"Blank Name - A record that has nothing in the name slot gets used for all requests made to the base/naked form of the domain."
No, a blank name uses whatever name was used on the previous record. Near the top of the zone file, that name is usually the domain name because of the SOA record. But later on, it won't be.
- grhmc 12y agoSeems implementation specific. BIND does this you're right, but many services don't follow the rule as closely.
