Dear Administrator,<br>
<br>
<pre wrap=""><big>We have some issues regarding some petitions between our DNS:
dns1.terra.es - dns2.terra.es (213.4.132.1 y 213.4.141.1) and the
blackhole.iana.org public DNS.
213.4.132.1 -> blackhole-1.iana.org DNS C 35.11.26.172.in-addr.arpa. Internet PTR ?
213.4.132.1 -> blackhole-1.iana.org DNS C 247.141.22.10.in-addr.arpa. Internet PTR ?
They are sending SSH and telnet petitions to the public DNS, so could
you permit that traffic please.
Thanks in advance
</big></pre>
