jdresolve resolves IP addresses to hostnames. Any file format is
|
|
supported, including those where the line does not begin with the IP
|
|
address. One of the strongest features of the program is the support
|
|
for recursion, which can drastically reduce the number of unresolved
|
|
hosts by faking a hostname based on the network that the IP belongs
|
|
to. DNS queries are sent in parallel, which means that you can
|
|
decrease run time by increasing the number of simultaneous sockets
|
|
used (given a fast enough machine and available bandwidth). By using
|
|
the database support, performance can be increased even further, by
|
|
using cached data from previous runs.
|
|
|
|
Included is a tiny shell script called rhost to interface with
|
|
jdresolve when resolving a single IP address. Think of it as a smart
|
|
replacement for the 'host' utility that comes with bind-utils.
