       rbldns-data - data tool 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(8).   It  may  also
       create some other files with names beginning with data.

       rbldns-data  updates  data.cdb  atomically,  so  you  can use it safely while rbldns(8) is
       running.  If anything goes wrong with the creation  of  data.cdb,  rbldns-data  stops  and
       leaves the old data.cdb in place.

Data format


       The IP address ip is on the list.


       All  IP  addresses  that share the first n bits of the IP address ip are on the list.  For
       example, means all 1.2.3.*  addresses.  n must be at least 8, and all bits past
       the nth in ip must be 0.


       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(8) replaces the $ with the IP address.
