NAMErbldns-data - data tool for rbldns
DESCRIPTIONrbldns-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 FORMATip 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, 220.127.116.11/24 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.
