Hi, does anyone have experience with the Diamond IP product of Cygna Labs? Would you recommend it? I think there is a lack of documentation/reviews of the product, so i would be happy if somebody can share their experience with it.

Changing default DNS breaks everything.

I’m using internet connection from my local provider. For some reason I changed the default DNS in my macos machine from default to 8.8.8.8 (also tried 1.1.1.1) and suddenly I cannot access any website youtube, fast . com .. nothing. Intrestingly its different from internet not working because when I type in url the loader … Read More “Changing default DNS breaks everything.” »

Looking for feedback: what’s the most annoying part of managing your domain portfolio?

Hey everyone, I’ve been spending the past months building a domain portfolio manager called UnifyDom. It lets you centralise your domains from multiple registrars, track renewals, and compare costs. I know there are already a few tools out there, but I still see people using spreadsheets or juggling dashboards. I’m trying to understand what’s still … Read More “Looking for feedback: what’s the most annoying part of managing your domain portfolio?” »

Geo-testing DNS resolvers, proxies a good call?

Got unbound set up at home for recursive queries, but I need to verify how it handles geo-specific resolutions without messing with my actual location. VPNs are clunky for this. Been reading about Residential Proxies to pull IPs from different spots easily. Has anyone scripted this for testing? Any gotchas, like latency killing the results? … Read More “Geo-testing DNS resolvers, proxies a good call?” »

CNAMEs with Different CAA Records

Posted on 10/28/2025 By firstdns

Hey I’ve apparently got a weird one here – wondering if anyone is familiar with CAA where the CNAME and the target have different CAA records on them. I know the general concept is that CAA will follow the CNAME, but I’m hoping for answers for specific scenarios. Specifically: example1.domain.com CNAME > target1.clash.net example1.domain.com CAA … Read More “CNAMEs with Different CAA Records” »

Do I need “custom hostnames” for nameservers if the domain does not use the same nameservers for itself?

Hello, i have the following usecase: I own a domain on Godaddy mydomain.com . mydomain.com uses xxx.ns.cloudflare.com as NS records, both as NS records in the mydomain.com zone and in the .com nameservers, via Godaddy panel -> assign nameservers ( https://www.godaddy.com/help/edit-my-domain-nameservers-664 ). So, both dig mydomain.com NS @xxx.ns.cloudflare.com and dig mydomain.com NS @a.gtld-servers.net return the … Read More “Do I need “custom hostnames” for nameservers if the domain does not use the same nameservers for itself?” »

DNS not working for Internal Lookups on Different Subnetwork

Hi, I’ll be the first to admit I’m a bit of a beginner with DNS, so apologies ahead of time for the noviceness. We have a customer with two subnetworks (192.168.2.0/24) that contains an Active Directory Domain Controller handling DHCP in the same subnetwork that several workstations lie within. We have another subnetwork (192.168.3.0/24) that … Read More “DNS not working for Internal Lookups on Different Subnetwork” »

I bought a used iPad on backmarket, all seems fine EXCEPT every website I visit (Apple.com, Sony.com, etc) says “This Connection is Untrusted.” I’ve erased all content and settings, reset the network settings, verified the time/date is correct, verified there’s no VPN, proxy is off, tried both automatic dns and manual (8.8.8.8). I’m connected to … Read More “Bought Used iPad / All sites untrusted connections” »
