# This option should be set to YES to allow the DNS service to
# perform lookups against the locally configured DNS resolver.
# (set to "NO" if no normal ISP is locally available and thus
# requests for normal ".com"/".org"/etc. must be routed via
# the GNUnet VPN (the GNUNET PT daemon then needs to be configured
# to intercept and route DNS queries via mesh).

# Enable GNUnet-wide DNS-EXIT service by setting this value to the IP address (IPv4 or IPv6)
# of a DNS resolver to use. Only works if "PROVIDE_EXIT" is also set to YES. Must absolutely
# NOT be an address of any of GNUnet's virtual tunnel interfaces. Use a well-known
# public DNS resolver or your ISP's resolver from /etc/resolv.conf.
