NAME

dnsblcheck - Command-line tool for checking IP addresses against DNSBLs.

SYNOPSIS

dnsblcheck ip_address dnsbl1 [dnsbl2...]

DESCRIPTION

Given an IP address and a list of DNSBL zones, dnsblcheck checks each zone for the IP address and prints a list of hits.

Each dnsbl entry is either a simple domain name (for example, zen.spamhaus.org) or a domain:type:data triple (for example, zen.spamhaus.org:match:127.0.0.4 or dnsbl.tld:mask:8). See the Net::DNSBL::Client documentation for details about match and mask zones.

EXIT VALUE

The program's exit value is the number of DNSBLs that were hit.
