...12.5% (or 1/8th) of the total IPv4 unicast address space. Class D Class D addresses have their leading four-bits set to 1-1-1-0 and are used to support IP Multicasting (IP Address, 2010). RFC 1918 IP address ranges There are 3 IP ranges that are not routed across the Internet and can only be used on local networks. These are RFC 1918 IP addresses. You will sometimes see these used on ISP networks, where the devices can only be accessed from within the ISP's network, not from the rest of the Internet. There are 3 IP ranges defined in RFC 1918: (, (, ( (havoc, 2012) Sampling of Martian/ Bogon address ranges A bogon list is a compilation of address ranges that are used on private networks and should not be visible on the public Internet under normal operation. Some bogons do appear on the public Internet for various reasons, including the (legitimate) use of non-globally unique addresses for router interfaces, source address spoofing in DDoS attacks and the use of unallocated address blocks for malicious or fraudulent purposes (Hyan, 2004) Martians A Martian packet is a packet that is reserved for special use by (IANA) and can’t actually be used or delivered.

...IP networking 12/17/2013 IP Addresses Classes and specific-Use IP Address Space An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication.[1] An IP address serves two principal functions: host or network interface identification and location addressing. Its role has been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there."[2] The designers of the Internet Protocol defined an IP address as a 32-bit number[1] and this system, known as Internet Protocol Version 4 (IPv4), is still in use today. However, due to the enormous growth of the Internet and the predicted depletion of available addresses, a new version of IP (IPv6), using 128 bits for the address, was developed in 1995.[3] IPv6 was standardized as RFC 2460 in 1998,[4] and its deployment has been ongoing since the mid-2000s. IP addresses are binary numbers, but they are usually stored in text files and displayed in human-readable notations, such as (for IPv4), and 2001:db8:0:1234:0:567:8:1 (for IPv6). The Internet Assigned Numbers Authority (IANA) manages the IP address space allocations globally and delegates five regional Internet registries (RIRs) to allocate IP address blocks to local Internet registries (Internet service providers) and other entities. In IPv4 an address consists......

Ip Subnetting

...n IP (Internet Protocol) address is a unique identifier for a node or host connection on an IP network. An IP address is a 32 bit binary number usually represented as 4 decimal values, each representing 8 bits, in the range 0 to 255 (known as octets) separated by decimal points. This is known as "dotted decimal" notation. Example: It is sometimes useful to view the values in their binary form. 140 .179 .220 .200 10001100.10110011.11011100.11001000 Every IP address consists of two parts, one identifying the network and one identifying the node. The Class of the address and the subnet mask determine which part belongs to the network address and which part belongs to the node address. Address Classes There are 5 different address classes. You can determine which class any IP address is in by examining the first 4 bits of the IP address. Class A addresses begin with 0xxx, or 1 to 126 decimal. Class B addresses begin with 10xx, or 128 to 191 decimal. Class C addresses begin with 110x, or 192 to 223 decimal. Class D addresses begin with 1110, or 224 to 239 decimal. Class E addresses begin with 1111, or 240 to 254 decimal. Addresses beginning with 01111111, or 127 decimal, are reserved for loopback and for internal testing on a local machine; [You can test this: you should always be able to ping, which points to yourself] Class D addresses are reserved for multicasting; Class E addresses are reserved for future use.

Nasty Nas

...Nafees Bost Professor Jordan-smith English 112 15 April 2013 Nasty Nas Quite possibly the only man to indirectly steal my attention with sheer words alone, such a man would have to be non-other than Nas, or Nasir bin Olu Dara Jones. Born the son of jazz musician Olu Dara, Nas dropped out of school in the eighth grade, trading classrooms for the streets of the rough Queensbridge projects, long fabled as the former stomping ground of Marley Marl and his Juice Crew as immortalized in "The Bridge." Despite having dropped out of school in the eighth grade, Nas developed a high degree of literacy that would later characterize his rhymes. At the same time, though, he delved into street culture and flirted with danger, such experiences similarly characterizing his rhymes. His synthesis of well-crafted rhetoric and street-glamorous imagery blossomed in 1991 when he connected with Main Source and laid down a fiery verse on "Live at the Barbeque" in which earned him instant respect among the East Coast rap scene. Not long afterward, MC Serch of 3rd Bass approached Nas about contributing a track to the Zebrahead soundtrack. Serch had been the soundtrack's executive producer and, like much of New York, had been impressed by "Live at the Barbeque." Nas then submitted "Halftime," and the song had impressed Serch enough for him to make it the soundtrack's leadoff track. Columbia Records meanwhile signed Nas to a major-label contract, and many of New York's finest producers......

History. 3. Product demonstration. 4. NAS future perspective. 5. Introduction Network Attached Storage is basically defined as a file level computer data storage server connected to a computer network. It is specialized for file server operation by its hardware, software or configuration of elements to provide data access to wide range of clients (Wikipedia, 2014). In simple words we can say “a network attached storage is a external hard drive which is a computer storage system that access and remains on a computer network via Ethernet and wireless connections. The drive is then accessible to all computers in a network, instead of one just hard wired computer”(Networking, 2014). Figure-1: NAS Storage on a network infrastructure. (slideshare, 2013). NAS is one of the popular approaches which allow homes and business to store and retrieve large amounts of data in an efficient and affordable manner. One can wirelessly backup their computer files such as music, videos and other important documents onto NAS and share the files seamlessly with any connected device such a home theatre and smart TV’s.(Networking, 2014).

Nas Devices

...Structure and Logic Research Project – Network Attached Storage A Network Attached Storage (NAS) device is a device connected to a network of two or more computer with the purposes of providing “community storage” of files and other data. As our society moves closer towards greater mobility the need to have mobile storage has increased. There are many types of storage devices, with various advantages and disadvantages to each of them; including Direct Attached Storage (DAS) and Network Attached Storage Devices. NAS devices are useful if all the computers on the network need access to the same files, DAS can only be accessed by the computer they are attached to (unless the computer grants access to another user. Most NAS devices contain multiple hard drives, which are connected by an internal server. There are many features of NAS devices. The speed of the network is dependent on the service available to the network and the number of users on the network. The capacity range of the network is depend on the hard drives contained in the device and the way it is setup. As with most servers or combination of two or more hard drives (Redundant Array of Independent Disks) RAID can be set up to maximize the use of the server and to protect the data. Also most NAS devices have software, which can be installed on client computers which allows the user to manage the device. The device has an IP address which also allows you to manage the device and connect to it. Password,......

Ip Spoofing

...IP Spoofing: An Introduction Criminals have long employed the tactic of masking their true identity, from disguises to aliases to caller-id blocking. It should come as no surprise then, that criminals who conduct their nefarious activities on networks and computers should employ such techniques. IP spoofing is one of the most common forms of on-line camouflage. In IP spoofing, an attacker gains unauthorized access to a computer or a network by making it appear that a malicious message has come from a trusted machine by “spoofing” the IP address of that machine. In this article, we will examine the concepts of IP spoofing: why it is possible, how it works, what it is used for and how to defend against it.Internet Protocol – IP Internet protocol (IP) is a network protocol operating at layer 3 (network) of the OSI model. It is a connectionless model, meaning there is no information regarding transaction state, which is used to route packets on a network. Additionally, there is no method in place to ensure that a packet is properly delivered to the destination.Examining the IP header, we can see that the first 12 bytes (or the top 3 rows of the header) contain various information about the packet. The next 8 bytes (the next 2 rows), however, contains the source and destination IP addresses. Using one of several tools, an attacker can easily modify these addresses – specifically the “source address” field. It's important to note that each datagram is sent independent of all......

When you request an HTML page or send e-mail, the Internet Protocol part of TCP/IP includes your IP address in the message (actually, in each of the packets if more than one is required) and sends it to the IP address that is obtained by looking up the domain name in the Uniform Resource Locator you requested or in the e-mail address you're sending a note to.
