# Public: Determine whether the present device has a connection to
# the Internet. This allows plugin writers which require the outside
# world to have a neat fallback mechanism for offline building.
#
# Example:
# if Internet.connected?
# Typhoeus.get("https://pages.github.com/versions.json")
# else
# Bridgetown.logger.warn "Warning:", "Version check has been disabled."
# Bridgetown.logger.warn "", "Connect to the Internet to enable it."
# nil
# end
#
# Returns true if a DNS call can successfully be made, or false if not.
