) Address is assigned. There are two functions of an IP Address a host or network interface identification‚ and also provides a location addressing. The basic elements of a network are the IP Address and Subnet Mask. There is also switching and routing which after you connect devices to switches and routers‚ data packets can be moved across the network. The Internet Protocol Version 4 (known as IPv4) is a protocol highly used even today‚ this IP Address

If the DHCP server is not present on the local subnet‚ a DHCP discovery must be forwarded by the router. And this is done by configuring an IP Helper Address on the router‚ to relay certain broadcast UDP frames (like DHCP) to a specific IP destination. In case of DHCP - the router will forward the DHCP

These aspects include the type of domain model used for current domain model‚ the affects subnets may or may not have‚ how a new domain model can provide better security‚ how to improve the domain name system‚ the Internet domain name and its effect on the DNS name-resolution process‚ and can ISDN be improved. In addition‚ it will also be noted
