I am experiencing issues getting to somewebsites, but not all. We are on NBN (FTTN) I believe. I have our router (Archer 1600v v1) configured to use 203.12.160.35 and 203.12.160.36 as primary and secondary DNS Servers and have had no issues till yesterday. Our network adapters are set to for automatic IP address assignment and to get DNS Servers from the router. I've changed one machine to use Google DNS Server addresses (8.8.8.8 and 8.8.4.4) and that has seemed to resolve the issue for this machine.  I believe our router has the most current firmware.   Could you please advise whether there is an issue with your DNS Servers or whether there is a problem at our end, and if so, where I should look   Thank you. ...
