rbldns-data(8)                       System Manager's Manual                       rbldns-data(8)



NAME
       rbldns-data - data tool for rbldns


DESCRIPTION
       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 run‐
       ning.  If anything goes wrong with the creation of data.cdb, rbldns-data stops and  leaves
       the old data.cdb in place.


Data format
       ip

       The IP address ip is on the list.

       ip/n

       All  IP  addresses  that share the first n bits of the IP address ip are on the list.  For
       example, 1.2.3.0/24 means all 1.2.3.*  addresses.  n must be at least 8, and all bits past
       the nth in ip must be 0.

       :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 127.0.0.2 and txt is a pointer to a web page about the list.

       If txt ends with $, rbldns(8) replaces the $ with the IP address.

       #comment

       Comment line. The line is ignored.
