Can I specify an AP to go online from a specific AC if it obtain its IP addresses from the same network segment?

Yes. You can configure theloopback addresses of multiple ACs in the DHCP address pool and specify an ACto which the AP's MAC address is bound. Enable AP compliance check on the AC.

Ruijie>enable//Entering theprivileged EXEC mode.

Ruijie#configureterminal//Entering the global configuration mode.

Ruijie(config)#ac-controller

Ruijie(config-ac)#bind-ap-mac//Enablingthe AP MAC address binding function.
Bind AP MAC function is on.//Indicating that the AP MAC address bindingfunction is enabled.

Ruijie(config-ac)#exit
Ruijie(config)#ap-config JXL-01//The AP name in the ap-config command is JXL-01, which can be set as required. Chinesecharacters are not recommended.

You are going to configAP(JXL-01), which is not on line now.//Normal prompt
Ruijie(config-ap)#ap-mac 1414.4b13.c248//Binding the MAC address of the AP.
Ruijie(config-ap)#end

Ruijie#write //Saving theconfiguration.

After multiple loopback addressesare specified, the AP will send requests to these addresses. However, the APcan go online through only the AC to which the AP's MAC address is bound.
