About this product: An Internet Protocol (IP) address is a numerical label that is assigned to devices participating in a computer network utilizing the Internet Protocol for communication between its nodes. An IP address serves two principal functions in networking: host or network interface identification and location addressing. The role of the IP address has also been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there." The original designers of TCP/IP defined an IP address as a 32-bit number and this system, known as Internet Protocol Version 4 or IPv4, is still in use today. However, due to the enormous growth of the Internet and the resulting depletion of available addresses, a new addressing system (IPv6), using 128 bits for the address, was developed in 1995 and last standardized by RFC 2460 in 1998
About this product: The practice of IP address managment encompasses three very complex IP networking functions: IP subnetting and address assignment, DNS services configuration and management, and DHCP service configuration and management. This is the first book to unify these three topics. It describes these services in detail and illustrates their interdependencies and management techniques. It also discusses the relevant protocols, configuration details for market-leading reference implementations from Microsoft and the Internet Systems Consortium (ISC), and techniques that can be employed to structure, monitor, secure and manage them. This book will educate readers responsible for managing IP address space and DHCP and DNS server configurations.
About this product: Just as telephone area codes can no longer hold the growing volume of numbers needed, networks are becoming too crowded with IP addresses. This has now become one of the top five strategic issues for systems administratators who have to renumber IP addresses as networks grow and change. Administrators responsible for network design need to anticipate periodic renumbering and constantly re-evaluate the network's abilitity to be changed easily. There are many reasons to renumber including: internal reorganisation, mergers and spin-offs, major technical change in a network, and users and ISPs changing service provider. This text tells how, when and why to renumber a network and provides the tips and techniques needed to get through the project. Following these guidelines, the project can be easier, more cost effective, and transparent to the end-user. Among the topics covered are: planning and designing the network; practical advice on creating IP addresses (numbering); coping techniques for network growth and reorganisation, including Network Address Translation (NAT); and model case studies.
About this product: High Quality Content by WIKIPEDIA articles! In the Internet addressing architecture, a private network is a network that uses private IP address space, following the standards set by RFC 1918 and RFC 4193. These addresses are commonly used for home, office, and enterprise local area networks (LANs), when globally routable addresses are not mandatory, or are not available for the intended network applications. Private IP address spaces were originally defined in an effort to delay IPv4 address exhaustion, but they are also a feature of the next generation Internet Protocol, IPv6. These addresses are characterized as private because they are not globally delegated, meaning they are not allocated to any specific organization, and IP packets addressed by them cannot be transmitted onto the public Internet. Anyone may use these addresses without approval from a regional Internet registry (RIR). If such a private network needs to connect to the Internet, it must use either a network address translator (NAT) gateway, or a proxy server.
About this product: An Intrusion prevention system (IPS) is a network security device that monitors network and/or system activities for malicious or unwanted behavior and can react, in real-time, to block or prevent those activities. Network-based IPS, for example, will operate in-line to monitor all network traffic for malicious code or attacks . When an attack is detected, it can drop the offending packets while still allowing all other traffic to pass. Intrusion prevention technology is considered by some to be an extension of intrusion detection (IDS) technology . Intrusion prevention systems evolved in the late 1990s to resolve ambiguities in passive network monitoring by placing detection systems in-line. Early IPS were IDS that were able to implement prevention commands to firewalls and access control changes to routers.
About this product: High Quality Content by WIKIPEDIA articles! The Network Layer is Layer 3 of the seven-layer OSI model of computer networking.The Network Layer is responsible for end-to-end (source to destination) packet delivery including routing through intermediate hosts, whereas the Data Link Layer is responsible for node-to-node (hop-to-hop) frame delivery on the same link.The Network Layer provides the functional and procedural means of transferring variable length data sequences from a source to a destination host via one or more networks while maintaining the quality of service and error control functions.
About this product: High Quality Content by WIKIPEDIA articles! Supranet is a term coined at the turn of the century by information technology analysis firm Gartner to describe the fusion of the physical and the digital (?virtual?) worlds. At its inception, the term was alluding to the ongoing convergence of the internet, mobile communications, always-on connectivity, sensors and advanced human-computer interaction. In subsequent elaborations, it was extended to include electronic tagging (via, e.g., RFID), geotagging and electronic geomapping (i.e., mapping internet coordinates to geodetic coordinates), thereby completing the fusion of physical and virtual. (The first Gartner analyst to use the term Supranet might have been Geoff Johnson, who is also quoted using it in Computerworld, by Sue Bushell on July 24, 2000, in ?M-commerce key to ubiquitous internet?)
About this product: High Quality Content by WIKIPEDIA articles! An overlay network is a computer network which is built on top of another network. Nodes in the overlay can be thought of as being connected by virtual or logical links, each of which corresponds to a path, perhaps through many physical links, in the underlying network. For example, many peer-to-peer networks are overlay networks because they run on top of the Internet. Dial-up Internet is an overlay upon the telephone network.
