IP-based Rule

There are 3 IP-based rule types. A IP-based rule will trigger a DNS lookup if the hostname of the request is a domain. If the DNS lookup fails, Surge will abort the rule testing and report an error.

IP-CIDR

IP-CIDR,192.168.0.0/16,DIRECT
IP-CIDR,10.0.0.0/8,DIRECT
IP-CIDR,172.16.0.0/12,DIRECT
IP-CIDR,127.0.0.1/8,DIRECT

Rule matches if the IP address of the request matches a specified range.

IP-CIDR6

IP-CIDR6,2001:db8:abcd:8000::/50,DIRECT

Rule matches if the IPv6 address of the request matches a specified range.

GEOIP

GEOIP,US,DIRECT

Rule matches if the GeoIP test result matches a specified country code.

IP-ASN

IP-ASN,1234,DIRECT

Rule matches if the autonomous system number of the remote IP address matches.

IP-based Rule Parameters

no-resolve

GEOIP,US,DIRECT,no-resolve
IP-CIDR,172.16.0.0/12,DIRECT,no-resolve

When a GEOIP or IP-CIDR rule is encountered, Surge will send a DNS query to check if the hostname of request is a domain. You can select 'no-resolve' option to skip this rule for a request with domain.

Notice: If some domains can't be resolved by local DNS server, please make sure there is no IP-based rule in front of the rule which matches that domain. Otherwise the rule testing will fail due to a DNS error. You can use 'no-resolve' to solve the issue too.
