[dns-esp] WARNING: recursion requested but not available

[Ricardo Barquero Carranza]

Saludos,

Tengo una duda en cuanto a una recursión. Tengo una ip reversa funcionando correctamente en mi DNS

dig -x 190.241.253.252 @196.40.15.200

; <<>> DiG 9.7.0-P1 <<>> -x 190.241.253.252 @196.40.15.200

Sin embargo cuando pregunto a un server externo me indica dominio inexistente

dig -x 190.241.253.252 @4.2.2.2

Observo que responde como autoridad a NS.LACNIC.NET. Al preguntarle directamente a ese DNS me indica un error de recursión.

dig -x 190.241.253.252 @NS.LACNIC.NET

El tema que no entiendo es pq no permite la recursión:  WARNING: recursion requested but not available
