Hello, Could you please clarify whether Knot can perform a zone transfer not from the first master listed, but from the one that sent the NOTIFY? The masters are configured in the following order: remote:   - id: master     address: [ "192.168.58.151", "192.168.58.134" ] When a NOTIFY is sent from |192.168.58.134|, the zone transfer is still performed from |192.168.58.151|. Here are the relevant log entries: Apr 25 19:09:25 ubuntu knotd[2065]: info: [chacha.com.] notify, incoming, remote 192.168.58.134@32888 TCP, serial 2006 Apr 25 19:09:25 ubuntu knotd[2065]: info: [chacha.com.] refresh, remote 192.168.58.151@53, remote serial 2006, zone is outdated Apr 25 19:09:25 ubuntu knotd[2065]: info: [chacha.com.] IXFR, incoming, remote 192.168.58.151@53 TCP, receiving AXFR-style IXFR Apr 25 19:09:25 ubuntu knotd[2065]: info: [chacha.com.] AXFR, incoming, remote 192.168.58.151@53 TCP, started Thank you for your product and for your help! *Best regards,* *A.A.
