🚫 UCEPROTECT L2
Why UCEPROTECT L2 lists entire subnets, and what to do when a noisy neighbour drags your IP onto the list.
IP Blocklist (RBL)
dnsbl-2.uceprotect.net
ℹ️ About This Blocklist
Level 2 lists whole IP ranges, typically a /24, when too many addresses in that range trip the Level 1 list. Every IP in the range is affected, including the well-behaved ones.
What a Listing Means
Your /24 has too many spam sources in it. Your specific IP may be clean — you are caught by the neighbours.
🔢 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 (whole-range listing) |
⏳ How Listings Clear
You cannot delist a single IP from L2 on your own. Either move to a cleaner range, push your hosting provider to discipline the spammers in the block, or pay UCEPROTECT for express removal.
