Hey how are you.
I'm a Solaris admin but I have been doing a lot of RHEL administration lately. No matter what UNIX or Linux distro I have work with, the /etc/resolve.conf file is used to point a server to the DNS server. If you don't want to use a editor like vi, then use this command.

Example your DNS server's IP is 10.0.0.1
Code:
echo nameserver 10.0.0.1 >>  /etc/resolve.conf

This should be what you see;
Code:
cat /etc/resolve.conf 
nameserver 10.0.0.1

You can also use the GUI.
System --> Administration --> Network
you can edit the the interfase in this GUI.

I hope this helps

dnsextd(8)						    BSD System Manager's Manual 						dnsextd(8)

NAME
dnsextd -- BIND Extension Daemon SYNOPSIS
dnsextd DESCRIPTION
dnsextd is a daemon invoked at boot time, running alongside BIND 9, to implement two EDNS0 extensions to the standard DNS protocol. dnsextd allows clients to perform DNS Updates with an attached lease lifetime, so that if the client crashes or is disconnected from the net- work, its address records will be automatically deleted after the lease expires. dnsextd allows clients to perform long-lived queries. Instead of rapidly polling the server to discover when information changes, long-lived queries enable a client to indicate its interest in some set of data, and then be notified asynchronously by the server whenever any of that data changes. dnsextd has no user-specifiable command-line argument, and users should not run dnsextd manually. SEE ALSO
mDNS(1) mDNSResponder(8) For information on Dynamic DNS Update, see RFC 2136 "Dynamic Updates in the Domain Name System (DNS UPDATE)" For information on Dynamic DNS Update Leases, see http://files.dns-sd.org/draft-dns-update-leases.txt For information on Long-Lived Queries, see http://files.dns-sd.org/draft-dns-llq.txt BUGS
dnsextd bugs are tracked in Apple Radar component "mDNSResponder". HISTORY
The dnsextd daemon first appeared in Mac OS X 10.4 (Tiger). Darwin June 2, 2019 Darwin
