DNS Name Server Data Storage: Resource Records and Classes (Page 2 of 4) Use of Resource Records and Master Files Each node may have a variable number of records, depending on the node type and what information is being kept for it. The resource records are added, changed or deleted when DNS information changes, by administrators who make modifications to the text master files on the server computer. These files are then read into memory by the DNS server software, parsed (interpreted) and converted into binary form. They are then ready for use in resolving DNS name requests and other queries. This is illustrated in Figure 241. I describe both the binary RR field formats and master file format in the section on DNS messaging and formats.
