DNS resolver

A DNS resolver resolves hostnames to IP addresses by querying DNS servers according to
an ordered list. The list of DNS servers is compiled using either DNS servers entered manually
by the user, or DNS servers gathered automatically by means of DHCP or PPP protocols, or
both.
The user can also optionally aid the DNS resolver by specifying a list of domain names that
the DNS resolver adds as a suffix to non-Fully Qualified Domain Name (FQDN) names, to help
resolve them to an IP address.
The DNS resolver feature is intended to provide a backup mechanism for VPN hubs using
DNS. For more information about VPNs on the Branch Gateway, see
page 479.
