VLANlab started as a simple idea - engineers should not need twenty browser tabs open just to do their job. Every time you check a subnet, look up a DNS record, test a port, inspect an SSL certificate or verify email security, you end up on a different site with different ads, different interfaces, and varying levels of trustworthiness. We built VLANlab to fix that.
VLANlab has been six years in the making. It started as a personal frustration and grew into something we are proud to share. It is not a startup, not a funded product, not a corporate tool. It is a passion project built by someone who got tired of switching between twenty bookmarks to do their job.
What we are
VLANlab is the fastest Internet toolkit for IT professionals. Sysadmins, DevOps engineers, developers, and security researchers use VLANlab as their single bookmark for the tools they reach for every day. We cover networking, DNS, security, email, and developer utilities - and we are adding more constantly.
What we believe
Free forever
Every tool on VLANlab is free to use with no freemium limits, no paywalls, and no trials.
No account required
You will never be asked to create an account, verify an email, or log in - open the tool, use it, close it.
No ads, no tracking
We do not run advertising, fingerprint browsers, or sell data because we do not collect it.
Fast and honest
Results come from your browser or our edge servers, and we tell you exactly where they come from and what their limitations are.
The stack
VLANlab runs on globally distributed edge infrastructure. Tools that need server-side execution run on servers close to you around the world - no central origin to go down, sub-30ms response times from most locations, and no infrastructure to babysit. Every result URL is shareable and bookmarkable.
