Naming, Numbering and Addressing robertshaw.info references to telecommunications and Internet naming, numbering and addressing issues. ![]() Toward Lowering the Load on DNS Root NameserversToward Lowering the Load on DNS Root Nameservers (PDF) by Duane Wessels of The Measurement Factory and CAIDA, suggests that over 95% of the roughly 100 million daily queries to each root server are invalid and unnecessary queries. 1:16:18 PM![]() Distributing the K-Root Service by Anycast RoutingRIPE NCC operates the K-root server (k.root-servers.net). They have recently published a draft on Distributing the K-Root Service by Anycast Routing of 193.0.14.129. The application of anycasting to providing DNS services was explored in a number of Internet drafts which eventually became the informational RFC 3258: Distributing Authoritative Name Servers via Shared Unicast Addresses. RFC 3258 describes how authoritative name servers with the same IP address could be replicated at different locations. The route to these servers would be advertised for each location and the routing protocols would direct traffic to the topologically nearest server. See my earlier note on this topic. 11:57:01 AM![]()
