The group of redundancy allocates itself an IP address which is shared or divided among the members of the group. Within this group, a host is designated as "active/primary". The other members are "standby". The main host is that which "takes" the IP address. It answers any traffic or ARP request brought to the attention of this address. Each ...
The Address Resolution Protocol (ARP) is a communication protocol used for discovering the link layer address, such as a MAC address, associated with a given internet layer address, typically an IPv4 address. This mapping is a critical function in the Internet protocol suite. ARP was defined in 1982 by RFC 826, which is Internet Standard STD 37.
The arptables computer software utility is a network administrator's tool for maintaining the Address Resolution Protocol (ARP) packet filter rules in the Linux kernel firewall modules. The tools may be used to create, update, and view the tables that contain the filtering rules, similarly to the iptables program from which it was developed.
iproute2 utilities communicate with the Linux kernel using the netlink protocol. Some of the iproute2 utilities are often recommended over now-obsolete net-tools utilities that provide the same functionality. [4] [5] Below is a table of obsolete utilities and their iproute2 replacements.
arping is a computer software tool for discovering and probing hosts on a computer network.Arping probes hosts on the examined network link by sending link layer frames using the Address Resolution Protocol (ARP) request method addressed to a host identified by its MAC address of the network interface.

Proxy ARP is a technique by which a proxy server on a given network answers the Address Resolution Protocol (ARP) queries for an IP address that is not on that network. The proxy is aware of the location of the traffic's destination and offers its own MAC address as the (ostensibly final) destination. [ 1 ]
Network access control is a computer networking solution that uses a set of protocols to define and implement a policy that describes how to secure access to network nodes by devices when they initially attempt to access the network. [3]
arpwatch is a computer software tool for monitoring Address Resolution Protocol traffic on a computer network. [1] It generates a log of observed pairing of IP addresses with MAC addresses along with a timestamp when the pairing appeared on the network.
