If you’re using security technologies like a Next-Gen Firewall, Intrusion Prevention System (IPS), Intrusion Detection System (IDS), or a Web Application Firewall (WAF), they may flag Catcher's traffic as suspicious and block it. We recommend allowlisting our IP ranges to avoid these problems.
This article provides the full list of IP ranges you’ll need to configure in your security tools to avoid false positives or blocked traffic during scans.
95.211.123.176/28

FAQ
Where should I add these ranges?
You should add these ranges to the appropriate IPS, IDP etc. you have enabled.
If your applications are hosted by a 3rd party, please inform them that you will run scans from these ranges, to avoid your 3rd party blocking our IPs.
What about my firewall?
If you use a perimeter firewall, please don't add our ranges to it as that would show results which aren't accessible through the internet normally.
