The Neighbor Discovery Protocol (NDP), or simply Neighbor Discovery (ND), is a protocol of the Internet protocol suite used with Internet Protocol Version 6 (IPv6). [1]: §1 It operates at the internet layer of the Internet model, [2] and is responsible for gathering various information required for network communication, including the configuration of local connections and the domain name ...
In computing, netsh, or network shell, is a command-line utility included in Microsoft's Windows NT line of operating systems beginning with Windows 2000. [1] It allows local or remote configuration of network devices such as the interface .
A provider-independent address space (PI) is a block of IP addresses assigned by a regional Internet registry (RIR) directly to an end-user organization. [1] The user must contract [ 2 ] with a local Internet registry (LIR) through an Internet service provider to obtain routing of the address block within the Internet .
Used for link-local addresses [5] between two hosts on a single link when no IP address is otherwise specified, such as would have normally been retrieved from a DHCP server 172.16.0.0/12 172.16.0.0–172.31.255.255
When IPv6 hosts configure their network interface controllers, they multicast router solicitation (RS) requests onto the network to discover available routers. Radvd answers requests with router advertisement (RA) messages. In addition, radvd periodically multicasts RA packets to the attached link to update network hosts.
The Internet Engineering Task Force (IETF) has reserved the IPv4 address block 169.254.0.0 / 16 (169.254.0.0 – 169.254.255.255) for link-local addressing. [1] The entire range may be used for this purpose, except for the first 256 and last 256 addresses (169.254.0.0 / 24 and 169.254.255.0 / 24), which are reserved for future use and must not be selected by a host using this dynamic ...
[1] [2] NDPMon observes the local network for anomalies in the function of nodes using Neighbor Discovery Protocol (NDP) messages, especially during the Stateless Address Autoconfiguration. [3] When an NDP message is flagged, it notifies the administrator by writing to the syslog or by sending an email report.
A solicited-node multicast address is an IPv6 multicast address used by the Neighbor Discovery Protocol to determine the link layer address associated with a given IPv6 address, which is also used to check if an address is already being used by the local-link or not, through a process called DAD (Duplicate Address Detection). The solicited-node ...
