> Maybe this helps: [Announcing new Amazon VPC DHCPv6 setting to adjust IPv6 preferred lease time](https://aws.amazon.com/about-aws/whats-new/2024/03/amazon-vpc-dhcpv6-setting-ipv6-lease-time/)

I think you’re right (I even remember I stumbled upon that page but discarded on the spot given the Nitro reference). The relevant part is

> By default, the **IPv6 preferred lease time is 140 seconds** and DHCP lease renewals for IPv6 address assignments **occur at the halfway mark of 70 seconds**

therefore it makes sense seeing logs around every minute or so (precisely, every 70 seconds).

This is for sure something not clear from AWS console `VPC -> DHCP option sets` where no such default 140s default lease time is reported and cannot be changed at all in the existing DHCP config set (no edit button at all):

but you can set the IPv6 DHCP lease time for a brand new DHCP config set!

Due to this, I think we can consider closed the issue!

thanks again @iwalker @Hedges
