RFC 8109 Rounds Off DNS Specification
All texts explaining how the DNS works contain a sentence like "... then the resolver sends the query to a root name server ...". But how does the resolver know these servers and what happens if their addresses have changed? The process to solve this problem is called "priming". Until recently it had not been described in an official document and, moreover, it underwent minor changes in the course of the years, also due to the introduction of IPv6. This documentation gap is now closed by the RFC 8109 "Initializing a DENS Resolver with Priming Queries", a "Best Current Practice" document of the IETF, which was compiled by Peter Koch of DENIC in cooperation with two staff members of ICANN.
