Products that do what A better IP Lookup tool I made does
Most other IP lookup tools I've found are mostly just trying to push you to signup for their API, which is fine but less useful if you're just trying to figure out which IP addresses in your log files are from sketchy locations and likely to do bad things to your application. I merged together a bunch of APIs and some of our own honeypot collected data to make something I hope devs and security folks find useful. If you want to try out a "bad" IP, try this one: https://wafris.org/ip-lookup/104.244.72.115

Hey HN, Last weekend I vibe-coded a cool website that lets you do easy DNS record lookups. I know you can just use dig or nslookup, but oftentimes I'm too lazy to remember the syntax, and there are less technical users who need to manage DNS entries but aren't comfortable with the command line. We debug customer DNS issues often at ImprovMX, and we typically link to tools like mxtoolbox.com to point out DNS record issues. But those tools seem quite bloated and from the 2000s. I wanted something super clean & simple, and there were a few features I thought were ergonomically needed but…

We've just launched an opensource golang `ipinfo` cli that lets you quickly and easily get IP address data from the cli. You can lookup geolocation, isp, carrier & vpn status for a single IP (in much the same way you can by `curl ipinfo.io`) but there's a bunch of additional functionality, including: - bulk lookups of IPs - summarize IPs (so get top ASNs, cities etc from a ton of IPs) - grepip subcommand to grep for IPs (v4, v6 and bogon flags available) - map command to map a bunch of IPs And more! See https://github.com/ipinfo/cli for more details and installation…

We recently launched a free tool that shows a summary of the top cities, countries, asns, routes and much of the other context that we (IPinfo) have for any IP addresses you paste into it. Sample results: https://ipinfo.io/summarize-ips/result?id=239e90aa-88b8-4476-84c7-bfd10ed2de3f You can paste any arbitrary text into the tool at https://ipinfo.io/summarize-ips and we'll extract the IPs. It can be useful for getting a quick summary of a set of IPs (eg. click on first google result for "public proxies", copy and paste the results into the tool, and see…

Hi HN, I built a free BGP looking glass and IP/ASN lookup tool. You can paste in an IP (v4 or v6), a domain, or an AS number and get whois, routing info, and the global BGP view. Try: https://god.ad/view/8.8.8.8 https://god.ad/view/2606:4700::1111 https://god.ad/view/AS13335 https://god.ad/view/google.com Can also be added to mobile homescreen as PWA

I'm a network engineer that likes to think about the future of the internet and this is what I've built over many nights and weekends. One reputation graph over IPs, ASNs, domains, and entities, exposed as a JSON API. Try it: curl https://api.tunnelmind.ai/v1/check/1.1.1.1 Every answer is a signed receipt with an attestation tier so you can see what was produced and how your agents can use it. The protocol is opensource. Try it out let me know what you think and yes I am still working on the radar section of the site. Also What would make this useful for you?

This can be used to find phishing domains or domains matching any pattern you want if you select "custom filter." You can also connect over WebSocket at /ws and use any programming language you want. There may be duplicates because some domains are published in multiple logs. I get data from all of the logs currently included with Chrome, a list of which is available here: https://github.com/google/certificate-transparency-community....

Hello! I just made my first web app with Sinatra. It is a REST API that helps people add two-step verification to their websites or apps. I am a complete noob in web development so please criticize me and let me know how shitty this whole thing is. :) http://two-step.herokuapp.com/

I get at least one phishing text message every week, and discovered that reporting malicious domains was a major hassle. You have to first manually do a whois lookup, and since not every registrar includes an abuse contact email in their whois record, you often have to then go to the registrar's website and try to find their abuse reporting section before you can report the domain. I figured something had to exist already for reporting domains directly to their registrars, but I couldn't find anything, so I spun up DomainReporter mostly as a tool to use myself, but also to make the process…
