Blocklists for MikroTik RouterOS

Address list per script

Fetch the list and import it into an address list called blocklist:

/tool fetch url="https://www.team-cymru.org/Services/Bogons/fullbogons-ipv6.txt" dst-path=blocklist.rsc
/import blocklist.rsc

If the list is a plain text file with one address or CIDR per line, convert it first:

/tool fetch url="https://www.team-cymru.org/Services/Bogons/fullbogons-ipv6.txt" dst-path=blocklist.txt
:foreach line in=[/file get blocklist.txt contents] do={
  /ip firewall address-list add list=blocklist address=$line comment="Team Cymru Fullbogons (IPv6)"
}

Use the list in the firewall

/ip firewall filter add chain=forward src-address-list=blocklist action=drop comment="Team Cymru Fullbogons (IPv6)"
/ip firewall filter add chain=forward dst-address-list=blocklist action=drop comment="Team Cymru Fullbogons (IPv6)"

Schedule the fetch with /system scheduler to keep the list current. Very large lists consume RAM, so check the available memory of your device first.
