Overview

DNS Change

Represents a request containing additions or deletions or records. Additions and deletions can be done in bulk, in a single atomic transaction, and take effect at the same time in each authoritative DNS server.

Examples:

require "google/cloud/dns"

dns = Google::Cloud::Dns.new
zone = dns.zone "example-com"
zone.changes.each do |change|
  puts "Change includes #{change.additions.count} additions " \
       "and #{change.additions.count} deletions."
end
