  • Information Security Best Practices
    Automate everything. Use a password manager, enable automatic updates, use DNS malware filtering at router level (Free with https://quad9.net ). Source: 6 months ago
  • Firefox has surpassed Chrome on Speedometer
    Depends on your region and what sites you're using. I live in the middle of nowhere far from civilization, and 1.1.1.1 returns terrible IPs for many sites including google.com (which pings at 350-400 ms if you resolve it through 1.1.1.1, but at 90-100 ms if you're using any other resolver). They do it because they block EDNS0 in order to protect your privacy or something like that. So I use 8.8.8.8 and 9.9.9.9 in... - Source: Hacker News / 10 months ago
  • 96 ms to a DNS server OK?
    9.9.9.9 is run by Quad9. They’re more privacy oriented, afaik. Source: 11 months ago
  • University wifi
    Ask your university support desk? You can also try alternative DNSsuch as https://quad9.net . Source: 12 months ago
  • is this dns hijacked?
    Yeah I don't trust ISP DNS, they can see your traffic and dns requests. Using a more privacy dns server like Cloudflare https://1.1.1.1/ or Quad9 https://quad9.net/ are good and free. Source: about 1 year ago
  • DoH Cloudflare changed from dns-cloudflare.com?
    I just realized that I changed my DNS host around 6 months ago. I now use Quad9 -- they support DoT. I just neglected to configure my P7P to use it. Their provider hostname is: dns.quad9.net. Source: about 1 year ago
  • How reliable are obfuscated servers?
    In the meantime, just get yourself a VPS host somewhere and enable SOCKS5 proxy via SSH (ssh -D 8888) Configure your apps/clients to use SOCKS5 proxy on 127.0.0.1 and port 8888. And configure your clients to use Quad9 as a DNS over HTTP (DoH) or similar DNS tricks. And you're basically done. Now those clients/apps using this "proxy" makes the Internet traffic between you and your SSH server look like just a... Source: about 1 year ago
  • Is RARBG still up? DNS error when trying to access.
    I did some probing. I can't resolve rarbg.to with DNS servers 8.8.8.8 (Google), 4.2.2.3 (Level3), or 1.1.1.1 (Cloudflare), but 9.9.9.9 (Quad9) resolves OK as does Firefox's DNS-over-HTTPS enabled using CIRA Canadian Shield. who.is also shows the authoritative DNS is functional. Smells like coordinated blocking by big tech companies to me. That's just speculation, of course. Source: about 1 year ago
  • How to know if a website is safe?
    - You can change your DNS provider to https://quad9.net/. Quad9 blocks suspicious websites. Source: about 1 year ago
  • Internet extremely slow when not connected to VPN
    I've tried a number of things from uninstalling the VPN, clearing DNS, trying to use quad9.net dns, uninstalling and reinstalling network drivers, but nothing has worked. I'm starting to think it has something to do with Verizon or the router, but I really don't know nor am I an expert at this sort of thing. Source: about 1 year ago
  • I would love some help with this issue i have regarding my ipv6
    Hey, dunno if you're still looking for help on this, but there's a multicast filtering option on some wireless access points, that mess with IPv6. Also, overall slowness could be associated with a bad upstream DNS: using something like quad9.net might help (I dunno offhand if the ISP does any special filtering that would require its DNS). Source: over 1 year ago
  • Anti Phishing
    There's already competition in the space, you would need to prove that you're better than quad9.net, Google's safe browsing that's built in, something like Password Alert, and most VPNs offer some safety features. Source: over 1 year ago
  • Deco homeshield subscription benefits?
    Quad9 website with excellent information on their service HERE. They’re based in Switzerland which has extremely strict privacy laws, and Quad9 protects your privacy too with no logs, etc., while blocking malware, phishing, dangerous sites, etc., before they even hit your network. They’re also incredibly quick, faster for me than Google DNS or Cloudflare. Source: over 1 year ago
  • External Antenna 2 or 1
    Until TMHI, I had kept IPv6 disabled on everything without exception, out of a sense of safety, because until recently I knew of no Internet security blacklists for IPv6. But quad9.net has a good working DNS for all, with security blacklisting. So once I discovered that TMHI does IPv6 much faster, I set DNS on Windows and Linux to quad9.net, and enabled v6 on everything. Very nice indeed. And also essential to... Source: over 1 year ago
  • Game has been out for 10 years and this is still not fixed. No truck-, map-, tyre- whatever-mods.
    This might be a longshot, but have you tried a different DNS resolver? If you're using the one from your ISP, I'd suggest switching to something more reliable since they tend to be rather flaky at times. Quad9 is a good option. Source: over 1 year ago
  • [Q] Does the "buy an raspberry pi, configure it, and install pihole"-pdf still exist?
    Cloudflare is a trustworthy company (generally) but I've pivoted over to Quad9 because its filtered lists are surprisingly effective and it's actually approved by Apple to issue DNS over HTTPS certificates. This means that I can have Quad9 doing DNS over HTTPS on my phone regardless of data *or* WiFi. Source: over 1 year ago
  • New IT Manager looking for some advise from seasoned and wise admins
    Easy win is add quad9.net to their internal DNS forwarders. Or put Umbrella on every machine. Source: over 1 year ago
  • Help troubleshooting DNS Leak (pfSense + ExpressVPN + pfBlockerNG)
    I have two DNS servers setup, 9.9.9.1 and 149.112.112.11 (quad9.net). For both DNS servers I've setup the 'Gateway' dropdown to 'WAN_DHCP'. Source: over 1 year ago
  • What are the benefits of changing DNS provider without DOH or DOT?
    Their website states that they “protect against a wide range of threats such as malware, phishing, spyware, and botnets”. Source: almost 2 years ago
  • Sophia's Privacy Guide for Eggs🏳️‍⚧️🥚
    For technologically savvy parents that snoop on your internet traffic... - ...off-device with some sort of router configuration or parental controls through your cellular provider, use a VPN*. If someone ever notices and asks you why you are using a VPN, just say you heard it was good for your privacy. You don't have to mention Reddit at all. If you are on iOS and use iCloud you might be able to use Apple's... Source: almost 2 years ago

    Set wired address, gateway and then DNS manually to https://quad9.net to get out of the update loop. Source: almost 2 years ago
