sn = serial number
Unsigned 32 bit value in range 1 to 4294967295 with a maximum increment of 2147483647. In BIND implementations this is defined to be a 10 digit field. This value MUST change when any resource record in the zone file is updated. The convention is to use a date based value to simplify this task - the most popular being yyyymmddss where yyyy = year, mm = month and dd = day ss = a sequence number in case you update it more than once in the day! Using this date format means that the value 2005021002 means the last update was on the 10th Febrary 2005 and it was the third update that day. The date format is just a convention not a requirement so BIND will provide no validation of the field. It is easy to make mistakes and get serial numbers out of sequence. Fix Serial Numbers.
