Log Sanitizer
Clean up IPs, hostnames, credentials, and other sensitive fields before pasting a log into a ticket, vendor case, or chat.

Subnet and VLSM calculators, base and hex converters, a hash verifier, ACL builder, port matrix, and more. All offline.

DNS Lab
An offline DNS simulator with dig-style queries, a zone database, a visual resolution path, and broken scenarios to troubleshoot.
Routing Lab
Practice longest-prefix matching, routing tables, packet paths across three routers, and BGP best-path selection.
Firewall Rules Lab
An ordered ACL simulator. Move the rules around, send test packets through them, and see which one actually wins. First-match-wins and implicit deny make a lot more sense once you can watch them happen.
Network Fault Lab
Diagnose and fix problems on a simulated network, then practice Cisco IOS, Dell OS10, and Juniper Junos commands on the same console.
vSphere Sandbox
Practice the vSphere Client offline with clusters, hosts, VMs, power operations, and vMotion. Nothing connects to production.
