hakrevdns's Introduction

hakrevdns

Small, fast, simple tool for performing reverse DNS lookups en masse.

You feed it IP addresses, it returns hostnames.

This can be a useful way of finding domains and subdomains belonging to a company from their IP addresses.

Installation

go install github.com/hakluke/hakrevdns@latest

Usage

The most basic usage is to simply pipe a list of IP addresses into the tool, for example:

hakluke~$ prips 173.0.84.0/24 | hakrevdns 
173.0.84.110	he.paypal.com.
173.0.84.109	twofasapi.paypal.com.
173.0.84.114	www-carrier.paypal.com.
173.0.84.77	twofasapi.paypal.com.
173.0.84.102	pointofsale.paypal.com.
173.0.84.104	slc-a-origin-pointofsale.paypal.com.
173.0.84.111	smsapi.paypal.com.
173.0.84.203	m.paypal.com.
173.0.84.105	prm.paypal.com.
173.0.84.113	mpltapi.paypal.com.
173.0.84.8	ipnpb.paypal.com.
173.0.84.2	active-www.paypal.com.
173.0.84.4	securepayments.paypal.com.
...

Parameters

hakluke~$ hakrevdns -h
Usage:
  hakrevdns [OPTIONS]

Application Options:
  -t, --threads=           Number of threads (too many may get you banned, too few will be slow)
  -r, --resolver=          IP of the DNS resolver to use for lookups
  -P, --protocol=[tcp|udp] Protocol to use for lookups (default: udp)
  -p, --port=              Port to bother the specified DNS resolver on (default: 53)
  -d, --domain             Output only domains

Help Options:
  -h, --help               Show this help message

If you want to use a resolver not specified by your OS, say: 1.1.1.1, try this:

hakluke~$ echo "173.0.84.110" | hakrevdns -r 1.1.1.1
173.0.84.110    he.paypal.com.

If you wish to obtain only a list of domains without IP addresses, you can use -d:

$ echo "173.0.84.110" | hakrevdns -d

This tool is designed to be easily piped into other tools, for example:

$ echo "173.0.84.110" | hakrevdns -d | httprobe

hakrevdns's Issues

add a option to resolve with a large number of resolvers

-r resolvers.txt

Homebrew formula

Is it possible to create a Homebrew formula to make installation on Mac easier?

features to be added

this tool is amazing BUT it needs two things to be add as flag
1- accept more than one resolver (list of resolvers)
2- accept list of ips to make revers dns for

(feature) custom resolver?

It might be a good idea to include an parameter which would allow users to specify their preferred resolver.

hey,
is there a way that the last "period" when checking can be omitted in the results? currently using sed to remove it.
