refimprove date April 2010 Virtual IPaddress VIP or VIPA is an IPaddress assigned to multiple domain names, servers or applications residing on a single server instead of connected to a specific server or network card network interface card NIC on a server. Incoming data packets are sent to the VIP address which are routed to actual network interfaces. A server IPaddress depends on the Media Access Control MAC address of the attached NIC, and only one logical IPaddress may be assigned per card. However, VIP addressing enables hosting for several different applications and virtual appliances on a server with only one logical IPaddress. VIP have several variations and implementation scenarios, including Common Address Redundancy Protocol CARP and Proxy ARP Proxy Address Resolution Protocol Proxy ARP . Usage VIPs are mostly used to consolidate resources through the allocation of one network interface per hosted application. It is also used for connection redundancy by providing alternative fail over options on one machine A VIP address may still be available if a computer or NIC fails, because an alternative computer or NIC replies to connections. ref http www.webopedia.com TERM v virtual IP address.htm What is virtual IPaddress?

The gateway has both a physical and logical address. Logical Gateway Address The gateway operates at the Computer network Network layer Layer 3 of the OSI ... network as the end devices. The gateway address must have the same Subnet Mask as the host devices. Each host on the network uses the same gateway. The gateway should have a static address as changing the address would cause packets to not be delivered. The gateway is typically assigned either the highest or lowest address on the network. This is not a requirement, but many organizations use a consistent addressing scheme to make network planning easier. Physical Gateway Address The gateway also operates at the Data Link layer Layer 2 of the OSI Network Model. The physical gateway address is known as the Media Access Control MAC address or Burned In Address BIA . The physical address ... is being sent to a device that is not on the local network, the gateway s MAC address is used in the Frame networking Frame Header. Proxy ARP If a network device is looking for an address outside of the local network, it will send an Address Resolution Protocol ARP Request. Since the destination ... more details
Multiple issues wikify December 2009 unreferenced August 2010 peacock August 2011 Flat IP architecture provides a way to identify devices using symbolic names, unlike the hierarchy hierarchical architecture such as that used in normal IPaddress es. This form of system is of more interest to mobile broadband network operators. Flat IP architectures in mobile networks From 3G to LTE Wireless networks are defined in terms of generations of radio technology and how over the air data rates affect and enable ... wired network elements radio controllers, packet gateways, transmission, and the IP core ..., and greater flexibility.

IP traceback is a name given to any method for reliably determining the origin of a packet information technology packet on the Internet. Due to the trusting nature of the Internet Protocol IP protocol, the source IPaddress of a packet is not authenticated. As a result, the source address in an IP packet can be falsified IPaddress spoofing allowing for Denial of service Denial Of Service attacks .... They propose that the router mark the packet with either the router s IPaddress or the edges ... packets with the router s IPaddress, analysis shows that in order to gain the correct attack path with 95 ... forming an edge in the path with each other. Node a inserts its IPaddress into the packet and sends it to b . Upon being detected at b by detecting a 0 in the distance , b XORs its address with the address ... scheme instead of encoding the IPaddress interleaved with a hash, they suggest encoding the IPaddress into an 11 bit hash and maintain a 5 bit hop count, both stored in the 16 bit fragment ID field ..., it generates an 11 bit hash of its own IPaddress and then XORs it with the previous hop. If it finds a non zero hop count it inserts its IP hash, sets the hop count to zero and forwards ... half of the IPaddress of the ingress interface into the fragment id field of the packet, and then set ... in that they wish to use and encoded IPaddress, of the input interface, in the fragment id ... address as a 16 bit hash of that IPaddress.
