The mission is simple: to build a better toolbox for developers and sysadmins - cleaner, faster, and free of clutter, ads, and meaningless buzzwords. No nonsense, no BS - just straight-to-the-point tools that solve real problems.
Each individual tool must exceed existing online tools - or at the very least, match the best, with zero compromise on usability, simplicity, or actual value.
On a personal level, it’s about experimenting and having fun. I built this because I love solving problems, writing code, and seeing things work - without dealing with suits, deadlines, or the pressure to squeeze profit out of every click.
The need for this grew out of my day job as a full-stack developer and systems administrator.
I needed a set of fast and reliable tools with advanced options to tweak, clear and understandable results, and no ads or useless information cluttering the interface just to make it look fancy.
I needed simple, to-the-point tools that provide actual valuable information.
At the same time, I needed a pet project to help keep me sane. I love coding and building things - but jumping through all kinds of hoops in the corporate world is a recipe for severe burnout. Been there, done that.
Finally, I decided to do something about it... And here we are :)
My name is Flemming V. Bundgaard, a tech professional from Denmark with a broad range of experience in systems development, systems administration, and support. Over the years, I’ve been involved in building and managing technical systems designed to optimize workflows and simplify complex processes.
In my current roles, I oversee the development and technical operations of several large-scale systems, including platforms for managing digital transactions and integrations with numerous third-party services. My responsibilities cover everything from initial coding to ongoing system maintenance and API integrations, ensuring smooth and reliable functionality.
I have a background in freelance consulting, where I developed custom websites and applications across multiple industries, always with a focus on practicality and simplicity.
I work with technologies such as C#, .NET Framework, JavaScript, MySQL, IIS, Windows Server - to name a few. And I love everything about both SQL and DNS :)
I'm reachable - by mail - at iamrootdottech@gmail.com. Any kind of feedback, is more than welcome!
Please keep in mind, as this is a pet project I work on besides my dayjob, I may need not be able to respond instantly. But I'll get back to you in a couple of days.

The stack behind iamroot.tech is old-school C#, .NET Framework, MySQL, IIS and JavaScript. Nothing particularly fashionable - but it is rock solid and behaves extremely predictably. When it comes to operations, that is pretty much all that matters.
Every tool on the site is developed and maintained by me. Some NuGet packages are in play for the low-level stuff, but the tools themselves are built from scratch and maintained by me.
All parts of the code and infrastructure are built with cost, reliability and resilience in mind. Cheap VPS servers across multiple geographical locations, datacenters and providers, tied together by very simple DNS-based routing - users are directed to the nearest healthy server.
Outages are always to be expected. How you handle them makes all the difference.
It is all very basic and simple - but extremely effective in terms of both cost and uptime.
This has a huge impact on how I design systems. The simpler and more transparent you build, the more predictable things become once in production. It is boring, yes - but very, very effective:
I have a ton of ideas and ambitions for the website. This roadmap is not a definitive list - but it gives you an idea of the direction, the ideas, and the tools I'm working on.

Running these tools takes real resources. Servers, DNS hosting and whatnot... it all adds
up. And while I do everything I can to keep costs down,
even dirt-cheap hosting still costs money.
If you find the tools useful, a donation helps keep everything online, fast,
and completely free of ads. It also opens the door to new tools, new locations,
and better performance for everyone using the site.
To keep it as painless as possible, donations are handled through PayPal.
Thank you in advance.

PS: The least I can offer as a thank-you is an honorable mention, a backlink,
and some SEO love. I will reach out after any donation.
Beside the tools (listed below), a couple of related services are offerede as a part of the iamroot.tech website:
The system allows you to put your lookups, checks, and monitoring tasks on autopilot.
A basic http-based JSON API on several of the tools, allowing for custom development and use of the tools.
Online tool for advanced DNS lookups (nslookup / DIG-style). By default, it performs recursive queries against authoritative name servers - but custom DNS resolvers are supported too. Includes secondary records for a complete overview and provides a full technical log for debugging and insight. 
Check how DNS records are propagated throughout the world. It will start by examining the authoritative name servers and compare the records with the results from over 20 DNS servers worldwide. 
Scan any IP for any open ports. Includes probing functionality on DNS, SMTP, POP3, IMAP and HTTP protocols if open. 
Perform WHOIS and/or RDAP lookups on domains, IP addresses, and ASNs. Will output all available technical info, contact info, etc. 
Test HTTP/HTTPS requests with full control of headers, body, and method. View raw request/response. Great for debugging, monitoring, and setup checks. 
Check any server’s SSL/TLS certificate for validity, expiration, full chain of trust, and protocol support (TLS 1.0–1.3, SSL2/3). Includes PEM details, root store trust (Microsoft, Apple, Android). Supports check of HTTPS, SMTP, IMAP, and POP3. 
Check IP or domain against the most common e-mail blacklists. 
Perform rDNS lookups on IPv4 or IPv6 addresses. Check PTR records to see the hostname behind any IP. 
IP to CIDR calculation tool with subnet info. The reverse, CIDR ranges to IP addresses, is also possible. Last but not least, it includes a tool for refactoring groups of IPs, domain names, and/or other CIDR ranges. 
Online tool for checking the contrast/readability of two colors - and get hints for optimizing the contrast. 
Pick any color - and see info on related colors, contrast colors and different shades. 
Generate strong passwords up to 32 characters. Customize length, casing, numbers, and symbols. Copy or read aloud with phonetic NATO codes. 
Generate lorem ipsum with custom readability levels. Create dummy text that matches your content’s complexity. Output as plain text or HTML. 
Beautiful day/night map of the world, with markup of all major cities including local date and time. 
Search the detailed ASN/BGP database for insights into peers, announced prefixes, upstream/downstream relationships, and IX memberships. Search by ASN, IP, or CIDR block. Includes organizational metadata like name, description, network type, logo, website, and social media links. 
URL encoding/decoding tool to convert special characters to percent-encoded format and back. Great for debugging, query strings, API testing, and safe web development. Based on RFC 3986. 
Online tool for HTMLencode and/or HTMLdecode of any string. 
Online tool for BASE64 encoding af binary-to-text, and BASE64 decoding for text-to-binary.

GeoIP lookup tool. Supports lookup of ip's in bulk - and lookups based on domainnames. Includes ASN/ISP data. Based upon the MaxMind database. 
Ping tool for testing connectivity to a host, measuring response times, jitter, and packet loss. Global ping works like regular ping - but from multiple sources worldwide, simultaneously. Traceroute maps the full path data takes, showing each hop’s response time, ASN, and geo-info to diagnose network issues. 
This tool answers a simple question: Is the service actually reachable? It’s an advanced, multi-protocol UP/DOWN checker - far beyond a basic port test. Supports dozens of test flows, including web, APIs, mail, databases, remote access, and more. It connects, handshakes, waits for a real response, and verifies that the service behaves as a healthy client would expect.
