This one-day professional level DNS training seminar will show you how to configure the most recent version of BIND for name resolution in a TCP/IP network. You'll learn the history of DNS and BIND from its inception to the present day. Then, you'll learn how to configure a basic DNS installtion including domain name selection, setting up a zone, and setting up the BIND configuration files. You'll see the differences between the different types of name servers including primary masters, secondary masters, caching, and forwarding. We'll show you how to use DNS with mail by setting up MX records. You'll learn how to set up the resolver for host name resolution. We'll explain the key points in adding servers and, as your network grows, adding child domains. We'll explain advanced concepts including zone transfer options, forwarding, the use of ACLs, load distribution, and system tuning. You'll learn the critical tools for managing and troubleshooting BIND DNS including rndc, nslookup, dig, and host. We'll end the day with a look at security options and future considerations with DNS and BIND.
