    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

    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: 12 months ago

  • Tunneling Wikipedia through WhatsApp to (maybe?) get around WiFi restrictions
    Many years ago (2012) Delta inflight wifi would allow DNS queries out without paying. Being a very frequent flyer I used to run an ip-over-dns tunnel using Iodine[1]. It was slow but worked. I wonder if they’ve blocked that hole yet. [1] https://code.kryo.se/iodine/. - Source: Hacker News / almost 2 years ago
