Requirements for a Protocol to Replace
the AppleTalk Name Binding Protocol (NBP)
Abstract
One of the goals of the authors of Multicast DNS (mDNS) and DNS-Based
Service Discovery (DNS-SD) was to retire AppleTalk and the AppleTalk
Name Binding Protocol (NBP) and to replace them with an IP-based
solution. This document presents a brief overview of the
capabilities of AppleTalk NBP and outlines the properties required of
an IP-based replacement.

RFC 6760 Replacement of AppleTalk NBP February 2013
1. Introduction
An important goal of the participants working on Zeroconf, Multicast
DNS, and DNS-Based Service Discovery was to provide a viable IP-based
replacement for AppleTalk and the AppleTalk Name Binding Protocol
(NBP).
There are many who are experts in the Domain Name System (DNS) who
know nothing about the AppleTalk Name Binding Protocol (NBP).
Without some background on how AppleTalk and NBP worked, it may be
difficult to understand the reasoning and motivations that led to the
design decisions in Multicast DNS and DNS-Based Service Discovery.
This document seeks to remedy this problem by clearly stating the
