Hello BIND experts,
I'm not a DNS expert. Suppose i have two BIND servers. Both have the entries below:
vpn.pepsi.com. in ns adns-LA.pepsi.com.
vpn.pepsi.com. in ns adns-NY.pepsi.com.
adns-LA.pepsi.com. in a 22.214.171.124
adns-NY.pepsi.com. in a 126.96.36.199
Question#1: Are lookups for vpn.pepsi.com being round-robined or are both A records being returned to the client?
Question #2: If lookups are being round-robined, supposed adns-la.pepsi.com (188.8.131.52) goes down. Wouldn't BIND still try to answer with that record? I assume yes since it doesnt have a way to know that adns-la.pepsi.com is down.
