We are in the process of implementing the following:
After any change to name server details for a domain name a notification message will be sent to the email address in the soa record for the master name server.
What does "master name server" mean?
All you have is a list of _authoritative_ nameservers. You have no way of telling whether individual nameservers are masters or slaves.
Do you mean the first listed authoritative server?

Joe, In an SOA record for a domain, the 'primary' or 'master' nameserver is listed, next to the admin email address for the domain. e.g. :
$ host -t soa waikato.ac.nz. waikato.ac.nz start of authority nscache.waikato.ac.nz soa.waikato.ac.nz( 2000051901 ;serial (version) 72060 ;refresh period 3600 ;retry refresh this often 2592000 ;expiration period 86400 ;minimum TTL )
where 'nscache.waikato.ac.nz' is the 'master' server for our domain,
and soa(a)waikato.ac.nz is the contact email address.
I'm not sure if the primary server field is just informational or
actually used by the nameserver, but it used to be checked by the
old registry system, and also indicated to ns1.waikato.ac.nz as to
where to zone-transfer a zone file from.
If someone want to setup a shadow primary, and have only the secondaries
listed, I guess they have to list one of their secondary servers in the
SOA record instead, and not let the registry know of their primary server.
Hope this helps,
Geoff.
