UCEPROTECT Level 2
Blocks neighbouring IPs of Level 1 listings — collateral by netblock.

What it lists
Level 2 lists netblocks where multiple neighbours appear on Level 1. Senders on shared infrastructure can be caught by their neighbours' behaviour.
Who gets listed
Netblocks with concentrated Level 1 activity from multiple IPs.
Reputation impact
Generally low. Most mainstream providers ignore Level 2; the impact is on senders whose recipients use UCEPROTECT-tuned MTAs.
How to delist
Move to a clean netblock, or escalate with your hosting provider to clean up neighbours. Paid expedited removal exists; otherwise wait for the netblock to clear.
