Mail::DMARC::Base(3)  User Contributed Perl Documentation Mail::DMARC::Base(3)

NAME
       Mail::DMARC::Base - DMARC utility functions

VERSION
       version 1.20190308

METHODS
   is_public_suffix
       Determines if part of a domain is a Top Level Domain (TLD). Examples of
       TLDs are	com, net, org, co.ok, am, and us.

       Determination is	made by	consulting a Public Suffix List. The included
       PSL is from mozilla.org.	See http://publicsuffix.org/list/ for more
       information, and	a link to download the latest PSL.

   update_psl_file
       Download	a new Public Suffix List file from mozilla and update the
       installed file with the new copy.

   has_dns_rr
       Determine if a DNS Resource Record of the specified type	exists at the
       DNS name	provided.

   get_resolver
       Returns a (cached) Net::DNS::Resolver object

   set_resolver
       Set the Net::DNS::Resolver object to be used for	lookups

   is_valid_ip
       Determines if the supplied IP address is	a valid	IPv4 or	IPv6 address.

   is_valid_domain
       Determine if a string is	a legal	RFC 1034 or 1101 host name.

       Half the	reason to test for domain validity is to shave seconds off our
       processing time by not having to	process	DNS queries for	illegal	host
       names. The other	half is	to raise exceptions if methods are being
       called incorrectly.
