Production DNS infrastructure
To handle all requests from production network and external queries the name servers and resolvers have been separated. - A single master name server updates 4 slaves with AXFR transactions. - All slaves have been configured to serve requests for about 1200 public domains. - 2 views have been created for internal and external DNS clients. - 4 resolvers are placed behind 2 vips to optimize load sharing and provide high availability. - All systems are Debian servers with BIND.
