IP blocklist check
Check whether an IP address is flagged on blocklists and threat databases — across 250+ feeds at once (Spamhaus, StopForumSpam, Tor exits and more). If an IP is listed, email, banks, marketplaces and websites may block you or show captchas.
A clean IP means a dedicated IP
Shared VPN IPs are used by thousands of people — they quickly end up on blocklists, and you get captchas, blocks and bank rejections. vpn.how gives you a personal server with a clean dedicated IP that is yours alone — no neighbours ruining its reputation.
Get a clean dedicated IPFrequently asked questions
What does it mean if an IP is blocklisted?
It means the IP address is in a database of addresses seen sending spam or doing suspicious activity. Email services, banks and websites check these lists and may block or limit connections from that IP.
Why do IPs end up on blocklists?
Because of spam, malware activity, compromised devices on the same network — or simply because the IP is used by hundreds of people (as with shared VPNs) and one of them breaks the rules.
Why are shared VPN IPs often listed but a dedicated IP is not?
A shared VPN IP is used by thousands of people: one offender is enough to get the whole IP listed, and everyone suffers. A dedicated personal IP is used only by you, so its reputation stays clean and stable.
How do I remove my IP from a blocklist?
If it is your home/office IP, you can request delisting on the specific list provider site. But it is simpler and more reliable to use a clean dedicated IP that is not shared with anyone.
