Round Robin. It works the same.

It will also use subnet mask priortization. DNS will look at the querying
client's IP address. If there is a subnet match, it will offer the record
that matches the subnet. If there are more than one IP, then subnet mask
priortization and Round Robin kicks in where it will offer all possible
records as a list. For each query coming in, it will rotate the list.

If there is no subnet match, all records are offered and rotated for each
query.

If there is no subnet match, then all records
