Best Current Practice [Page 1] RFC 2929 DNS IANA Considerations September 2000 1. Introduction The Domain Name System (DNS) provides replicated distributed secure hierarchical databases which hierarchically store "resource records" (RRs) under domain names. This data is structured into CLASSes and zones which can be independently maintained. See [RFC 1034, 1035, 2136, 2181, 2535] familiarity with which is assumed. This document covers, either directly or by reference, general IANA parameter assignment considerations applying across DNS query and response headers and all RRs.

This category contains only one function: dns.lookup(). Developers looking to perform name resolution in the same way that other applications on the same operating system behave should use dns.lookup(). For example, looking up nodejs.org. const dns = require('dns'); dns.lookup('nodejs.org', (err, addresses, family) => { console.log('addresses:', addresses); }); 2) Functions that connect to an actual DNS server to perform name resolution, and that always use the network to perform DNS queries. This category contains all functions in the dns module except dns.lookup(). These functions do not use the same set of configuration files used by dns.lookup() (e.g. /etc/hosts). These functions should be used by developers who do not want to use the underlying operating system's facilities for name resolution, and instead want to always perform DNS queries. Below is an example that resolves 'nodejs.org' then reverse resolves the IP addresses that are returned. const dns = require('dns'); dns.resolve4('nodejs.org', (err, addresses) => { if (err) th
