Hi,
We, have recently acquired the /24 subnet of IP address (216.170.117.0 - 216.170.117.255). It appeared that all of IP addresses from this range were blacklisted because of: "The host has been observed sending spam in a format that is similar to snow shoe spamming techniques."
How can I clean up the reputation of this subnet of IPs?
Thank you,
Mykola Denysiuk,
