Free online network tools

How this site works

The tools at CentralOps.net are free for everyday, interactive use—no login required. Simply pick a tool on the left and use it.

As an anonymous user, you get 50 free service units every 24 hours. Whenever you use one of the tools, its cost in service units is deducted from your balance. If your balance runs out, you will get more free units at the end of the 24-hour period. The free units are more than enough for 99% of our users, but if you want extended or automated use of our tools, paid accounts are available.
