What is DROP?
Don’t Route Or Peer (DROP) is an advisory “drop all traffic” list.
DROP is a tiny subset of the SBL which is designed for use by firewalls and routing equipment.
- The DROP list will not include any IP space allocated to a legitimate network and then reassigned – even if reassigned to confirmed spammers.
- DROP does include netblocks that have been hijacked or are leased by professional spam or cyber-crime operations and are used for dissemination of malware, trojan downloaders, botnet controllers, etc.
- DROP is composed of direct allocations from ARIN, RIPE, APNIC, LACNIC, or other Regional Internet Registries and “portable allocations” (known as “PI”) from RIPE.
Spamhaus strongly recommends the use of DROP by Tier-1 and backbone networks. Consulting the DROP list webpage when someone asks you to route some suspicious IPs can help avoid customers that will cause big problems on your network.
