More Information About S5h.Net Ipv6
Listing on the s5h.net IPv6 blacklist means that you IP has been flagged as a source of sending spam. s5h.net lists IPv6 entries that hit spam traps. This list was created in response to the receipt of increasing volumes of spam originating from IPv6 hosts.
S5h.Net Ipv6 Reports Sources Of Spam
Spam-based Blacklists are those that will list either single IP Addresses or entire ranges that have actually received Spam, i.e. Unsolicited Bulk Email (UBE) in their Spamtraps from an IP-Address. This could be a result of a compromised email account, an Open Relay, or simply sending mass emails / marketing and not following best practices according to the "CAN-SPAM Act of 2003" (ref: https://en.wikipedia.org/wiki/CAN-SPAM_Act_of_2003)
S5h.Net Ipv6 Requires A Manual Delisting Request
This blacklist does support a manual request to remove or delist your IP Address from their database. Please note that removal requests that are submitted without addressing the core problem will likely result in your IP Address or Domain being relisted in that database, which can cause subsequent problems and extended listing periods without release.
