For example, you have 2002:0C9B:A665:0001:0000:0000:0C9B:A665 as your 6to4 IPv6 address. Your IPv4 address will be 0C9B:A665 which you can view as 0C.9B.A6.65 then you can convert it to decimal to get 12.155.166.101 for your dotted-decimal IPv4 address notation.
will yeah in the end 0C.9B.A6.65 it’s an ipv4 which means you embeds Ipv6 to ipv4. So the answer is C embeds an IPv4 address within an IPv6 address 4to6.
Tunneling is a feature that is used to transport packets from one type of network over a network of a different type. The most common type of tunneling is 6to4 tunneling. This type of tunneling allows for IPv6 packets to be transported over an IPv4 network through encapsulation. 6to4 tunneling was created to support both IP types during the transition from IPv4 to IPv6. A less common type of tunneling is 4to6 tunneling. This type of tunneling allows for IPv4 packets to be transported over an IPv6 network .
So ans is C
C is the right answer, this is from cisco https://www.cisco.com/c/en/us/support/docs/smb/routers/cisco-rv-series-small-business-routers/smb3808-tunneling-configuration-on-rv215w.html
Agree with David:
6to4 embeds an IPv6 in an IPv4 address
https://en.wikipedia.org/wiki/6to4
The question is for the situation of IPv4 embedded into IPv6, so that is logically 4to6 , answer C
Answer is C not B
answer in exam is 6to4.
Really?
I have the same problem. The correct answer is 6to4, but it means IPv6 embedded in IPv4, and not vice versa! So the question is wrong then?
