After the client obtains an IP address, it should probe the newly received address: sec. 2.2 (e.g. with ARP Address Resolution Protocol) to prevent address conflicts caused by overlapping address pools of DHCP servers. If this probe finds another computer using that address, the computer should send DHCPDECLINE, broadcast, to the server.
In computer networking, a routing table, or routing information base ( RIB ), is a data table stored in a router or a network host that lists the routes to particular network destinations, and in some cases, metrics (distances) associated with those routes. The routing table contains information about the topology of the network immediately ...
A VIP address can be used to provide nearly unlimited mobility. For example, if an application has an IP address on a physical subnet, that application can be moved only to a host on that same subnet. VIP addresses can be advertised on their own subnet, so its application can be moved anywhere on the reachable network without changing addresses.
Locator/ID Separation Protocol (LISP) (RFC 6830) is a "map-and-encapsulate" protocol which is developed by the Internet Engineering Task Force LISP Working Group. The basic idea behind the separation is that the Internet architecture combines two functions, routing locators (where a client is attached to the network) and identifiers (who the ...
In computing, a stateful firewall is a network-based firewall that individually tracks sessions of network connections traversing it. Stateful packet inspection, also referred to as dynamic packet filtering, [1] is a security feature often used in non-commercial and business networks.
The network host IP interface binds the gateway address to the MAC address of the physical gateway by broadcasting IP datagrams and caching the MAC address of the reply from the gateway in an ARP table stored on the host. The gateway address may be added manually. On Windows computers, the gateway address is configured using the TCP/IP ...
Virtual Private LAN Service (VPLS) is a way to provide Ethernet-based multipoint to multipoint communication over IP or MPLS networks. It allows geographically dispersed sites to share an Ethernet broadcast domain by connecting sites through pseudowires. The term sites includes multiplicities of both
IP packets originating from or addressed to a private IP address cannot be routed through the public Internet. Private addresses are often seen as enhancing network security for the internal network, since use of private addresses internally makes it difficult for an external host to initiate a connection to an internal system.
