Network Port Database


This application contains a database of the network Ports as they are assigned by IANA.

With this application you can see which application is registered to use a port or, vice versa.

Before you can use this application, you will need to download a copy of the OUI database. To do that press "Menu->Update DB". I refresh and  upload this database weekly.

In the next few days I will release a windows application which can be  used to create that database so you can update it manually.

For more information about port numbers see here:

No ads.

  • Before you use this  application, you need to download a copy of the Port Database. To do  that, Press Menu->Update DB. Keep in mind it is about 0.5MB.
  • To perform a wildcard search, use the percentage sign (%). So typing "HT%" will search for all items which start with "HT".
  • The search is case insensitive.



  • v0.1.0 First public release
  • v0.1.1 UI Fixes, fixed DB sanitisation bug, added better error messages.
  • v0.1.2 More UI fixes.
  • v0.1.3 Added "Hide" button.

  • ACCESS_NETWORK_STATE: Used to check if the device is on-line and using which interface.

To download the application you'll need to go to the Android Market and search for "Network Port Database".
