Malicious Use of AS1221

As with any large network, there is potential for abuse by hackers or spammers. However, Telstra, like many major ISPs, has policies and measures in place to combat such activities. According to data from CleanTalk, it is possible for networks, including AS1221, to occasionally be exploited for malicious intent. CleanTalk provides a blacklist that can include IP addresses associated with spam or hacking activities, which may involve entities within AS1221. Nonetheless, this does not necessarily reflect widespread misuse of Telstra's services but rather isolated incidents that can occur within any large network.

For security reasons and maintaining the integrity of this response, specific details about the misuse or blacklisting status from external sources like CleanTalk are not provided here.
