DESCRIPTION
       Mail::SPF::Util is Mail::SPF's utility class.
   Class methods
       The following class methods are provided:
       hostname: returns string
           Returns the fully qualified domain name (FQDN) of the local host.
       ipv4_address_to_ipv6($ipv4_address): returns NetAddr::IP; throws
       Mail::SPF::EInvalidOptionValue
           Converts the specified NetAddr::IP IPv4 address into an IPv4-mapped
           IPv6 address.  Throws a Mail::SPF::EInvalidOptionValue exception if
           the specified IP address is not an IPv4 address.
       ipv6_address_to_ipv4($ipv6_address): returns NetAddr::IP; throws
       Mail::SPF::EInvalidOptionValue
           Converts the specified NetAddr::IP IPv4-mapped IPv6 address into a
           proper IPv4 address.  Throws a Mail::SPF::EInvalidOptionValue
           exception if the specified IP address is not an IPv4-mapped IPv6
           address.
       ipv6_address_is_ipv4_mapped($ipv6_address): returns boolean
           Returns true if the specified NetAddr::IP IPv6 address is an
           IPv4-mapped address, false otherwise.
       ip_address_to_string($ip_address): returns string; throws
       Mail::SPF::EInvalidOptionValue
           Returns the given NetAddr::IP IPv4 or IPv6 address compactly
           formatted as a string.  For IPv4 addresses, this is equivalent to
           calling NetAddr::IP's "addr" method.  For IPv6 addresses, this is
           equivalent to calling NetAddr::IP's "short" method.  Throws a
           Mail::SPF::EInvalidOptionValue exception if the specified object is
           not a NetAddr::IP IPv4 or IPv6 address object.
       ip_address_reverse($ip_address): returns string; throws
       Mail::SPF::EInvalidOptionValue
           Returns the "in-addr.arpa."/"ip6.arpa." reverse notation of the
           given NetAddr::IP IPv4 or IPv6 address.  Throws a
           Mail::SPF::EInvalidOptionValue exception if the specified object is
           not a NetAddr::IP IPv4 or IPv6 address object.
       valid_domain_for_ip_address($server, $request, $ip_address, $domain,
       $find_best_match = false, $accept_any_domain = false): returns string
       or undef
           Finds a valid domain name for the given NetAddr::IP IP address that
           matches the given domain or a sub-domain thereof.  A domain name is
           valid for the given IP address if the IP address reverse-maps to
           that domain name in DNS, and the domain name in turn forward-maps
           to the IP address.  Uses the given Mail::SPF::Server and
           Mail::SPF::Request objects to perform DNS look-ups.  Returns the
           validated domain name.
           If $find_best_match is true, the one domain name is selected that
           best matches the given domain name, preferring direct matches over
           sub-domain matches.  Defaults to false.
           If $accept_any_domain is true, any domain names are considered
           acceptable, even if they differ completely from the given domain
           name (which is then effectively unused unless a best match is
           requested).  Defaults to false.
       sanitize_string($string): returns string or undef
           Replaces all non-printable or non-ascii characters in a string with
           their hex-escaped representation (e.g., "\x00").
