BIND and Geo IP

BIND added GeoIP support in Version 9.10; it involves defining separate BIND views based on each geographical area.Take a look at this code block:

options {
        geoip-directory "/path/to/geoip/database";
};

acl "redwoodcity" { 
        geoip country US;
        geoip region CA;
        geoip city "Redwood City"; 
        /* names, etc., must be quoted if they contain spaces */
};

view "redwoodcity" {

        match-clients { redwoodcity; }; zone "isc.org" {
                file "locals/db.isc.org"; type master;
        };

};

view "default" { zone "isc.org" {
        file "nonlocals/db.isc.org"; type master;
};

On its own, you might find it unwieldy to try to implement a public-facing GeoDNS implementation using BIND views—it would necessitate creating ACLs for each geographical region. Enter http://phix.me/geodns/ ...
