I think the first field contains the URL and the second field contains the port number. I am not sure about the third and fourth fields. I think the fifth field contains the IP address.
I've reviewed http://www.madboa.com/geek/dig/ and https://kb.mediatemple.net/questions/909/Understanding+the+dig+command, and am still unsure what each section represents.
Reference: http://www.zytrax.com/books/dns/ch15/#answer and http://www.zytrax.com/books/dns/ch8/a.html
The first field is the NAME: The domain name being returned
The second field (108 in your example) is the TTL in seconds.
IN is the CLASS. Here, IN stands for Internet.
A is the TYPE. Here, A stands for mapping a domain name to an IPv4 address.
The last field is of course the IP Address.
