[CentOS] NIC naming conventions and vmware

I have a couple of CentOS 7 machines running in a vmware environment. On 
all the older ones I've deployed, the NIC is named ens160, but on all of 
the new ones, it is named ens192. I can't find any difference in the 
hardware that would account for this.

Any suggestions on what I can do to figure out why some are named ens160 
and some ens192?

Thanks.
