I am using Vmware player 15 and have 3 guest hosts (A,B,C) with NAT configuration. A is configured as DNS server (Centos 7) - ip address 192.168.136.11 - whereas B and C are DNS clients (Ubuntu 18.04 Desktop) - ip addresses 192.168.136.12, 192.168.136.13.
When I try to ping C from B or B from C using FQDN of C and B respectively I am getting the following error: B.example.com: Temporary failure in name resolution or C.example.com: Temporary failure in name resolution
Any explanation ? Please help
