The Address Resolution Protocol (ARP) is a fundamental network-layer mechanism for mapping IP addresses to hardware addresses on local networks, and its vulnerability profile reflects the protocol's inherent trust model and minimal authentication mechanisms. Observed disclosures associated with ARP cluster around protocol-design limitations rather than implementation flaws in a specific product, underscoring the structural vulnerability of the protocol itself to spoofing and cache-poisoning attacks that defenders address through network segmentation and monitoring rather than vendor patching. Live severity and exploitation details are shown alongside this summary.
