Is IPv6 a security risk?

Failure to secure the IPv6 systems is like allowing a huge back-door to exist.” * Security device bypass via unfiltered IPv6 and tunneled traffic. Only a lack of knowledge is considered a bigger risk than the security products themselves.

What is the benefit of IPv6?

More Efficient Routing IPv6 reduces the size of routing tables and makes routing more efficient and hierarchical. IPv6 allows ISPs to aggregate the prefixes of their customers’ networks into a single prefix and announce this one prefix to the IPv6 Internet.

What happened IPv5?

The reason is that the IPv5 doesn’t exist. It never made it to become one of the IP protocols. It was planned as a streaming protocol, and it got to its second version ST2. Its packets had the IP version 5 ID but eventually died as a draft.
