Someone please correct me if I give misleading information. I don't believe I am, but I've been wrong before :D There's a good section about this in the ARM, such as BIND 9.7 ARM section 4.3 - Incremental Zone Transfers (IXFR). Basically, a BIND 9 slave will normally ask for IXFR unless told not to (request-ixfr). A BIND 9 master can't always provide IXFR though - if it can't it will provide AXFR instead. To be able to provide IXFR it needs to have some idea of the changes being made, so it can give a meaningful reply when asked to provide "all changes since serial number X", so you'll normally see IXFR being possible for dynamically updated zones (and a couple of other cases, check the ARM).
