Can I set DNS as 192.168.2.1 on router & systems?
So why my net doesn't works fine i.e random page cannot be displayed (if DNS on adapter set to obtain automatically & on router automatic from ISP)?Since your adapters obtain DNS automatically like mine do, all that will show is the gateway as it's the one giving you the DNS. If you set a manual DNS (on your computer), it will show exactly what DNS your using.
OpenDNS manually set on a computer will show this with the ipconfig /all command. Even if you set a manually DNS on your router, it will still say the same. Easiest and best way to get your real DNS servers is this site: IP/DNS Detect
This site is actually very useful to make sure your VPN/WebRTC isn't leaking your IP but it's also great for seeing your DNS as VPN (well most of them anyway) will change your DNS to one of their choice to increase security/anonymity.
It will work fine because your router is set to automatic (getting DNS from ISP which they themselves run) and your computer will get that DNS from the router due to it being on automatically obtain which will allow it to obtain from modem/router depending on what your computer is attached to. In this case, it's the router.So why my net doesn't works fine i.e random page cannot be displayed (if DNS on adapter set to obtain automatically & on router automatic from ISP)?
