🚫 UCEPROTECT L2
Guide to the UCEPROTECT L2 range-level blocklist: why entire subnets get listed and how to handle collateral listings.
IP Blocklist (RBL)
dnsbl-2.uceprotect.net
ℹ️ About This Blocklist
UCEPROTECT Level 2 lists entire IP ranges (typically /24 subnets) that contain too many individually-listed IPs. Affects all IPs in the range even if only a few are spamming.
What a Listing Means
Your IP's subnet (/24 range) contains multiple spam sources. Your IP may be collateral damage from neighbours in the same hosting range.
🔢 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 UCEPROTECT L2 (range-level) |
✅ How to Request Delisting
L2 listings are based on the aggregate reputation of an IP range. If you're collateral damage, contact your hosting provider — the range needs to be cleaned up. Paid express delisting is available.
