Take the 2-minute tour ×  If I have a master DNS that is not
bind - can bind still slave to it? (ie does it use the DNS
protocol or something else?).  Kind of related - but do people
still do this or do they use some other form of data replication
to keep DNS records in sync to the slaves (ie file/database
copying)? I would like to have the slaves refreshed as fast as
possible so I am thinking normal slaving with is expiry/poll
based might not be optimal?  share|improve this question add
comment  2 Answers  up vote 2 down vote accepted  You're looking
for DNS zone transfers. This mechaism copies DNS zones between
DNS servers as either a complete transfer, or an incremental
transfer of updated records (to save bandwidth and reduce update
latency). DNS NOTIFY allows the master server to inform
secondaries that updates are available. With NOTIFY, polling
isn't necessary.  Virtually every DNS server implementation
supports zone transfers. BIND will happily act as as secondary
DNS server for any primary DNS server
