Re:Ask HN: How to Evaluate IP Dataset? on Thursday March 19, 2026 @01:40PM (#47443045)
As some said, don’t trust pricing or marketing claims, run your own benchmark based on your requirements.

Measurement-based probing has been used by major IP intelligence providers for years. Some just market it better than others But it’s not a silver bullet, a lot of IPs (mobile, CGNAT, enterprise) aren’t consistently probeable or yield ambiguous results.

In practice, no single method wins. Hybrid approaches usually perform better.

(For transparency: I work for https://ipregistry.co, worth including in your benchmark if you’re comparing providers.)

Re:ChatGPT knows my IP geolocation on Saturday November 15, 2025 @04:44AM (#45936261)
This is mostly just basic IP geolocation. I work for Ipregistry (ipregistry.co), and this kind of lookup is something we provide: country, region, city, ASN, hosting provider, VPN usage and similar signals. Any service that sees your IP can request that information in a single query.

ChatGPT receives your IP when you connect. The model itself does not know your location, but the system around it can add location context before the model answers. Many products do this because it helps with weather, time zone handling or local recommendations.

Accuracy depends on your network setup. VPNs, mobile networks and corporate proxies can make the location drift quite a bit, but at a general level it is often good enough to shape responses.

The more important part is transparency. Inferring location from an IP is normal, but it should be clear to users when that information is being used.

There exist alternative solutions like ipregistry.co (note I work there).
That's interesting but what sources are you supporting? are you crawling them periodically? at what rate?
IPInfo appears to have good data, but their main advantage is strong marketing. They've effectively built a community of fanboys by publicly sharing techniques and methods that other major providers have been using for years or even decades.
Re:IPinfo's IP Hunt: 2.2M IPs submitted over 3 weeks on Saturday February 10, 2024 @03:02PM (#39329686)
Let's people judge. There is no perfect solutions.

A great IP intelligence solution is also ipregistry.co

Re:IPinfo's IP Hunt: 2.2M IPs submitted over 3 weeks on Saturday February 10, 2024 @01:21PM (#39328788)
You also have ipregistry.co (https://ipregistry.co/).
The idea is great but you will never compete with a solution like Google translate: one simple reason is that Google Translate is highly specialized and optimized. Did you try to compare the processing time?

Running an opensource AI model to perform translation may help and work in some cases but to be honest this has also a lot of limitations. The first being processing time and the second languages support. I am not even considering accuracy.

It has "open" in the name! and an ugly UI :)
Same error here!
Re:Migrating to Cloudflare Email Routing on Wednesday February 09, 2022 @03:53PM (#30278337)
I thought exactly the same the first day Cloudflare announced Email Routing. Email sending is a few Billion with only a few large competitors. I guess that's one of their long-term plan or at least I hope so. They have knowledge, market, and money to provide better-added value than Amazon SES.
Re:Saving on egress switching from AWS to Hetzner on Monday January 24, 2022 @05:59PM (#30065313)
Great article. I wrote about a similar experience 9 months ago while switching from Google Cloud Storage to Scaleway Object Storage:

https://pellegrino.link/2021/05/31/scaleway-object-storage-s...

Similarly, I saved about x100. For sure, the services do not offer the same level of guarantees and speed but depending on my case it was worth a migration.

Looking forward to trying Cloudflare R2 soon!

I was in the same situation about 5 years ago: a lot of experience as a backend engineer and no real experience in frontend. Today, I am quite proud of what I know and built: noticeable.io, especially the dashboard.

My bet was to "learn" about the Web platform and not a specific framework. However, to build a Single Page App, you need a library. At that time, I fell in love with Polymer as a minimal library to create a Single Page App. Nowadays, this is replaced by Lit (lit.dev). The library is minimal and aims to use the Web platform as much as possible. I suggest giving it a look.

Besides, when I say "learn", I mean developing a project or something from scratch. You will most probably end up using TypeScript, Jest, Rollup/Webpack and Lit ;)

Good luck!

Re:Where do you find solutions for a problem? on Thursday June 17, 2021 @04:08AM (#27537243)
quora.com?
That's an interesting comparison but that's a shame to see great services such as IPregistry.co to not appear in your analysis.
