AutoRegistration and 2 interfaces

[william-cl]

zabbix server 6.4
proxy server 6.4
with agent 4.2.5 and 5.0.23 and 6.4

If we bring a new host online it autoregisters itself to the proxy server and we see a new host in zabbix with 1 interface using IP
shortly afterwards (5-30 minutes) we see a second interface added using DNS

our zabbix agent conf
PidFile=/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
Server=zabbix server ip
ServerActive=zabbix server ip
HostnameItem=system.hostname
HostMetadataItem=system.uname
Include=/etc/zabbix/zabbix_agentd.d/*.conf

Is this a feature? or am I missing something? How do i prevent this?

thank you in advance.

No one has seen this issue?

I have not seen this before...

Do you have multiple autoreg rules/discoveries? Or you have some external actions somewhere?

By default agent registers with IP as primary contact method. To force registering with DNS as primary, then you need to use HostInterfaceItem parameter... But you don't have that...

Do you have multiple autoreg rules/discoveries? one for each OS (linux or windows)
have some external actions somewhere? nope

william-cl were you able to get a fix for this issue? I have the same issue.
i do not even have HostnameItem or HostMetadataItem defined. I see the host first registers with Ip and then re-registers again with to add a new interface with DNS and it doesnt stop there. The host keeps re-regstering back again and again. Not sure what is going on.
