@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.

nisd_resolv
rpc.nisd_resolv(1M) System Administration Commands rpc.nisd_resolv(1M)
NAME
rpc.nisd_resolv, nisd_resolv - NIS+ service daemon
SYNOPSIS
rpc.nisd_resolv [-v | -V] [-F [-C fd]] [-t xx] [-p yy]
DESCRIPTION
rpc.nisd_resolv is an auxiliary process which provides DNS forwarding service for NIS hosts requests to both ypserv and rpc.nisd that are
running in the NIS compatibility mode. It is generally started by invoking rpc.nisd(1M) with the -B option or ypserv(1M) with the -d
option. Although it is not recommended, rpc.nisd_resolv can also be started independently with the following options.
This command requires that the /etc/resolv.conf file be setup for communication with a DNS nameserver. The nslookup utility can be used to
verify communication with a DNS nameserver. See resolv.conf(4) and nslookup(1M).
OPTIONS
-F Run in foreground.
-C fd Use fd for service xprt (from nisd).
-v Verbose. Send output to the syslog daemon.
-V Verbose. Send output to stdout.
-t xx Use transport xx.
-p yy Use transient program# yy.
