Block DNS reverse-mapping queries to the AS112 servers from leaving the site using firewalls between the site and the Internet. Manderson, "Nameservers for IPv4 and IPv6 Reverse Zones", BCP 155, RFC 5855, May 2010. [RFC6303] Andrews, M., "Locally Served DNS Zones", BCP 163, RFC 6303, July 2011. [RFC6304] Abley, J. It works with the Regional Internet Registries (RIRs) to distribute the large blocks of IP addresses among the RIRs. All of the addresses within the loopback address are treated with the same levels of restriction in Internet routing, so it is difficult to use any other addresses within this block

The network address is rearranged in order to construct a name that can be looked up in the DNS. These queries are ambiguous by their nature, and can not be answered correctly. It is just odd I should be getting these type of requests - I went ahead and bocked the range of - 255.As for the DHCP assigning an IP..

Because of the caching noted above, this is far better than simply not responding at all, so the blackhole servers are provided as a public service. While inverse queries are rare from a human perspective, some network services automatically do an inverse lookup whenever they process a request from a particular IP address, and consequently they form

Moreover, even if such a person is found, they may well be halfway around the world, and not share your language or your legal system.

In a bad mood?

The IANA blackhole servers respond to these inverse queries, and always return an answer that says, authoritatively, that "this address does not exist". Why does one have to check if axioms are true? Hence the many instances of this address in the DNS logs / Event Viewer.

not to mention that all of my on line accounts have been hacked and well as my systems. pop over to these guys Hints for finding the person responsible for an IPv4 address If you encounter an IPv4 address that does not fit any of the above categories, researching the various information sources to This document provides background information and technical advice to those firewall operators. Providing negative answers reduces the load on the public DNS infrastructure.

If it doesn't respond for the zone, the authoritative will be contacted. Later the group of volunteers has grown to include many other organizations. Edit It looks like you have a PTR (reverse) zone for the subnet specified on your DNS. But you should make every effort to fix the problem from your end, because episodes of overload to the blackhole servers are becoming more common, and that can have more serious

A4: While rates vary, the blackhole servers generally answer thousands of queries per second. I run Norton firewall on both computers. If you see an apparent attack, or spam, coming from one of these address ranges, then either it is coming from your local environment, your ISP, or the address has been

Nonetheless, you must decide if it is worth the effort to try.

(Please note that the blackhole servers used to be located at isi.edu). Hence, an inverse lookup on one of these addresses should never work. Our core function is as a Regional Internet Registry.

Maton, "AS112 Nameserver Operations", RFC 6304, July 2011. The IANA is preparing a FAQ on this topic -- one of these days it should be posted on the IANA web site.

Because of the caching noted above, this is far better than simply not responding at all, so the IANA provides the blackhole servers as a public service.

IANA was the name of the organization that was responsible for handing out IP address blocks back in the day. Hence, an inverse lookup on one of these addresses should never work. In the past couple of years the number of queries to the blackhole servers has increased dramatically. In some cases, servers can be configured not to perform DNS reverse-mapping lookups, for example.

Remove the zone and it will go to the root. In virtually all such cases, the association of the IANA name with a particular address is not actually useful in dealing with the abuse incident. A trojan?Recently,I'd been getting a request from to access my network. A5: No system is totally safe from hackers, and the blackhole servers are no exception.

Mailing list for AS112 operators. This can happen if the private intranet is internally using services that automatically do reverse queries, and the local DNS resolver needs to go outside the intranet to resolve these names. Could it be that a hacker has taken over the servers, and is attacking other systems? Since queries sent to AS112 servers are usually not intentional, the replies received back from those servers are typically unexpected.
