Summary: As currently implemented IPv6 networksmight actually be less secure than IPv4. It is true thatIPv6 was designed with more security in mind. Unfortunatelymost of the good stuff like builtin IPSec was left out as optionalwhich means that today's IPv6 connection are not betterprotected than IPv4.

Correspondingly, is IPv6 secure?

IPsec makes IPv6 more secure thanIPv4 Internet Protocol Security (IPsec) was designedto provide network layer security (authentication andencryption). It was included as a mandatory feature in theIPv6 standards. Many believed, and some still believe, thatthis gives IPv6 an advantage over IPv4.

Subsequently, question is, should IPv6 be enabled? If you don't have an IPv6-enabled routeryet, you don't need to buy a new one just to get it. An ISP WithIPv6 Enabled: Your Internet service provider must also haveIPv6 set up on their end. Even if you have modern softwareand hardware on your end, your ISP has to provide an IPv6connection for you to use it.
