taking a shot here, am also new to TCP/IP so still learning...
TCP/IP is connection oriented, to establish a connection between 2 hosts, your PC sends a SYN (synchronize) bit to the other computer. Your PC then waits to receive an ACK bit, or acknowledgement bit from the opposite end. Finally, your PC sends another bit to tell the other computer which sequence number to begin with. When all of this hand shaking is complete, data begins to flow.
From O'Reilly, TCP Network Administration
"TCP views the data it sends as a continuous stream of bytes, not as independent packets. Therefore, TCP takes care to maintain the sequence in whihc bytes are sent and received. The Sequence Number and Acknowledgement Numbers in teh TCP segment header keep track of the bytes"

Your computer is attempting to open a TCP connection with another computer, looks like something related to the name server (perhaps a zone transfer from a zone that is not responding to your request?).
One way to resolve this is to use lsof to see which processes are attempting to open the connection. When you find out which processes on your end are attempting to open the connection, you can then determine the appropriate next step.
