  • curprev 15:1515:15, 19 May 2023 2402:3a80:19f5:4a3e::2 talk 24,594 bytes +781 IPv6 uses the Neighbor Discovery Protocol and its extensions such as Secure Neighbor Discovery, rather than ARP. Computers can maintain lists of known addresses, rather than using an active protocol. In this model, each computer maintains a database of the mapping of Layer 3 addresses (e.g., IP addresses) to Layer 2 addresses (e.g., Ethernet MAC addresses). This data is maintained primarily by interpreting ARP packets from the local network link. Thus, it is often called the ARP cache. Since... undo Tags: Reverted Mobile edit Mobile web edit
  • curprev 15:1415:14, 19 May 2023 2402:3a80:19f5:4a3e::2 talk 23,813 bytes +824 Because ARP does not provide methods for authenticating ARP replies on a network, ARP replies can come from systems other than the one with the required Layer 2 address. An ARP proxy is a system that answers the ARP request on behalf of another system for which it will forward traffic, normally as a part of the network's design, such as for a dialup internet service. By contrast, in ARP spoofing the answering system, or spoofer, replies to a request for another system's address with the aim o... undo Tags: Reverted Mobile edit Mobile web edit

  • curprev 15:1415:14, 19 May 2023 2402:3a80:19f5:4a3e::2 talk 28,992 bytes +797 ARP mediation refers to the process of resolving Layer-2 addresses through a virtual private wire service (VPWS) when different resolution protocols are used on the connected circuits, e.g., Ethernet on one end and Frame Relay on the other. In IPv4, each provider edge (PE) device discovers the IP address of the locally attached customer edge (CE) device and distributes that IP address to the corresponding remote PE device. Then each PE device responds to local ARP requests using the IP addres... undo Tags: Reverted Mobile edit Mobile web edit
  • curprev 15:1315:13, 19 May 2023 2402:3a80:19f5:4a3e::2 talk 28,195 bytes +1,030 An ARP probe in IPv4 is an ARP request constructed with the SHA of the probing host, an SPA of all 0s, a THA of all 0s, and a TPA set to the IPv4 address being probed for. If some host on the network regards the IPv4 address (in the TPA) as its own, it will reply to the probe (via the SHA of the probing host) thus informing the probing host of the address conflict. If instead there is no host which regards the IPv4 address as its own, then there will be no reply. When several such probes have... undo Tags: Reverted Mobile edit Mobile web edit

Computer 1 has a packet to send to Computer 2. Through DNS, it determines that Computer 2 has the IP address 192.168.0.55. To send the message, it also requires Computer 2's MAC address. First, Computer 1 uses a cached ARP table to look up 192.168.0.55 for any existing records of Computer 2's MAC address (... undo Tags: Reverted Mobile edit Mobile web edit

RFC 1122 mentions ARP within its link layer section without explicitly placing it within that layer.[4] Some older references place ARP in OSI's data link layer[5] while newer editions associate it with the network layer or introduce an intermediate OSI layer 2.5.[6] undo Tags: Reverted Mobile edit Mobile web edit

Example: Ethernet is 1.[2] Protocol type (PTYPE) This field specifies the internetwork protocol for which the ARP request is intended. For IPv4, this has the value 0x0800.

Its messages are directly encapsulated by a link layer protocol. It is communicated within the boundaries of a single network, never routed across internetworking nodes. undo Tags: Reverted Mobile edit Mobile web edit
