README

        
## cf-check

Check an Host is Owned by CloudFlare.

## Install

1. Grab from [releases page](https://github.com/dwisiswant0/cf-check/releases), or

2. If you have [Go1.18+](https://go.dev/dl/) compiler installed & configured:

```console

$ go install github.com/dwisiswant0/cf-check@latest

```

## Usage

```console

$ echo "uber.com" | cf-check

34.98.127.226

```

or

```console

$ cf-check -d 

```

### Flags

```console

$ cf-check -h

Usage of cf-check:

  -c int

        Set the concurrency level (default: 20)

  -cf

        Show CloudFlare only

  -d    Print domains instead of IP addresses

```

## Workaround

The goal is that you don't need to do a port scan if it's proven that the IP is owned by Cloudflare.

```console

$ subfinder -silent -d uber.com | filter-resolved | cf-check -d | anew | naabu -silent -verify | httpx -silent

```
