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?
