This should contain a name like <literal>Lennart's Laptop</literal> which is useful to present to the user and does not suffer by the syntax limitations of internet domain names.

Example: if this value is <literal>Lennart's Computer</literal> an Internet host name of <literal>lennarts-computer</literal> might be a good choice.
