rufoqe · #1 (**permalink**) 27/12/2010, 16:15

Hola a todos, mi duda es esta
¿existe alguna manera de prohibir ver o entrar a usuarios de cierto continente o de cierto pais? algo asi como un baneo por area o pais, digamos un ejemplo, quisiera que mi blog no sea visible para los habitantes de china, existe alguna manera??? no se si modificandole algo desde el panel de administracion o baneando determinado codigo de region, expliquenme como le hago, por favor, aprovecho para desearles una feliz navidad y un prospero año nuevo 2011!!!

Hola:

Creo que es muy difícil saber la ubicación de todos los usuarios con exactitud, pero hay una librería llamada iptocountry que según la ip (que se puede saber por ejemplo con php), determina el país de procedencia... luego será cuestión, por ejemplo de redireccionar.

Saludos

Con los de todo un continente va a ser un poco dificil, ahora que si es un pais, podés usar esta herramienta
http://www.find-ip-address.org/ip-country/

y colocar en tu htaccess la lista de ip's a bloquear, con eto bloquearias el acceso a tu web desde Afganistán...

Es posible tener una aproximación de la ubicación, tal como menciona Caricatos. Puedes usar tanto la geolocalización HTML5 o usar bases de datos de IPs; la primera es mucho más confiable, pero requiere que el usuario autorice compartir su ubicación, la segunda depende de que tan actualizada está la base de datos, por le regular solo es precisa a nivel de país.

Pregunto?

La metamorfosis de Caricatos a JavierB? está relacionada con la actualización de la base de datos u obedece a cuestiones más esotéricas?

Lo que comenta emprear es una posible solución.
En un blog que tengo en un hosting con Apache de servidor web, recibía multitud de ataques desde China, tantos que decidí matar las moscas a cañonazos y denegué el acceso a todas las IPs de china:

ver: Bloquear Accesos por País a servidor web Apache.

Consulté las IPs v4 de China en http://www.countryipblocks.net/count...elect-formats/
Como dejé el fichero .htaccess

Código Apache:

Ahora los ataques han bajado un 90% y el 10% restante suelen proceder de Argentina, España, Brasil, Turquía y Rusia sobre todo.
