No. To do this you would need to use SNMP and as fare as I am
aware no DNS server has SNMP hooks as yet.

You do not put IP addresses into NS records. By default anyone
can transfer a zone, all restrictions about transfers are
controlled by allow-transfer directives either at the zone or
server (options) level.
