[6] RFC 3755 designates DNSKEY as the replacement within DNSSEC. [7] RFC 4025 designates IPSECKEY as the replacement for use with IPsec. [8]
However, in practice, the root nameserver infrastructure is highly resilient and distributed, using both the inherent features of DNS (result caching, retries, and multiple servers for the same zone with fallback if one or more fail), and, in recent years, a combination of anycast and load balancer techniques used to implement most of the ...
