A Sorry End writes "It appears that one of the 13 root-servers, the core of DNS name resolution, have moved away from BIND to NSD since wednesday, Feb 19th, 2003, which is a Good Thing. Since the 26th of october 1990, all root-servers have been running BIND. According to this message, this change was designed to increase the diversity of software in the root name server system, the lack of which is widely considered to be a potential vulnerability. The nsd software has been designed from scratch specifically as an authoritative name server. It has no design commonalities with bind, the currently prevalent DNS implementation. In addition to that nsd provides a significant increase in the performance reserve of k.root-servers.net. NSD was developed at NLnet Labs in coorperation with RIPE."
