Creating a server

  port: 8053,
  authority: ["ns.ractordns.local", 300, RRs::IN::A.new("1.1.1.1")], 
  cpu_count: 12,
  zones: {
    "google.com" => [
      {
        name: "google.com",
        ttl: 300,
        rr: RRs::IN::A.new("8.8.8.8")
      },
      {
        name: "test.google.com",
        ttl: 300,
        rr: RRs::IN::A.new("1.1.1.1")
      }
    ]
  }

Updating zones

transaction = RactorDNS::Transaction.new do |zones|
  zones["google.com"][0][:rr] = RRs::IN::A.new("2.2.2.2")
end

server.zones.transact transaction
