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
```
