ShellMonkey, 2 months ago How much simpler can I make this… You have a primary ‘master’ server in the pool. Replica/cache servers periodically ask the master for any updates. Master gives a new update, which is a sinkhole for a marked malicious domain. Replica/cache server now resolves malicious domain to the sinkhole address. This is not a ‘feature’ you have to implement, it’s a basic function of running a redundant DNS system.
