<para>A list of domains which should be resolved using the DNS servers on this link. Each item in the list
should be a domain name, optionally prefixed with a tilde (<literal>~</literal>). The domains with the
prefix are called "routing-only domains". The domains without the prefix are called "search domains" and
are first used as search suffixes for extending single-label host names (host names containing no dots) to
become fully qualified domain names (FQDNs). If a single-label host name is resolved on this interface,
each of the specified search domains are appended to it in turn, converting it into a fully qualified
domain name, until one of them may be successfully resolved.</para>

<para>Both "search" and "routing-only" domains are used for routing of DNS queries: look-ups for host names
ending in those domains (hence also single label names, if any "search domains" are listed), are routed to
