IP reputation check
Checks one address against the blocklists mail providers and abuse desks genuinely consult, and links you straight to the removal form for anything that has it. No account. We are also not going to ask for your email before showing you the answer.
One IPv4 address at a time. The portal scans whole ranges on a schedule and files the delistings for you.

One address at a time only gets you so far.
Reputation is really a property of a whole range. The Prefixx portal scans every address in the
ranges you hold on a schedule, scores each range, tracks how it moves, and tells you the moment a
listing shows up. Where the listing did not come from your own traffic, our team files the removal
and confirms it came off. That runs at no charge for leased space and after a transfer.
