Not sure if this is considered an issue or not but I used to get an IPv6 address that had a lease time of 4 days which is the same length as my IPv4 address. Now the past few days I'm only getting a 60 minute lease time for IPv6. Anyone else seeing that?
Not seeing this on my router.
Are you seeing this on the router or directly plugged into the router? I ask because it could be your own router's DHCPv6 server broadcasting on the LAN.
