[PLUG] Assigning a name to local machines

[Smith, Cathy]

That does raise the question if the DNS name servers are configured.  That used to be in the /etc/resolv.conf, but not for some of the newer OS such as Ubuntu 18.04.

If your router can answer dns request ( many routers run dnsmasq service ) then you could have local name resolution working on all machines just by pointing to your router for Dns.

If your router does that - just configure it that it hand out its own IP as Dns during DHCP. You should also configure all the PCs not to change their names by DHCP unless you want that. After that names should work for all machines using DHCP for IP assignment.

The advantage here is that you do not have to hand maintain list of all your machines and their IPs on all host all the time. If you use DHCP IPs change every time you reboot/update router.
