Registered Domainedit

The registered_domain processor reads a field containing a hostname and then writes the "registered domain" contained in the hostname to the target field. For example, given www.google.co.uk the processor would output google.co.uk. In other words the "registered domain" is the effective top-level domain (co.uk) plus one level (google).

This processor uses the Mozilla Public Suffix list to determine the value.
