DNS resolution problem

[Marcelo Gondim]

Dear,

I'm having trouble resolving domain name freebsd.org. The portsnap 
server works correctly but the pkg audit -F does not work and can not 
even access the site according to the following tests:

# host ec2-sa-east-1.portsnap.freebsd.org
ec2-sa-east-1.portsnap.freebsd.org has address 177.71.188.240

# host vuxml.freebsd.org
Host vuxml.freebsd.org not found: 3(NXDOMAIN)

# host -a freebsd.org
Trying "freebsd.org"
Trying "freebsd.org.intnet.com.br"
Host freebsd.org not found: 3(NXDOMAIN)
Received 86 bytes from ::1#53 in 0 ms

# host www.freebsd.org
;; connection timed out; no servers could be reached

Only the first address I'm having name resolution 
(ec2-sa-east-1.portsnap.freebsd.org).

My block IP: 186.193.48.0/20

One could check for any restrictions on our IP block?


Thanks and best regards,
Gondim
