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

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-243874
    35&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_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
