In some ways. Given the unbelievably huge address space, target scanning isn't feasible. Also, IPv6 uses "privacy addresses" in which the address used for outgoing connections changes daily. Incoming connections, such as for servers, remain constant. There are other enhancements that reduced the risk of attacks. For example, with ICMPv6, it's actually possible to limit a message to a single hop, blocking any that come from further out. This blocks a lot of attacks. However, the main benefit of IPv6 is the huge number of addresses available. On Cogeco, you'll get an address block with a minimum of 18.4 billion, billion addresses, all to yourself. On Rogers, I get 256x that. This means I can have blocks for VLANs, subnets and more. Each device capable of IPv6 gets its own public address, compared to using NAT to share a single address on IPv4.

I haven't lost my mind. It's around here...somewhere...
