ℹ️ About This Blocklist

GBUDB scores IPs on long-running behaviour rather than individual incidents. The "truncate" zone is the high-confidence slice: IPs whose score has stayed bad for long enough that GBUDB recommends rejecting them outright.

What a Listing Means

GBUDB's rolling score for this IP has stayed in the bad range. It reflects months of sending pattern, not a single complaint.

🔢 DNSBL Return Codes

When listed, the DNSBL returns one of these 127.x.x.x addresses. The specific code indicates the reason for the listing.

Return IP Meaning
127.0.0.2 Listed in the GBUDB truncate zone (sustained bad reputation)

⏳ How Listings Clear

There is no removal form. GBUDB scores recover on their own once the sending pattern cleans up: keep the IP quiet and the score drifts back. If you believe the score is wrong, raise it with the operator (ARM Research Labs, [email protected]).
