Important Note: 1c04:0:21:: is a private IP address, and is only used in internal network environments. Any abusive activity you see coming from an internal IP is either coming from within your network itself, or is the result of an error or misconfiguration.

With this in mind, we present the reports on this page for entertainment and testing purposes only. If you mistakenly blacklist an internal IP, you will not have a good day!
