95.55.237.3 - - [06/Sep/2012:14:38:23 +0400] \"GET / HTTP/1.0\" 200

Answer 1

You could also block specific country

http{
   geoip_country /usr/share/GeoIP/GeoIP.dat;
    map $geoip_country_code $allowed_country {
        default yes;
        FK no;
        FM no;
        EH no;
    }
}

GeoIP.dat can be downloaded from http://dev.maxmind.com/geoip/geoip2/geolite2/ (I am not affiliated with maxmind)
