Re: Spamhaus flags any IP announced by our ASN as a criminal network

afaik, spamhaus starts to mark a whole AS as criminal, if there is to much abuse. It seems you've reached the point that they ignore specific prefixes and set every prefix you are advertising as criminal.

We even haven't started to use, we just announced that... They marked it's a criminal network

    Given the list of things on these two prefixes alone, I would
    venture to guess it's not a misjudgement.

        Hello guy,

        We recently discovered that any IP address announced by our
        ASN is blacklisted by Spamhaus, even if we only announced it
        but not use it.

        I would like to ask if this is manually set by Spamhaus or is
        the system misjudgment? Has anyone encountered the same
        situation as us?


        Best,
