Meaning of the five fields of the ANSWER SECTION in dig query

dig, dns

Solution

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.

Problem

Here is the ANSWER SECTION when I run `dig www.google.com`: ``` ;; ANSWER SECTION: www.google.com. 108 IN A 74.125.239.115 www.google.com. 108 IN A 74.125.239.114 www.google.com. 108 IN A 74.125.239.116 www.google.com. 108 IN A 74.125.239.113 www.google.com. 108 IN A 74.125.239.112 ``` 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.
