An opened discussion, feel free to share your thoughts!!! I have 2 ISPs each of them with separate routers Router 1 : 192.168.0.1 : ISP 1 Router 2 : 192.168.1.1 : ISP 2 I have this connected to a D-link switch. From the switch I have 14 systems connected. via lan . I have 10 systems on ISP 1 and 4 systems on ISP 2 (all with static Ips) Among these 10 systems I have 3 that are working on the ISP 2 DNS and the rest on ISP 1 DNS. Question: how do I get all the 10 systems on the same DNS in spite of assigning them with the same DNS. Note I have also assigned the advanced IP with 192.168.1.1 . Tricky but not sure if this is clear enough. Share your thoughts.
