    Viva Italia? (You mentioned ipleak.net)
    uBlock has a cool setting, "Prevent WebRTC...".
    Not a chrome guy, but a CanvasBlocker Add-On might be something worth checking out?

    GRC's DNS Benchmark is a cool tool... and another test you might want to check out (if you haven't already) is GRC's DNS Spoofability. I bookmark it and run it out of habit every start-up, or any VPN proxy/IP change. "Stuck Bits" make me frown. :)

    Thanks for the additional info. I will definitely look into those extra tools. I noticed uBlock has the WebRTC feature built in which is nice. I was using the AdGuard extension until recently due to performance issues but I think it was more related to my VPN's DNS than anything. Extension wise I think uBlock is more robust but slightly more complicated to use than AdGuard. But AdGuard's system level filtering on their Android and Windows applications is nice to use because it is system wide filtering. However I no longer use it thanks to a similar feature being integrated into my VPN client in the last year or so.

    Question... can too many DNS Servers (w/in your machine's Adapter DNS Servers)... can too many be a bad thing? Or, go for it?

    Reason for the question... I loaded up my machine's Adapter DNS with many OpenNic no logging (hunted around for reputable Netherlands servers as I like using Netherlands VPN proxies)... and then threw in a handful of other reputable DNS Servers (including my VPNs -BTW, no redundant servers on Router vs. Adapter).

    After I loaded up Adapter DNS Servers, and running a speedtest ( https://speedof.me/ ), the speedtest results were insanely fast. I did it recently, and I think general connectivity speeds are up (but my HTML5 speedtest results are 2-3x's faster now when I'm using VPN -no matter which proxy, US, CA, NL, et). The Adapter DNS servers are in no particular order -i.e., not optimized using DNS Benchmark, I just have a sh*tload of servers in there.

    Surprisingly, there are few hits for a web-search "how many DNS servers are overkill" or whatnot. Thanks in advance for your time & any help!

    I reckon your VPN already uses Optimal DNS server(s). I recommend you use only 1 DNS service with Primary and secondary DNS address.

    It depends on the implementation for the use of the DNS servers listed, AFAIK there is no round robin or "going through the list" sharing the load across the entered DNS servers in Windows Client OS's.

    Typically the Primary DNS server address is used until a timeout occurs in getting a response back, then the Secondary is tried, etc going to each one in the list in order as each DNS server tried times out in it's response.

    There wouldn't be any speed up except as experienced from changing the Primary DNS server to a faster / better latency one.

    Now, that's true of client OS's in general, but other server or network appliance OS's are designed to make use of a larger list of DNS servers and use load balancing across them in various algorithmic ways.

    Use DNS Policy for Application Load Balancing
    https://docs.microsoft.com/en-us/windows-server/networking/dns/deploy/app-lb

    That's really not a recommendation to use for client use, as you shouldn't have a use case requiring implementation, but it's fun to know about anyway. :)

    Makes total sense, but I'm curious why https://speedof.me/ test results indicate better connectivity (like markedly faster -both DL & UL)? It's hard to tell if pages load more quickly or general connectivity has improved (as I already have decent speeds)... so I'll take your guys' advice & drop 10 OpenNic servers. Much obliged! :)

    Thanks for the link! I shall check it now. Thanks hmscott & Vasudev!

    I sometimes used added DNS servers as a notation method for the DNS servers I was also interested in at the time. Keeping a longer list of DNS servers in the configuration file(s) was a good reference should I need it quickly later.

    If I start having DNS related issues I could pop the failing one(s) off the list and fall back to the others I entered the last time I researched so I can quickly become functional again, until I have time to research better DNS servers of the current time.

    This was true of client machines, local DNS servers, and other servers.

    I haven't had to do that for a very long time, the internet is much more reliable now. :)

    The problem for me with cloudflare DNS is that in Portugal at least he blocks\breaks resolving some websites.
    When compared with other DNS (97% of free) is realy fast

    Just about my experience when I was travelling in Germany. Cloudfare did not work in a train (DB) at all and it did not help me that I had other secondary DNS server (Open DNS). Well, it took a while before I understood that I have a problem with Cloudfare applied for my laptop … :)
