[edit] Zones

One can track the bogon allocations through DNS. This is accomplished by launching a query in the bogons.cymru.com zone

The query style is in-addr.arpa format, e.g. the IP address is reversed in and prepended to the .bogons.cymru.com domain. If the A RR is 127.0.0.2, then the IP address in the query above is part of a bogon prefix. All of the IPs within a bogon prefix are covered by the zone file, which uses wildcard matches to properly respond to queries within a bogon prefix. The DNS bogon checking can be used for RBL-style filtering.

Zone transfers of the entire bogons.cymru.com zone are permitted from noquar.as23028.net and drider.as23028.net.
