NAME ^

Net::Abuse::Utils - Routines useful for processing network abuse

VERSION ^

version 0.23

SYNOPSIS ^

    use Net::Abuse::Utils qw( :all );
    print "IP Whois Contacts: ", join( ' ', get_ipwi_contacts($ip) ), "\n";
    print "Abuse.net Contacts: ", get_abusenet_contact($domain), "\n";

DESCRIPTION ^

Net::Abuse::Utils provides serveral functions useful for determining information about an IP address including contact/reporting addresses, ASN/network info, reverse dns, and DNSBL listing status. Functions which take an IP accept either IPv6 or IPv4 IPs unless indicated otherwise.

CONFIGURATION ^

There is a @RESOLVERS package variable you can use to specify name servers different than the systems nameservers for queries from this module. If you intend to use Google's nameservers here, please see This issue on GitHub for a note of caution.

FUNCTIONS ^

The following functions are exportable from this module. You may import all of them into your namespace with the :all tag.

get_asn_info ( IP )

Returns a list containing (ASN, Network/Mask, CC code, RIR, modified date) for the network announcing IP.

get_peer_info ( IP )

IPv4 Only. Returns an array of hash references containing (ASN, Network/Mask, CC code, RIR, modified date) for the peers of the network announcing IP.

get_as_description ( ASN )

Returns the AS description for ASN.

get_as_company ( ASN )

Similiar to get_as_description but attempts to clean it up some before returning it.

get_soa_contact( IP )

Returns the SOA contact email address for the reverse DNS /24 zone containing IP.

get_ipwi_contacts( IP )

Returns a list of all email addresses found in whois information for IP with duplicates removed.

get_rdns( IP )

Returns the reverse PTR for IP.

get_dnsbl_listing( IP, DNSBL zone )

IPv4 Only. Returns the listing text for IP for the designated DNSBL. DNSBL zone should be the zone used for looking up addresses in the blocking list.

get_ip_country( IP )

Returns the 2 letter country code for IP.

get_asn_country( ASN )

Returns the 2 letter country code for ASN.

get_abusenet_contact ( domain )

Returns the abuse.net listed contact email addresses for domain.

is_ip ( IP )

Returns true if IP looks like an IP, false otherwise.

get_domain ( IP )

Takes a hostname and attempts to return the domain name.

get_malware ( md5 )

Takes a malware md5 hash and tests it against http://www.team-cymru.org/Services/MHR. Returns a HASHREF of last_seen and detection_rate.

DIAGNOSTICS ^

Each subroutine will return undef if unsuccessful. In the furture, debugging output will be available.

CONFIGURATION AND ENVIRONMENT ^

There are two commented out lines that can be uncommented to enable Memoize support. I haven't yet decided whether to include this option by default. It may be made available in the future via an import flag to use.

DEPENDENCIES ^

This module makes use of the following modules:

Net::IP, Net::DNS, Net::Whois::IP, and Email::Address

BUGS AND LIMITATIONS ^
