revit

A command-line utility for performing reverse DNS lookups

🏗️ Install ⛏️ Usage

Install

To install revit, run the following command:

go install github.com/devanshbatham/revit/cmd/revit@v0.0.1

Usage

This utility allows you to perform reverse DNS lookups on IP addresses. Here are some examples of how to use the tool:

• Look up a single IP address:

revit -i "8.8.8.8"

• Look up a list of IP addresses from a file:

revit -l ip_list.txt

• Pipe input from another command:

echo "8.8.8.8" | revit

cat ip_list.txt | revit

Here are the available command-line flags:

Flag	Description	Example
-i	Specify a single target IP address for reverse DNS lookup.	revit -i 8.8.8.8
-l	Provide the path to a file containing a list of IP addresses.	revit -l ip_list.txt
-c	Set the level of concurrency for concurrent DNS lookups (default: 10).	revit -c 20
-r	Specify resolvers for reverse DNS lookup.	revit -r 8.8.8.8
	You can provide a single IP address or a path to a file.	revit -r resolvers.txt

Inspiration

revit was born out of curiosity and a desire to explore Golang. While there are existing tools like hakrevdns that perform similar tasks (and I have immense respect for them), I decided to create this utility as a personal project to further my understanding of Go and enhance my programming skills.

The development of revit started as an exploration into concurrent programming and networking in Go. As I tinkered with the language's features and learned more about its capabilities, the utility began to take shape.
