       | nameserver and DNS resolver is this:
       | 
       | nameserver is a term used by DHCP and host resolver to be the
       | server that provides a fully resolved (one that did all the
       | resolving or asked others to do some resolving) upon receiving a
       | DNS request before sending the final answer to the requestor
       | (often the host via resolver library (as often guided by
       | /etc/resolve.conf). The nameserver can be a forwarder and by its
       | stated function not have a recursive mechanism. Nameserver is
       | more about the first step for a host to obtain an answer to its
       | query.
       | 
       | DNS resolver is not the common term to use but refers to a
       | generic DNS server configured to do a partial or full recursive
       | (depending on whether they also have some primary zone(s)
       | locally) with a goal to contact an authoritative server for each
       | zone (parts of the domain name separated by a period). A DNS
       | resolver would not necessarily be the first server that a host
       | would request.
       | 
       | Of course, caching might provide one of its zone answer sooner,
       | if enabled and encountered an answer previously within its
       | expiration period.
       | 
       | Any error, typos, mistakes are mine and mine alone. This is my
       | off-the-cuff answer.
