No, no need to change it.
It explains why "ping smb" was able to get an IP address.
I'm pretty sure that you have the IP address of the router in your /etc/resolv.conf.
So, the DNS server your using is the same as the DHCP server. In this case, when the
DHCP server supplies
a lease it also adds a DNS record.
That didn't dawn on me since all of my servers use static IPv4 and IPv6 addresses and
use a different DNS server
than the router.

I use hosts for convenience, as you can see it is not up to date:
[bobg@WS1 ~]$ cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4
localhost4.localdomain4
::1 localhost localhost.localdomain localhost6
localhost6.localdomain6
192.168.50.57 WS1 ws1
192.168.2.179 ws2 WS2
192.168.50.32 nfs NFS
192.168.50.149 smb SMB
And 192.168.50.1
[bobg@WS1 ~]$ cat /etc/resolv.conf
# Generated by NetworkManager
192.168.50.1 is the router, as you observed earlier I just went with the
'.50' to differentiate between the system, Dish Network also added a
10.1.something a while back ... There are two Ethernet ports on the
Viasat modem and I cold use a third one, I have the Dish Network router
turned off, have had no complaints yet. I guess it might work to add
another switch between the modem and a router, I have not tried that
yet? Presently the other routers turned off so they are not contributing
uncertainties.
