What I found: whois.nic.co doesn’t resolve (NXDOMAIN) https://rdap.centralnic.com/co/ returns 404 .CO isn’t listed in the IANA RDAP bootstrap file https://deployment.rdap.org/ shows no RDAP deployment for .CO So … Read More “.co WHOIS and RDAP return no data, anyone know what’s going on?” »
Hello! I am at my wits’ end! I tried logging to cloudfare, and it says that since they suffered a hack that every user must change their password, and they sent an email to change it.

I am sharing my experience of using both Popular Private DNS on mobile, using similar blocklists on both , Hagezi, OISD, and native. Somehow AdGuard is blocking more tracking Queries for me than NextDNS , Although both are great, and performs almost same in ad blocking but in other means AdGuard is slightly ahead.

I am currently using a Private DNS on Android (provided by AdGuard for personalized ad and content blocking). My question is: 1.

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. About 1% of them fail due to HandshakeException WRONG_VERSION_NUMBER. So TLS is failing somewhere. Connections logs show these users are making requests on port 443 but with no TLS version!
