Is this domain
on a blocklist?
Type a domain, yours or one you are thinking of buying. We ask the free spam and malware lists and tell you straight.
About the domain check.
What does this check?
Spamhaus, SURBL and URLhaus, three blocklists that track spam, phishing and malware, plus the Wayback Machine, which shows whether the name had a website before. A list that does not answer is shown as skipped, never as a pass.
Why does it matter for a link in bio?
Instagram reads the link in your bio. A domain that was used for spam or malware before it was dropped can carry that history to you, so it is worth knowing before you put your name on it.
Is it free?
Yes, 5 checks an hour, no account. Signed in, the domain wizard has a Scan button on every name, and a name on a blocklist is not sold.
Do you keep what I check?
The answer is kept for an hour so the same name is not looked up twice, with nothing about who asked. Your internet address is counted for the hour to apply the limit, and that count is then cleared.
