Actually, I suspect most servers now do, at least in the context of Internet service provision. I believe BINDv9 + dnscache + CNS (don't know about maradns, powerdns, or posadis but I believe their relative percentage isn't significant) outnumber BINDv4 and BINDv8. Don't know if Microsoft DNS allows you to limit memory consumption, but I don't think it is used in an ISP context that frequently (although I might be wrong).
