I've been searching around trying to find what the all the values mean
when dig returns an SOA record. Specifically I'm looking for the zone
refresh time.

$ dig -t soa google.com
google.com. 86400 IN SOA ns1.google.com.
dns-admin.google.com. 2006102401 7200 1800 1038800 60

Is 2006102401 the serial number? Is 7200 the refresh time? Is 1800
the retry time? Making the last two the expire and minimum times?

Thanks for any clarifications.
