A command-line utility for performing reverse DNS lookups
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" | revitcat 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.
