Linux try to resolve domain adding its domain ..

Feb 14 14:49:26 ns1 named[22796]: client 127.0.0.1#32798: view
internal-in: query: 328e9u238du32.com IN A +
Feb 14 14:49:26 ns1 named[22796]: client 127.0.0.1#32798: view
internal-in: query: 328e9u238du32.com.test.net IN A +

But /etc/resolv.conf have only "nameserver 127.0.0.1".

Is it normal?
