THE PROBLEM

By the time the tickets hit,
it's already too late.

You're routing thousands of IPs. The tools that exist check one at a time and charge you for the privilege. So you find out from angry users - sharpening pitchforks in the conference room.

You're flying blind on a CIDR

Per-IP checkers cap the free tier at one IP and want $129/mo after. Useless when you route a /22 - so nobody's actually watching.

One bad neighbor lists your whole /23

"I received an abuse for 1 IP from my /23… and then they blacklisted my whole /23." UCEPROTECT L2/L3 takes the whole range hostage.

No idea why you're listed

Zero clarity around resolving it. Which IP? Which list? Compromised WordPress, open relay, port 25? Hours of manual forensics.

Fix it, get relisted by morning

Delist, then back on within hours because the root cause is still live. And your ISP gives you 30 days before they cut the circuit.
THE SOLUTION

Watch the whole block. Catch it first. Know why.

Continuous monitoring across your entire range, real alerts the second something lists, and the diagnosis to make a delisting actually stick.

Which IP, which list

Pinpoints the exact address and listing — no guessing across the block.
