I think we'd better clarify the notion of 'Network Attachment'. My thoughts 
are like below. 

When a node attaches to a network, actually there happen two attachment. 
First the node makes link layer connection, then it sets up IP layer connection. 

IMHO, Network Attachment occurs when an interface has made link-layer 
connection. At this stage, though link-layer connection is estalished, a node 
may or may not have IP layer connection. 

Hence, the node has to detect whether it has IP layer connection or not. And
if not, it has to gather the necessary information to set up a new IP layer 
connection to a new IP subent. Which is generally getting a right RA.  

Hence I think, DNA (Detecting Network Attachment) consists of 
1) get a hint of link layer change
2) check it has IP connection.
3) gather necessary information for new IP configuration, if its current IP 
    connection is severed. 

The above is my basic thought but it needs polishing. Any comments?
