IPv6Why it is a better protocol than IPv4?
IPv6 Designed for the Internet of todayIPv4 was designed for a private networks in the late 70s
128 bit Addresses!
This a huge number!
No chance to exhaust it
Enough to address each atom of Earth and do 4 more Earth Fred Bovy
Plug and Play
No more configuration on the end nodes.
IPv6 is plug-and-play
Configuration is performed on routers and servers
SaferInternet today is fully opened to hackers who are the Internet Owners. They can get through any firewall and do whatever they want!
If the Network Designers follow the IETF recommendations most end nodes SHOULD run IPSec
IPSec was initially designed for IPv6
No More NAT needed!
Peer-to-Peer which was a key driver for the migration to TCP/IP in the 80s was killed by NAT.
It is not more insecure without NAT if you implement Statefull Firewall at the Edge of your Network and only allow IPSec traffic to get in!
Anyway you will also need to implement Host based firewalls on each system talking to the Internet
