rbldns-data - blacklist generation for rbldns


		 rbldns-data reads an IP address list from a file named data in the
		 current directory.  It creates data.cdb in a binary format designed for
		 fast access by rbldns.

		 rbldns-data updates data.cdb atomically, so you can use it safely while
		 rbldns is running.  If anything goes wrong with the creation of
		 data.cdb, rbldns-data stops and leaves the old data.cdb in place.


		 ip4 : The IPv4 address ip4 given in dotted decimal format is on the

		 ip4/n : All IPv4 addresses that share the first n bits of the IP
		 address ip4 are on the list.  For example, 1.2.3./24 means all 1.2.3.*

		 ip6 : The IPv6 address ip6 provided in compactified format is on the

		 ip6/n : All IPv6 addresses sharing the first n bits of ip6 are
		 considered.  A rule 2002:/16 would block all 6to4 addresses.  For
		 practical reasons, n needs to smaller/equal than 64, since the lower
		 bits of an IPv6 address denominates the link token and is not relevant
		 for routing.

		 =a:txt : DNS queries for addresses on the list will receive an A record
		 of a and a TXT record of txt.  Typically a is and txt is a
		 pointer to a web page about the list.

		 If txt ends with $, rbldns replaces the $ with the IP address.

		 #comment : Comment line. The line is ignored.

		 Note: The generated data.cdb is not binary compatible with older
		 versions of rbldns.  In addition, IP addresses are evaluated at bit
		 level to comply with the CIDR requirements.
