Overview

Name

Net::DNS::RR::A DNS A resource record

Synopsis

require “net/dns/rr”

Description

Net::DNS::RR::A is the class to handle resource records of type A, the most common in a DNS query. Its resource data is an IPv4 (i.e. 32 bit long) address, hold in the instance variable address.

a = Net::DNS::RR::A.new("localhost.movie.edu. 360 IN A 127.0.0.1")

a = Net::DNS::RR::A.new(:name    => "localhost.movie.edu.",
                        :ttl     => 360,
                        :cls     => Net::DNS::IN,
                        :type    => Net::DNS::A,
                        :address => "127.0.0.1")

When computing binary data to trasmit the RR, the RDATA section is an Internet address expressed as four decimal numbers separated by dots without any imbedded spaces (e.g.,“10.2.0.52” or “192.0.5.6”).
