VerifiedNetwork Penetration Testing Methodology – External

Jack, a network engineer, is implementing IPv6 for a client. He deployed IPv6 on IPv4 networks by using a mechanism in which a node can select either IPv6 or IPv4 based on the DNS value. This simplifies the operation of network resources.

What type of technique did Jack use?

Explanation

Dual-stack networking supports IPv4 and IPv6 simultaneously on the same hosts and network infrastructure. DNS address records can provide IPv6 or IPv4 addresses, enabling nodes to use the applicable IP version.
