Funkce GeoIP


Na všechny servery byla přidána možnost snadné lokace návštěvníků odkud přicházejí. Na základě proměnných tak lze v PHP snadno určit kontinent a stát každé návštěvy stránek.

_SERVER["GEOIP_ADDR"]
  • například: 192.121.113.222
_SERVER["GEOIP_CONTINENT_CODE"]
  • například: EU
_SERVER["GEOIP_COUNTRY_CODE"]
  • například: CZ
_SERVER["GEOIP_COUNTRY_NAME"]
  • například: Czech Republic

Proměnné jsou k dispozici v PHP jako superglobální, tedy ve všech skriptech a funkcích.

Funkce GeoIP umožňuje podrobnější určení místa návštěvníka stránek, ale vzhledem k malé přesnosti, která nedosahuje v ČR ani 75% jsme ji neimplementovali. Databáze IP adres je každý měsíc automaticky aktualizována.

Blokování přístupu pomocí funkce GeoIP 

Pomocí funkce GeoIP je možné blokovat přístup k webovým stránkám z určité země. Často se můžete setkat s mnoha přístupy z Ruska nebo Číny pro které webovou prezentaci nevytváříte a roboti z těchto zemí často na Vašich stránkách zanechávají mnoho příspěvků v komentářích nebo diskuzích. Zablokování se provádí pomocí souboru .htaccess do kterého vložíte na začátek tento kód:

GeoIPEnable On
# Zde umístěte země které si přejete blokovat (Čína a Rusko)    
SetEnvIf GEOIP_COUNTRY_CODE CN DenyCountry
SetEnvIf GEOIP_COUNTRY_CODE RU DenyCountry  
  
Allow from all
Deny from env=DenyCountry 

 

Každá země má pak svůj unikátní kód, pokud si tedy přejete zablokovat přístup z jiné země, je nutné upravit/přidat pravidlo s kódem dané země.
