Resolv::MDNS
class Resolv::MDNS
Resolv::MDNS is a one-shot Multicast DNS (mDNS) resolver. It blindly makes queries to the mDNS addresses without understanding anything about multicast ports.
Information taken form the following places:
-
RFC 6762
Constants
Public Class Methods
Creates a new one-shot Multicast DNS (mDNS) resolver.
config_info
can be:
- nil
-
Uses the default mDNS addresses
- Hash
-
Must contain :nameserver or :nameserver_port like Resolv::DNS#initialize.
# File lib/resolv.rb, line 2581 def initialize(config_info=nil) if config_info then super({ nameserver_port: Addresses }.merge(config_info)) else super(nameserver_port: Addresses) end end
Public Instance Methods
Iterates over all IP addresses for name
retrieved from the mDNS resolver, provided name ends with “local”. If the name does not end in “local” no records will be returned.
name
can be a Resolv::DNS::Name or a String. Retrieved addresses will be a Resolv::IPv4 or Resolv::IPv6
# File lib/resolv.rb, line 2597 def each_address(name) name = Resolv::DNS::Name.create(name) return unless name.to_a.last == 'local' super(name) end
