Bueno en Debian viene por defecto ya todo listo para ipv6, pero resulta que en mi trabajo pues no tenemos nada que use ipv6 en casa mucho menos, por lo tanto lo \u00fanico que logra la configuraci\u00f3n por defecto de Bind9 es lo siguiente:<\/p>\n

Y si acaso que resuelve m\u00e1s r\u00e1pido opendns que mi dns local… lo cual da al traste con correr un dns de manera local, as\u00ed que me di a la tarea de buscar como hacerlo, en un wiki (wiki.kartbuiding.net<\/a>) halle r\u00e1pidamente la forma de arreglarlo, sin embargo, buscando un poco mas, no encontr\u00e9 de donde salia la opci\u00f3n para hacerlo, en la documentaci\u00f3n lo m\u00e1s que encontr\u00e9 al respecto de la opci\u00f3n -4 fue:<\/p>\n
dual-stack-servers<\/p>\n
    Specifies host names \/ addresses of machines with access to both IPv4 and IPv6 transports. If a hostname is used the server must be able to resolve the name using only the transport it has. If the machine is dual stacked then the dual-stack-servers have no effect unless access to a transport has been disabled on the command line (e.g. named -4).<\/p>\n

Entonces para no tener problemas con el ipv6 es desactivandolo en \/etc\/default\/bind9 (esto en el caso de Debian)<\/p>\n
\r\nvicm3@avalon:~$ more \/etc\/default\/bind9\r\nOPTIONS=\"-4 -u bind\"\r\n#  -4 define only ipv4 queries\r\n<\/pre>\n
Es decir a\u00f1adir -4 en OPTIONS y voila!<\/p>\n","protected":false},"excerpt":{"rendered":"
