NAME
Mail::SPF::Util - Mail::SPF utility class SYNOPSIS
use Mail::SPF::Util; $hostname = Mail::SPF::Util->hostname; $ipv6_address_v4mapped = Mail::SPF::Util->ipv4_address_to_ipv6($ipv4_address); $ipv4_address = Mail::SPF::Util->ipv6_address_to_ipv4($ipv6_address_v4mapped); $is_v4mapped = Mail::SPF::Util->ipv6_address_is_ipv4_mapped($ipv6_address); $ip_address_string = Mail::SPF::Util->ip_address_to_string($ip_address); $reverse_name = Mail::SPF::Util->ip_address_reverse($ip_address); $validated_domain = Mail::SPF::Util->valid_domain_for_ip_address( $spf_server, $request, $ip_address, $domain, $find_best_match, # defaults to false $accept_any_domain # defaults to false ); $sanitized_string = Mail::SPF::Util->sanitize_string($string); 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"). SEE ALSO
