Android :: Domain Name Won't Resolve To An IP Address

I am working on a program that will connect to a time server (time- a.nist.gov), retrieve the timestamp, and place it in a text field.

However, when I create the socket, I get an UnknownHost Exception for time-a.nist.gov

1. put the <uses-permission android:name="android.permission.INTERNET" /> tag right before the </ manifest> tag. I did this, and the change is still there.

2. use the static InetAddress.getByName() function to convert to an IP address (this still throws the same exception)

When I pass the IP address (129.6.15.28) to the socket constructor, the program works fine. It only breaks when I use the actual domain name.

I have written this program in Java and it works perfectly fine.
