The Serial field from the Start Of Authority (SOA) resource record is a good example of a zone's version, and the only one defined by this specification. Additional version types may be defined by future specifications. Including zone version data in a response simplifies and improves the quality of debugging and and diagnostics since the version and the data are provided atomically. This can be especially useful for zones and DNS providers that leverage IP anycast or multiple backend systems. It functions similarly to the NSID option.}, }
