Overview

Simple DHCP Query is a free Android-app for reading out the information received from a DHCP server for the current WLAN connection, e.g. IP address of gateway, DNS-servers, own IP address & network mask. This information can be saved by the app for later reference.

Once a DHCP record is received the app can be used to open the homepage of the current WLAN's gateway server; this page is very often the login page you have to visit before you can use WLAN in a restaurant or hotel.

Further screenshots can be found on this page; there is also a Prezi Presentation which visualizes the navigation between the screens of the app.

Minimum version of Android needed by the app is 2.2.x (Froyo, API-Level 8).

Usecases

• Saving the DHCP record for a WLAN whose DHCP server is not always working. With the DHCP record it is possible to use the WLAN even when the DHCP server is currently down.
• Checking/Debugging configuration of a WLAN.

Features

• App can save an unlimited number of DHCP records (the number of records is only limited by the amount of memory available on the device).
• When saving a record the user can define a title for the record, e.g. "WLAN at Hotel in NY" or "WLAN at Mike's appartment". Also the date & time together with the current time-zone is saved.
• Share single or all records via e-mail oder clipboard. Depending on the device the option to share via e-mail may also include sharing via other apps like note-taking apps or messaging app.
• The app contains a help page which can be displayed without being connected to the internet.

Permissions required by the app

• The app does NOT display advertisement or offer In-App purchases.
• The app needs to query if the Android device is currently connected to the internet and if WLAN is enabled on the device.
• The app can itself not connect to the internet, so it cannot upload DHCP records to a server in the background.

Limitations

The following limitations of the current version are known so far:

• English and German are the only languages supported by app so far. When your device is set to another language then the app will work, but English as default language will be used.
• No special layout for landscape orientation (the app can be used in this orientation, but will use the same layout for its user interface as in portrait orientation).

If you think that you found another limitation/bug, then you can inform the developer of this app using the e-mail address stated on the contact information page.
