pul··on Finding services companies via their TXT records
As they should. If a domain name changes hands, the previous owner should have its ownership verification revoked.

Very relatable! I also went through 15 failed projects [1] before going full time on the other two.

Thanks :) They are all generated with Midjourney. This is the prompt I used for one of the images:

You nailed it! Recursion, propagation, registry, registrar, registrant. Naming in the DNS could — ironically — use some work. But it's too late now, I suppose.

Thanks! I appreciate it :)
pul··on NsLookup Learning Center
Ruurtjan from nslookup.io here. I've contracted an ex Azure DNS team member to write up articles about DNS [1] and published it for free. I considered my DNS knowledge okay, but I learned something every article he wrote.

If you want to be better at DNS than >99% of your colleagues for the rest of your career, then invest a single day in reading those.

I'm looking for someone to write articles for https://www.nslookup.io/learning/. You'll need to have hands-on experience working with the DNS. Read a couple of articles to get an idea for the level of expertise needed. I'll prepare briefs with the outline of the article. Get in touch for more info.

I couldn’t find any contact info for you, but if you’d like to do a paid write up on GNS for nslookup.io, please contact me :)
pul··on Show HN: Digany(1) – ANY DNS lookup utility
Ruurtjan from nslookup.io here.

You're using the list of DNS records from the original DNS RFC from 1987. Since then, a lot of new record types have been added: https://www.iana.org/assignments/dns-parameters/dns-paramete... Some of them, like CAA, SRV and AAAA, are used fairly often.

In my case, it must have been intentional. The editor added a line 'Also published here' with the canonical at the bottom of the article.

Ruurtjan from NsLookup.io here. Would love to hear your feedback, since you probably can name a thing or two to improve :)
pul··on How to pick a side project strategically
You've got a couple of options:

1. Ads through Ethical Ads or Carbon Ads. This is what I have with nslookup. It's at $500/month on these volumes: https://plausible.io/nslookup.io

2. An exclusive ad deal with a complementary service. That's what I have with whoismyisp.org. Think about what people are working on when they visit your tool, then find a service that they'll need right after that task.

3. Donations

4. Sell a course. i.e. "DNS for developers" for nslookup.io.

5. Add a paid API. i.e. DNS lookup API for nslookup.io.

6. Add a SaaS that does something similar, but more complex. i.e. monitoring DNS records for nslookup.io.

pul··on How to pick a side project strategically
Hi HN, Ruurtjan from nslookup.io here. Ask me anything.

I'm also happy to give feedback on any side project (idea) you're working on.

I think so too. Thanks :)

In all fairness, Mullvad also shows as 'protected'. I think I'll add a pop-up on hover that explains what 'unprotected' means, and how a VPN helps.
pul··on Ask HN: Developers who switched careers, what are you doing now?
About 7000 people per day [1]. Because they either

- Don't know you can do it from a command line

- Don't bother remembering the order of arguments

- Want to see all record types in one go instead of repeating the command for every record type

- Would like to have the output clearly formatted

- Are currently on mobile

- Would like to see additional ip info for A/AAAA records

- Would like to check responses for multiple recursive resolvers without remembering all their IP's

- Would like to test GEO DNS

What would make it more useful, less parasitic and less slimy?
pul··on Ask HN: Developers who switched careers, what are you doing now?
It's a stale list (checked into git) of the top 1m sites according to alexa.com, back when it was still maintained. Will need to update it to https://tranco-list.eu/ some time.
pul··on Ask HN: Developers who switched careers, what are you doing now?
Yes. I'm on Carbon ads for the first, and I've partnered with NordVPN and ipinfo.io for the second. ~400 USD/month at the moment for nslookup.io. Stats are open: plausible.io/nslookup.io The end game for that site is to partner with a hosting provider or CDN and sell ad space to them exclusively.
pul··on Ask HN: Developers who switched careers, what are you doing now?
Not sure if this is what you mean, but I 'switched' from an ML consultancy to entrepreneurship. I now build and market my own projects ([1], [2]) and try to gain enough ad revenue to replace my former salary.

Started 1.5 months ago, and enjoying every minute of it! No longer occupying my mind with corporate power dynamics saves a lot of cognitive bandwidth, but to my surprise it has been replaced. I thought I'd feel more 'free', but instead I now feel self-imposed pressure to make this one shot count. I know my runway is limited, so every day that didn't tangibly contribute to bottom-line growth feels wasted. I can rationalize it by reminding myself that I can always get a job and try again later, and that I should be spending most of my time on mid to long-term goals that have delayed effects. But that hardly changes how I _feel_. All in all, I'm really glad I made the jump, and I'm still super excited about what I do now.

> conveniently

For many people it's more convenient to do DNS lookups on nslookup.io than googling the syntax and order of dig arguments, opening a terminal and entering it themselves. Plus, it can be convenient to get an overview of the popular record types, instead of doing 7 dig queries yourself.

> the same info

Nslookup.io provides more info than dig/nslookup CLIs: info about the A/AAAA IPs, logos for hosting providers, parsing DNS records, and more to come ;)

> In any case congratulations for finding a use case!

Thank you!

If you like these kinds of stories, check out indiehackers.com. I took a lot of inspiration from them, and was part of the reason I made the jump.

I'd be surprised if it was caused by adding the DNS record, and not for example you visiting the test site. In any case, sooner or later those attacks will come, so omitting a DNS A record won't cure it.
pul··on I quit my job to make free web tools
I’m not yet making a living and it took me years to get to this point. I think I’ve got a reasonable shot to make a living off this now, though.
