Yeah partially, but what I'm missing here are primarily notifications, and perhaps the ability to specify the specific resolvers/nameservers you care about.

And yes, it would periodically check these resolvers/nameservers and maybe compare it with your rules or something like that? And perhaps it would monitor the entire DNS record change history since the time you set it up, so you could then apply some rules to that output and configure notifications on top of that?

I really don't have specific functionality in mind, just something that would solve that issue of me being bottlenecked by the constant checking of DNS records.

Ask HN: Notify about DNS records propagation

Hi there, I always had the pain of constantly dig'ing for a domain, and checking if the new expected IP address (or any other record type really) is finally written and propagated into all relevant resolvers.

So, I was thinking about automating this, wiring it up to email notifications or slack.. And webhooks would be cool - you could do some cool automation with those (chain with issuing a SSL cert)!!

Just wondering if I'm the only one who would pay a few bucks for this, or you guys don't share this pain point at all.

Have a magnificent day!

Show HN: SSL certificate discovery from CT logs

vojtechrichter — Sun, 03 May 2026 12:08:43 +0000

Free tool to discover possibly forgotten subdomains with issued certificates.

Some domains might need to get submitted in a few repeated attempts, since the public CT logs registries are very overloaded, and Tidelock is trying to pick the most accessible one, without caching anything, so the provided report is always up-to-date with live information.

I will be grateful for any feedback regarding this tool, or in general any SSL/DNS related tools you would appreciate in your daily work.

I made this free tool that projects DNS record propagation in name servers across the globe. I would be thankful for any feedback to make this tool better, and more effective for everyone. Currently only support A records.

Very relatable, and I agree to some extent. At least part of the things you're pursuing should be fun to you, because if they're not, why even bother?

I've been stuck in this mindset that I need to find a niche people care about, a problem people have, but none of this is gonna get any results (most likely), if you're not passionate about the topic.

So just do what interests you, what you find cool, and the world will adapt.

I have one of these, the only issue is that you can't lean too much forward, otherwise you're going to fall :D
