This a very heterogeneous business, aka "we do whatever the customer pays for".
One customer has one or two whole /8 blocks of public IPs that they use even for internal systems in our data centers. Others are IPv6 on the inside and IPv4 public facing. Some are big layer 2 setups (which we internally route through IPv6).
