Blocked by CANTV

Dear friends,

My company has since January 2008 a new ASN and range IP, that RIPE NCC has provided.

The issue is that CANTV that is a service provider of Venezuela have blocked this range ip from the year 2004. I and my providers of transit ip have tried to contact with they but We have not been answered.

Their website show:

" :4: IANA - Reserved (Sep 81) - 1099947465"

* Esta entrada se incluyó en nuestra base de datos el lunes, noviembre 8, 16:57:45 2004 (-0400)

What can I do?

Thank You,

I looked in some looking glass, seems you're OK. I have some routers in venezuela, if you remind me I'll try to trace from there on tuesday.

Re: Blocked by CANTV


Also I tried in some looking glass of America Latina and the result is successful.

I think that the problem is in dns servers of CANTV because I tried doing a traceroute to a domain and failure, but to a IP is sucessful.

Know any telephone or email address?

Re: Blocked by CANTV

Hola Luis,

Gracias por la info, yo hice un tracer inverso a y llego perfectamente.

Al final va a ser problema de las DNS, puedes hacer un dig o un nslookup a y ver si te resuelve.

Si no te resuelve me puedes indicar cual es el telefono de atención al cliente de CANTV. Porque por email no hay forma de que contesten.

Gracias por todo.
