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
Calls superclass method
Resolv::DNS#each_address
# File resolv.rb, line 3134 def each_address(name) name = Resolv::DNS::Name.create(name) return unless name[-1].to_s == 'local' super(name) end
