reverse-dns

I'm creating a custom Android SyncAdapter and hit a snag following the SDK example "SampleSyncAdapter". - I'm creating my equivalent of the xml/syncadapter.xml . Here's the parts I'm confused about: android:contentAuthority="com.android.contacts" android:accountType="com.example.android.samplesync" The documentation of AbstractThreadedSyncAdapter states: The android:contentAuthority and android:accountType attributes indicate which content authority and for which account types this sync adapter serves.

I am looking to do a large number of reverse DNS lookups in a small amount of time. I currently have implemented an asynchronous lookup using socket.gethostbyaddr and concurrent.futures thread pool, but am still not seeing the desired performance. For example, the script took about 22 minutes to complete on 2500 IP addresses. I was wondering if there is any quicker way to do this without resorting to something like adns-python. I found this http://blog.schmichael.com/2007/09/18/a-lesson-on-python-dns-and-threads/ which provided some additional background. Code Snippet: ips = [...] with

I am trying open a site hosted on my localhost using machine name in an android browser. When I type in machine name on a desktop browser , it gets resolved, but in an android device I get webpage not available. Server has been configured to handle DNS correctly and we do not see any errors.Please help. Thank you There's two things at play here... 1: How is your machine name getting resolved? There are several mechanisms for this. Windows machines use a combination of NetBIOS/WINS/ActiveDirectory to discover other machines on the local network. (Linux/Mac machines can access this data SAMBA,

I have a DNS script which allow users to resolve DNS names by typing website names on a Windows command prompt. I have looked through several guides on the DNS resolve but my script can't still seem to resolve the names (www.google.com) or (google.com) to IP address. The script outputs an error of Traceback (most recent call last): File "C:\python\main_menu.py", line 37, in ? execfile('C:\python\showdns.py') File "C:\python\showdns.py", line 3, in ? x = input ("\nPlease enter a domain name that you wish to translate: ") File "<string>", line 0, in ?
