	Howstuffworks "What is an IP address?"
		For example, the IP address 0.0.0.0 is reserved for the default network and the address 255.255.255.255 is used for broadcasts.
		IP addresses with a first octet from 128 to 191 are part of this class.
		IP addresses with a first octet from 192 to 223 are part of this class.

	IP 101: All About IP Addresses
		IP addresses most commonly come as class A, B, or C. It's the value of the first number of the IP address that determines the class to which a given IP address belongs.
		From this IP address and subnet mask, the network number is derived by the IP stack and tracked in the routing table.
		IP addresses are used to deliver packets of data across a network and have what is termed end-to-end significance.

	IP address - Wikipedia, the free encyclopedia
		An IP address can also be thought of as the equivalent of a street address or a phone number (compare: VoIP) for a computer or other network device on the internet.
		IP addresses may either be assigned permanently (for example, to a server which is always found at the same address) or temporarily from a pool of available addresses.
		Dynamic IP addresses are issued to identify non-permanent devices such as personal computers or clients.

	Internet Protocol - Wikipedia, the free encyclopedia
		This resolving is addressed by the Address Resolution Protocol (ARP).
		Addressing refers to how end hosts become assigned IP addresses and how subnetworks of IP host addresses are divided and grouped together.
		IP routing is performed by all hosts, but most importantly by internetwork routers, which typically use either interior gateway protocols (IGPs) or external gateway protocols (EGPs) to help make IP datagram forwarding decisions across IP connected networks.

	The IP Address
		Addresses in other places than computer networks: Addresses are used by the postal system to allow a postman to find a person's house; to allow a computer to uniquely identify a location in memory.
		Each IP address consists of two parts, the network part (identifying the network number, or LAN broadcast domain, to which the computer is attached) and the host part (which identifies the host within the local network).
		An IP address may be unicast (for a specific end system), network broadcast (for all systems on a LAN) or multicast (for a group of end systems).

	IP Address Spoofing
		IP address spoofing is possible because the network devices that provide connectivity between individual networks, called routers, only require inspection of the destination IP address in the packet to make routing decisions.
		IP is a network layer protocol that is used to deliver packets across connected networks to their intended destination.
		Further inspection of the colored packet reveals that the destination IP address of 24.12.36.5 is a valid IP address within Network B. The source IP address of 121.34.5.171 is not part of the valid IP address range of Network A.

	IP Address's (Site not responding. Last check: 2007-11-07)
		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.
		Addresses beginning with 01111111, or 127 decimal, are reserved for loop back and for internal testing on a local machine.
		In the example, 140.179.220.200 is a Class B address so by default the Network part of the address (also known as the Network Address) is defined by the first two octets (140.179.x.x) and the node part is defined by the last 2 octets (x.x.220.200).

	IP Addresses
		The subnet mask specifies which portion of the IP address is the network number and which portion is the host ID. This mask is the same for all nodes on a given LS2020 network.
		The subnet mask for the NP's Ethernet address specifies which portion of the IP address is the network number and which portion is the host ID. This mask is the same for all nodes on the Ethernet LAN attached to the primary NP.
		This IP address has the network number for the attached Ethernet LAN (which must be different from the network number of the LS2020 network), plus a host number that is assigned by the network administrator of the Ethernet LAN.

	How do I find out my IP address? (Site not responding. Last check: 2007-11-07)
		On many networks, the IP address of a computer is always the same.
		On other networks, a random IP address is assigned each time a computer connects to the network.
		In this case, the IP address of your machine as reported by your TCP/IP settings is not reachable from outside your network.

	IP Address
		Just as your postal address enables the postal system to send mail to your house from anywhere around the world, your computer's IP address gives the Internet routing protocols the unique information they need to route packets of information to your desktop from anywhere across the Internet.
		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.

	What is IP address? - a definition from Whatis.com
		In the most widely installed level of the Internet Protocol (IP) today, an IP address is a 32-bit number that identifies each sender or receiver of information that is sent in packets across the Internet.
		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.

	Internet Protocols (IP)
		IP addressing supports five different address classes: A, B,C, D, and E. Only classes A, B, and C are available for commercial use.
		illustrates that when a logical AND of the destination IP address and the subnet mask is performed, the subnetwork number remains, which the router uses to forward the packet.
		In addition to the Reverse Address Resolution Protocol (RARP) is used to map MAC-layer addresses to IP addresses.

	Geolocation by IP Address \| Linux Journal
		Geolocation by IP address is the technique of determining a user's geographic latitude, longitude and, by inference, city, region and nation by comparing the user's public Internet IP address with known locations of other electronically neighboring servers and routers.
		Dial-up, cable modems and cell phone connections are assigned a dynamic IP address that may change multiple times in one day or not at all for several weeks.
		I realize that while within one's own geographical confines, this IP binding practice may be beneficial, it is detrimental to the point of driving the end user insane outside of his or her native geographical region.

	InetAddress (Java 2 Platform SE 5.0)
		An IP address is either a 32-bit or 128-bit unsigned number used by IP, a lower-level protocol on which protocols like UDP and TCP are built.
		An instance of an InetAddress consists of an IP address and possibly its corresponding host name (depending on whether it is constructed with a host name or whether it has already done reverse host name resolution).
		The textual representation of an IP address is address family specific.

		Networks using the TCP/IP protocol route messages based on the IP address of the destination.
		Within an isolated network, you can assign IP addresses at random as long as each one is unique.
		The number of unassigned Internet addresses is running out, so a new classless scheme called CIDR is gradually replacing the system based on classes A, B, and C and is tied to adoption of IPv6.

		Various Aspects of NAT 3.1 Address Spaces Partitioning of Reusable and Non-reusable Addresses For NAT to operate properly, it is necessary to partition the IP address space into two parts - the reusable addresses used internal to stub domains, and the globally unique addresses.
		Say a host in stub A wished to send packets to a host in stub B, but the local addresses of stub B overlapped the local addressees of stub A. In this case, the routers in stub A would not be able to distinguish the global address of stub B from its own local addresses.
		Because the address is encoded in ASCII, this may result in a change in the size of the packet (for instance 10.18.177.42 is 12 ASCII characters, while 193.45.228.137 is 14 ASCII characters).

	Webopedia: Understanding IP Addressing
		An IP address consists of 32 bits, often shown as 4 octets of numbers from 0-255 represented in decimal form instead of binary form.
		An example of a Class A IP address is 102.168.212.226, where "102" identifies the network and "168.212.226" identifies the host on that network.
		An example of a Class C IP address is 200.168.212.226 where "200.168.212" identifies the network and "226" identifies the host on that network.

	IP Address Classes
		On the other hand, a binary IP address of 00000000.00000000.00000000.00000000 will be, in decimal, 0.0.0.0, which in a routing table represents an unknown network or host, and is typically used to designate the default gateway of last resort.
		Generally, there will be only as many IP addresses as may be designated by the three most common classes of IP addresses, A, B and C. There are two more classes, D and E, but they are used for multicast and experimental purposes respectively, so we won't get into those here.
		The default subnet mask for a Class A IP address is 255.0.0.0; Class B is 255.255.0.0 and Class C is 255.255.255.0.

	Find out your computer's IP address
		Do you know what your computer's IP address is? For example, knowing your IP address could help you to remove hits to your web page counter from your computer, so that it will not increment while you view or edit your own pages.
		Note that seeing the same IP address after reconnecting does not necessarily mean that you have a static IP address.
		If you have a dynamic IP address and feel that excluding 255 addresses, for example, from millions of addresses on the Internet is significant, your ISP may be able to provide you with a static IP address for a small fee, even if you're using a dial-up connection.

	IP Address (Site not responding. Last check: 2007-11-07)
		A basic concept of IP addressing is that initial prefixes of the IP address can be used for generalized routing decisions.
		IP addresses are assigned on a per-interface basis, so a host might possess several IP addresses if it has several interfaces.
		Dynamically addressed hosts use management protocols to obtain their IP addresses from a server; most statically addressed hosts are manually configured with their IP address.

	IP Address
		This address is like a telephone number, but one which can typically change [unless you subscribe for a static IP service] every time you dial up, or every time you power cycle your modem or router.
		I like to divide the types of IP addresses into three types, public, private, and "illegal." "Public" IP addresses are those which are accessible on the Internet.
		If I know the IP address of Joe in CA, which I get by using the DNS service, then I just send the packet to my gateway, who forwards it on into the Internet routers, who have the collective knowledge to get the packet to Joe in CA.
