自定义fall-back组代码

# If IP addresses resolved with servers in `nameservers` are in the specified
# subnets below, they are considered invalid and results from `fallback`
# servers are used instead.
#
# IP address resolved with servers in `nameserver` is used when
# `fallback-filter.geoip` is true and when GEOIP of the IP address is `CN`.
#
# If `fallback-filter.geoip` is false, results from `nameserver` nameservers
# are always used if not match `fallback-filter.ipcidr`.
#
# This is a countermeasure against DNS pollution attacks.
