What is the RFC number for Neighbor Discovery Protocol (NDP)?

Explanation:
NDP is defined for IPv6 and runs over ICMPv6 to handle neighbor discovery, address resolution, duplicate address detection, and router discovery. The document that originally defined this protocol is RFC 2461. Although RFC 4861 later updates and supersedes it, 2461 is the classic reference for NDP. The other numbers correspond to different IPv6 topics: 2460 is the IPv6 base specification, 2462 relates to host configuration, and 2463 covers ICMPv6-related topics. So the correct RFC number for Neighbor Discovery Protocol is 2461.
