An observation in nsupdate:
Suppose we have two A records as ,
*addforixfr.bind9712.com. 3456 IN A 10.32.21.30*
*addforixfr.bind9712.com. 3456 IN A 10.32.21.20*
When we update TTL value as below for one of the records , the TTL value
changes for both the records.
*update add addforixfr. bind9712.com 8564 A 10.32.21.30*
