    Sporadic website connectivity (possibly ipv6 issues)

    I'm really not sure how else to describe the problem. I have a wired connection through some powerline adapters, my wifi is off. It seems that I can connect to some websites, but others I cannot. For example, tenforums.com seems to have no problem. nodejs.org is constantly timing out. The weird thing, if I visit nodejs.org through a free proxy service, then the website finally renders in my browser (edge).

    For what it's worth, I believe something about ipv6 may be the issue... but I'm not a networking guy and don't know how to start diagnosing the problem. Any help is appreciated.

    Important Internet Protocol version 6 (IPv6) is a mandatory part of Windows Vista and later versions of Windows. We do not recommend that you disable IPv6 or its components.

    I have read that disabling ipv6 is discouraged by Microsoft. And that is just a hunch I have, that ipv6 is the problem. I'd first like to know for sure if that is the issue, so my first question would be how do I determine that? Again, not a networking guy, so setting DNS is something I'm not familiar with. Thanks for the suggestions.

    The link you provided didn't work for me because I have windows 10, which they don't have instructions listed for apparently. I googled changing Windows 10 DNS and managed to use Google's DNS servers ( & and it looks like I can access the nodejs.org domain without issue now.

    I'm not a huge fan of running off with fixes without understanding what happened. It seems that the only thing that changed was switching to Google's DNS server from what I was using by default (I'm assuming my ISP's?). Even if that is the case, I'd like to know what happened and why if someone would like to chime in. I'll leave this as unresolved until then.

    Samuria, thanks for helping me find a solution!
