We think you are doing a great job monitoring your systems and/or your networks. We hope that we are not causing any inconvenience.

Modat.io is an Internet search company. We index the Internet at the machine level. Typically, we scan hosts on a daily basis or less.

We publish all of our scanning IP addresses here:

• https://scanner.modat.io/ipv4.txt

Please note that you can block any scans that you do not deem appropriate. We are only scanning. We do not perform any malicious behavior or conduct any actions that can be seen as an intrusion. We uphold the ethics code of scanning and responsible disclosure.

In our HTTP scans, Modat is included in the user agent string. This can help you clearly identify our scans.

Our user agent is: Mozilla/5.0 (compatible; ModatScanner/{__VERSION__}); +https://modat.io/)

You can also identify our scanners through reverse DNS. Our scanners follow this domain pattern:

*.scanner.modat.io

We are part of the worldwide security research community.

Thank you again,
The Modat Team
