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

VERSION

    version 0.27

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
    &lt;https://github.com/mikegrb/Net-Abuse-Utils/issues/9#issuecomment-24387435&gt;.

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_all_asn_info ( IP )

    Returns a reference to a list of listrefs containting ASN(s),
    Network,Mask, CC code, RIR, and modified date fall all networks
    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 future,
    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::XS
