DNSBL Lookup - check if your IP is blacklisted

DNS Blacklists or DNSBLs are a way to filter spam by using Domain Name Service (DNS) records as a database of IP addresses linked to spamming. Specify an IP address (your current IP is set by default) and press a button to check if IP is blacklisted in DNSBL services. Click on a service name to see more details about it.
