# 1 = Enable fallback DNS servers, overrides /etc/resolv.conf in case of DNS failure
# Recommended:
#
# - curl built with options '--enable-dnsshuffle' & '--enable-ares'
#     - if you work only on IPv4 environments, it is strongly recommended to build curl with '--disable-ipv6'
#       as fallback name resolution attempts may fail otherwise
