Information about DNS and network
When performing a dns leaktest on the website dnsleaktest.com, both my isp dns and verizon wireless dns on cellular, the results I get are the website cannot be reached. However, using a public dns like cloudflare, Google dns, or Quad9, the site works correctly.

OK, it’s been a long time since I had to use bind9 — but as I recall, once installed, I edited the *options file, added my zones, and if named-checkconf said it was OK, it was. Now, if I use a command like (as root): named -d 9 -f It should start in the foreground … Read More “bind9 on Ubuntu 25.04 : No logging” »
Serving 100,000 monthly active users to my API using the subdomain “api.foo.io”. This points via CNAME record to an AWS load balancer.

When using Pairvpn app it does share the private DNS (Adguard or Nextdns) on phone, but directly connecting to phones hotspot it does not. … Read More “Why is computer not using mobile (android) hotspots private DNS setting (AdGuard or NextDNS)?” »
Is a dns not passing the dnssec test per dnscheck.tools a big deal? It passes the valid signature, but fails the invalid, expired, and missing signature tests per dnscheck.tools. Is this something I shouldn’t use? I know all the public ones passing like cloudflare, google dns, and Quad9, but my isp dns does not. submitted … Read More “dns not passing dnssec?” »
I am new to this subreddit having only just found it. I hope my question is suitable for this forum. It concerns the operation of DNSSEC. Our DNS infrastructure is outsourced to a company who are helpful in making changes are not so good at helping troubleshoot. So we are diagnosing things with no access … Read More “DNSSEC.
