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.
Download a new Public Suffix List file from mozilla and update the installed file with the new copy.
Determine if a DNS Resource Record of the specified type exists at the DNS name provided.
Returns a (cached) Net::DNS::Resolver object
Set the Net::DNS::Resolver object to be used for lookups
Determines if the supplied IP address is a valid IPv4 or IPv6 address.
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.
