@vbe......no, you are not wrong. Routers get their external ip address from the internet service provider along with DNS service information. When the client requests ip address from the router which commonly also acts as the LAN DHCP server, the router also provides the DNS information to the client also.

In my previous post#3 I was simply looking to "quick fix" a missing DNS configuration but, in practice, on many modern distributions, resolv.conf is redundant in so far as there are often network management software packages that dynamically amend resolv.conf so that the sysadmin is not directly in control of resolv.conf content. Other software on the system may change the content automatically.

RESOLV.CONF(5)							File Formats Manual						    RESOLV.CONF(5)

NAME

       resolv.conf - Domain Name System resolver configuration

SYNOPSIS

       /etc/resolv.conf

DESCRIPTION

       The  /etc/resolv.conf  is used to configure how the host will use the Domain Name System to resolve hostnames to IP addresses.  It may con-
       tain these two lines:

	      nameserver     IP-address
	      domain	     domain-name

       The nameserver entry tells the IP address of the host to use for DNS queries.  If it is set to 127.0.0.1 (which is the  default)  then  the
       local  name  daemon is used that may use the /etc/hosts database to translate host names.  You normally only need a nameserver entry if the
       name server is at the other side of a router.  The default nonamed name server can't look beyond the local network.

       The domain entry tells the default domain to use for unqualified hostnames.  This entry is usually not given in which case  the	domain	of
       the local host is used.

       The long version of this story can be found in resolver(5).

FILES

       /etc/resolv.conf    DNS resolver configuration file.

SEE ALSO

       resolver(5), hosts(5), nonamed(8), boot(8).
