	RFC 1608 (rfc1608) - Representing IP Information in the X.500 Directory
		IP images of networks As defined in [1], networks are modeled as a set of subnetworks and nodes, called network elements in the remainder.
		Presently, IP network numbers fall into one of the classes A, B, or C. However, sub- and supernetworking is already done broadly, and classless networks numbers are expected to be assigned soon.
		Their purpose is to provide o mapping from IP number to IP network element (network or node) o mapping from IP number to AS number and vice versa o assignment and delegation information The need for a global, distributed database supporting the objectives arises mainly from distributed IP- and AS-number assignment.

	RFC 2322 (rfc2322) - Management of IP numbers by peg-dhcp
		If the network to be numbered is rather large and some kind of subnetting has to be implemented it is possible to give the pegs from the different subnets different colors.
		Transfer of the IP information from the peg and the additional vendorfield paper note to the settings in the IP stack is done by human transfer.
		A certain amount of knowledge of the logic of IP settings is also assumed on the part of the person transferring the information.

		IP Sub-Networking Mini-Howto Robert Hart, hartr@interweft.com.au v1.1, 30 August 2001 This document describes why and how to subnetwork an IP network - that is using a single A, B or C Class network number to function correctly on several interconnected networks.
		Classes of IP Networks There are three classes of IP numbers · Class A IP network numbers use the leftmost 8 bits (the leftmost of the dotted quads) to identify the network, leaving 24 bits (the remaining three dotted quads) to identify host interfaces on that network.
		The network mask for an un-sub-networked IP network number is simply a dotted quad which has all the 'network bits' of the network number set to '1' and all the host bits set to '0'.

	BCR - IP Address FAQ (Site not responding. Last check: 2007-10-30)
		When organizations apply for a domain name (such as bcr.org) they are usually assigned a range of IP numbers that they, in turn, assign to the computers within their domain.
		IP numbers take the form of four groups of a maximum of three digits each (called octets) separated by periods (full stops).
		Instead the firewall or proxy server acts as a forwarding service and attaches a single IP number to the message that is used on all messages from all of the computers behind the firewall or proxy server.

	IP Numbers
		An IP number is a 32-bit binary number, that is, a string of 32 ones and zeros.
		Note that a network number like 199.2.192.64/26 is not by itself an IP number; rather, it defines a range of IP numbers which can be used by hosts on a single network.
		The split between network number and host number can also be represented by a network mask; this is just a number with a '1' in every position of the network part, and a '0' for every bit position of the host part.

	IP Numbers, IP Names, and DNS
		Ranges of IP numbers are assigned to an institution (upon request by the institution, or on the institution's behalf by its ISP) by a national clearinghouse (InterNIC).
		IP numbers are 32 bit numbers, parsed into four sections of eight bits each (each section, separated from the others by a "." is called an "octet.").
		The IP number's hierarchy is the reverse: 123.45.67 describes the institution, while.109 is the lowest domain annotation.

	IP-Adress.com - What is a ip-number? ipnumbers definition
		IP number is the most used alternative word for ip address.
		An IP number can be private, for use on a LAN, or public, for use on the Internet or other WAN.
		IP addresses can be determined statically (assigned to a computer by a system administrator) or dynamically (assigned by another device on the network on demand).

	What is my IP number - MyIpNumber.com
		An IP number (address) is a unique set of numbers assigned to any device that wishes to communicate using the Internet.
		Typically the IP address consists of a set of four numbers in the range 0-255 - the address is usually written as these four numbers separated by dots.
		IP addresses are hierarchical in nature - that is to say, one part of the address will specify broadly in which region of the network the destination can be found, with subsequent parts of the address providing more specific information about the location of the target device within that region.

	TCP/IP Networking and Administration
		IP numbers on a subnet are assigned by the subnet administrator, or block administrator.
		When IP numbers are assigned to machines, the pair of name and number are registered with the domain name server for that domain (forward pointer) and the domain name server for that subnet (reverse pointer).
		The gateway address is the IP number of the gateway (router) that connects your subnet to the rest of the UFNET.

	Viktor's Home Page: An IP Tunnelling Problem
		He is connected to the Internet using a router supplied by his Internet Service provider; the ISP also gave him a set of routable IP numbers in the range of 172.16.1.0-172.16.1.31* (i.e., 172.16.1.0/27), of which the Internet router uses the address 172.16.1.30.
		He bridges these two IP subnets using a Linux machine that has two network cards; one connects the machine to the private network using the IP number 192.168.1.126, while the other connects the machine to the Internet router using the IP number 172.16.1.12.
		IP tunnelling is a method that allows such an IP packet to be encapsulated within another IP packet, this one with a valid destination address; specifically, the external address of the Linux machine on the target network.

	Learn about IP
		The IP address is to the computer as your fingerprint is to you: it is unique, such that there cannot be two computers with the same IP address.
		IP Internet addresses are 32-bit (4 bytes) long logical numbers, normally written as 4 bytes or octets (in decimal form) using the numbers 0 to 255 and separated by periods, e.g.
		The IP information is placed in the header of the data being transferred to ensure correct forward and return data transmission.

	Hello World - Spoofing Techniques
		The fields of the sequence number and acknowledge number in the TCP header are 32 bits wide which means that the maximum value each of them can take is (2^32 - 1) or 4,294,967,295(in decimal).
		It's important for one to understand the procedure of ISN generation because it is highly cohesive with the sequence/acknowledge number prediction when a cracker is forging TCP/IP packets and pretending her machine to be the one the victim trusts.
		Forging her IP address to be the one of the trusted host the cracker sends a request to port 513 of the target machine(three way handshake is initiated with the first TCP segment having SYN flag turned ON).

	IP Tracking - HowTo
		This is convenient when you want to give someone your IP so they can connect to you for downloads, or for you to connect to your home computer to get files when your away.
		To extract the IP number we call 'ipconfig' to display the settings of the adapter on the computer, pipe it to 'find' to extract the line that contains the IP number, then pipe it to 'cut' to get the ip number by itself and dump it into a text file.
		To extract the IP number we use a port of a GNU text-based web browser (lynx) to load the page, pipe the webpage text to 'find' to extract the line containing the IP number, then use 'cut' to get just the IP number and dump it to a text file.

	IP Numbers
		An IP number is a 32-bit binary number, that is, a string of 32 ones and zeros.
		For IP routing to work, it is vital that all hosts on one network have the same network number (in this example, the left-hand 26 bits), and different host numbers.
		Note that a network number like 199.2.192.64/26 is not by itself an IP number; rather, it defines a range of IP numbers which can be used by hosts on a single network.

	Sangoma - TCP/IP Tutorial
		An IP address is 32 bits wide, and as discussed, it is composed of two parts: the network number, and the host number [1, 2, 3].
		By convention, it is expressed as four decimal numbers separated by periods, such as "200.1.2.3" representing the decimal value of each of the four bytes.
		This way, A knows from C's IP address that it is on its own network, and similarly for E. Within C, the routing module will know from the network number of each interface which one to use for forwarding IP packets.

		The demand for network numbers has grown significantly within the last two years and as a result the allocation of network numbers must be approached in a more systematic fashion.
		Small blocks of numbers may be allocated to regional registries, which will be required to ensure that the allocation guidelines are met.
		Due to the scarcity of Class B network numbers and the underutilization of the Class B number space by most organizations, the recommendation is now to use multiple Class Cs where practical.

		This option is a strict source route because the gateway or host IP must send the datagram directly to the next address in the source route through only the directly connected network indicated in the next address to reach the next gateway or host specified in the route.
		The Pointer is the number of octets from the beginning of this option to the end of timestamps plus one (i.e., it points to the octet beginning the space for next timestamp).
		The Overflow (oflw) [4 bits] is the number of IP modules that cannot register timestamps due to lack of space.

	Internet Protocol (IP) Addresses
		The IP address is the geographical descriptor of the virtual world, and the addresses of both source and destination systems are stored in the header of every packet that flows across the Internet.
		An IP address is made up of four bytes of information (totaling 32 bits) expressed as four numbers between 0 and 255 shown separated by periods.
		The historical top-level allocations of these blocks of IP addresses are described in Request For Comments 1466.

	What is static IP address/dynamic IP address? - a definition from Whatis.com - see also: static IP address, dynamic IP ...
		A static IP address is a number (in the form of a dotted quad) that is assigned to a computer by an Internet service provider (ISP) to be its permanent address on the Internet.
		Computers use IP addresses to locate and talk to each other on the Internet, much the same way people use phone numbers to locate and talk to one another on the telephone.
		To get around that problem, many Internet service providers limit the number of static IP addresses they allocate, and economize on the remaining number of IP addresses they possess by temporarily assigning an IP address to a requesting Dynamic Host Configuration Protocol (DHCP) computer from a pool of IP addresses.

	What is IP address? - a definition from Whatis.com
		An IP address has two parts: the identifier of a particular network on the Internet and an identifier of the particular device (which can be a server or a workstation) within that network.
		The number version of the IP address can (and usually is) represented by a name or series of names called the domain name.
		However, a new IP version, IPv6, expands the size of the IP address to 128 bits, which will accommodate a large growth in the number of network addresses.

		IP Header (Numbers represent bits of data from 0 to 32 and the relative position of the fields in the datagram)
		Methods that incorporate a random number generation of the sequence number with a subsequent inclusion of the data to be encoded through an XOR or similar operation may yield a more random result.
		This method would leave the sequence numbers intact and would allow for a drawn out communication session where error correction and flow control are still handled by the IP and TCP layers and the remote system can re-send packets if corrupted with information again imbedded in the header.
