Hi Andreas, The mailto URL scheme does not have any host component as per. its different RFCs it is composed of: - a scheme component : mailto - a path component containing a list of email addresses separated by commas (as per your example) - and a query component representing the email optional headers info
As such the WHATWG and the RFC3986 interpretation will all return null because there's simply no host to describe.
