Secondary DNS / AXFR¶
Often called slave servers (but we don't like that term)
You can setup HexDNS to clone a zone from a primary server and server that as a secondary zone.
Make sure to add our IPs to the ACL on the primary server and through any firewalls:
2001:678:fc8:2::8/12545.129.95.0/24
Tip
If your servers support IPv6 we won't make any attempt to connect over IPv4. You'll therefore only need to allow the small /125 IPv6 range through your ACL.
