[CentOS] IP aliases for services (including dhcpd)?

I'd like to consolidate the services from several old servers onto 2 CentOS7 VMs that are currently running dhcpd in a balanced/failover configuration. It will simplify things to add the IPs from the old servers as aliases, at least temporarily so everything will continue to connect without changes.

However, after adding the first one, I see in the logs that DHCPD is sending its DHCPACKs alternating between ens192 and ens192:0 every other time, but oddly it is always using the non-alias IP as the source every time according to tcpdump -n. Is this configuration likely to confuse anything?
