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 Reverse Address Resolution Protocol (RARP) is an obsolete computer communication protocol used by a client computer to request its Internet Protocol address from a computer network, when all it has available is its link layer or hardware address, such as a MAC address. [1]
This is a list of the IP protocol numbers found in the field Protocol of the IPv4 header and the Next Header field of the IPv6 header.It is an identifier for the encapsulated protocol and determines the layout of the data that immediately follows the header.
The program is allowed to edit the packet data and, after the eBPF program returns, an action code determines what to do with the packet: XDP_PASS: let the packet continue through the network stack; XDP_DROP: silently drop the packet; XDP_ABORTED: drop the packet with trace point exception; XDP_TX: bounce the packet back to the same NIC it ...
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.
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.

Communications protocols use various conventions for distinguishing the elements of a packet and for formatting the user data. For example, in Point-to-Point Protocol, the packet is formatted in 8-bit bytes, and special characters are used to delimit elements. Other protocols, like Ethernet, establish the start of the header and data elements ...
