    Happy Eyeballs (also called Fast Fallback) is an algorithm published by the IETF that makes dual-stack applications (those that understand both IPv4 and IPv6) more responsive to users by attempting to connect using both IPv4 and IPv6 at the same time (preferring IPv6), thus minimizing IPv6 brokenness and DNS whitelisting experienced by users that have imperfect IPv6 connections or setups.

  8. IPv6 - Wikipedia

    en.wikipedia.org/wiki/IPv6

    IPv6 implements the Neighbor Discovery Protocol (NDP, ND) in the link layer, which relies on ICMPv6 and multicast transmission. [5]: 210 IPv6 hosts verify the uniqueness of their IPv6 addresses in a local area network (LAN) by sending a neighbor solicitation message asking for the link-layer address of the IP address. If any other host in the ...

  9. Provider-independent address space - Wikipedia

    en.wikipedia.org/wiki/Provider-independent...

    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.
