IPv6 Flashcards
1
Q
IPv6
How do VPCs handle IPv6 routing with IPv4 addresses?
A
They don’t. All routing is separate for IPv4 and IPv6.
2
Q
IPv6
How do you dual-stack a NAT Gateway to handle IPv4 and IPv6?
A
Can’t, and it isn’t needed. NATGW tech exists to conserve or deal with IPv4 exhaustion.
3
Q

So how do you “hide” IPv6 subnets in a VPC from all being available on the public Internet?
A
Egress-only Internet Gateway: all IPv6 goes out, nothing outside can reach in.
4
Q
IPv6
How do you handle bidirectional IPv4 traffic in a VPC with only one-way IPv6?

IGW for only IPv4, Egress-only IGW for IPv6 traffic.
