usually the same as the assigned DNS Name. It is always the first part of a Fully Qualified
Domain Name and is always one word, with no period. For example, myserver is the host
name in the Fully Qualified Domain Name myserver.mycompany.com.

local DNS servers whenever the product's IP address changes. Check this box to enable the
function.
