Summary
This chapter described the various operations and services provided by the DNS protocol. These operations include queries, recursive and interative (nonrecursive); zone transfers; and dynamic update. I described the process known as reverse mapping, in which a normal query is used to obtain the name of a host given its IP address, and illustrated it with some examples. The chapter concluded with a brief overview of the security implications that necessarily arise from running any DNS service.
Chapter 4 describes a number of name server (DNS) types while recognizing that the majority of name servers are required to provide multiple functions.
