From RFC1034 section 4.1, it seems that the way used for improving the redundancy and resilience of DNS system is to increase DNS servers.
It might be better to start from RFC2182 "Selection and Operation of Secondary DNS Servers", a mere 17 years old rather than 27 (and a lot more detailed) although it still predates widespread use of anycast in the DNS context. Nothing has officially superceded RFC2182 and it remains a Best Common Practice document (BCP0016). -- Chris Thompson University of Cambridge Information Services, Email: c...@uis.cam.ac.uk Roger Needham Building, 7 JJ Thomson Avenue, Phone: +44 1223 334715 Cambridge CB3 0RB, United Kingdom. _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
