Ping & DNS V 因设备而异

• 开发者：Ulf Dittmer

(For an explanation of the GPS permission, see below.)

Displays network information and diagnostics: Ping a server, DNS lookup (with geographical lookup of IP addresses), reverse DNS lookup, WHOIS queries, inspecting HTTP response headers, trace routes (also with IP address geo lookup), check whether a range of ports is open.

Recently used servers/IP addresses are remembered for auto-completion.

The results can be copied to the clipboard (via long-click on the output text), sent via email or stored in a file as text or PDF. A history of the results of recent operations is kept (swipe left and right to switch between tabs).

Numerous options (like using an alternative name server, Ping TTL, showing ping times for each traceroute step, Broadcast Ping, using HTTPS, setting the HTTP port number, selection of DNS record types to query, etc.) are available through a long-click on the "Go" button.

Contains no ads.

Please join the Google community "Ping & DNS" where I support this app, especially if you're having problems.

New in 1.10.2: It allows individual tabs to be closed via the close icon in the top left hand corner, and the options menu item now closes ALL output tabs. Also, it automatically hides the soft keyboard while output tabs are displayed.

New in 1.10.1: Fix for the crashing exception when trying to bring up options for menu items that don't have any (Whois and Network Info).

New in 1.10.0: New 'Network Info' menu for showing information about all available network interfaces as well as basic IP information about the currently active connection.

New in 1.9.0: Splits the main screen into tabs, one for the input elements, and one or more
for the results pages. Swipe left/right to switch between them. Previous results are pushed to the right, so a history of operations is available. (Individual pages can also be removed via the options menu.)

WHY THE GPS PERMISSION? First off, GPS is only accessed if the "Show Location" checkbox is set in the Ping Options dialog. This checkbox is turned off by default, so unless you explicitly set it, you don't need to worry about your location ever being tracked. Tracking location is useful for measuring ping times during long-running pings across large areas, like a factory or a university campus. Once a long-running ping with location is done, a Google Earth file (.dmz) is created that shows the ping times along with the geo location of each ping. Most people will never need this option, so you don't have to worry. And even if you do use it, location data is stored on the device, it is not sent or uploaded anywhere (the exception being if you attach the Google Earth file to an outgoing email - in which case you're in charge of where the email is sent to). So all the negative comments you may see in the Play Store are unfounded.
