Episode notes
Tommy's IPv6 Adoption Journey
- Tommy Jensen shares his journey with IPv6, starting six years ago focusing on encrypted DNS and later embracing IPv6 as the future. - Initially, customers laughed at the idea of IPv6-only, but today it's a common and serious discussion.
IPv6 Mandatory in Windows Today
- Windows requires IPv6 enabled and no longer supports turning it off for supported configurations. - IPv4 remains on by default, but ideally one could dream of IPv6 being the default sole protocol someday.
CLAT is Key to IPv6 Mostly
- Deploy CLAT support across general network interfaces to enable IPv6 mostly environments. - This enables multi-platform devices to interoperate seamlessly using IPv4 within an IPv6 network, easing migration.
