Enable NOTIFY to the zone transfer agents
For best results, use DNS NOTIFY on your primary name servers. This notifies Edge DNS when your zone changes and initiates a zone transfer. Edge DNS accepts DNS NOTIFY by default.
If you would like to use NOTIFY requests, you must configure your primaries to send these requests to all zone transfer agents (ZTAs). As long as at least one ZTA accepts the NOTIFY, Edge DNS has your current zone data. To learn how to subscribe to a list of ZTAs, see Restrict zone transfers to the zone transfer agents.
If you do not use NOTIFY requests, the ZTAs check with your primary name server at the refresh interval listed in your start of authority (SOA) record.
