Anyone who's rolled out IPv6 on a large internal network or public facing site, why did you bother? Right now it seems like more work and complexity for exactly

  - IPv6 multicast addressing is a real boon on an internal network; the ability to address entire classes of nodes with one address. For example, in IPv4 how would you implement a quick all-routers heartbeat script? In IPv6, just ping ff02::2. - Multihomed hosts are a cinch ( scope identifiers make it easy ), and inversely so are unihomed hosts with multiple addresses. No messing with virtual interfaces like IPv4 requires, just bung another IPv6 address onto the interface. I have some hosts with > 10 addresses on one interface, each aligned to a particular service. - Link-local addressing just works without any need for messing with DHCP and ARP like IPv4 requires. A new client joins the network, immediately generates a LL address and is addressable, all without external assistance. It's beautiful. - Router Advertising in my experience has proven much more reliable than DHCP, and much faster. There are still some issues with rogue RAs, however.
