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 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.

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 n th 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.
