[Kea-users] Specifying the lifetimes for ipv6 temporary addresses

[Darren Ankney]

Hi,

Are you sure the IA_TA are coming from Kea?
https://kea.readthedocs.io/en/kea-2.6.3/arm/dhcp6-srv.html#supported-dhcpv6-standards

- "Dynamic Host Configuration Protocol for IPv6 (DHCPv6), RFC 8415:
This new DHCPv6 protocol specification obsoletes RFC 3315, RFC 3633,
RFC 3736, RFC 4242, RFC 7083, RFC 7283, and RFC 7550. All features,
with the exception of the RECONFIGURE mechanism and the now-deprecated
temporary addresses (IA_TA) mechanism, are supported."

- "Temporary addresses are not supported. There is no intention to
ever implement this feature, as it is deprecated in RFC 8415."

Thank you,
Darren Ankney
