Valid Lifetime
Defines the DHCPv6 lease time duration in minutes between 1
and 71582788. A DHCPv6 user’s PC gets an IPv6 address
with a lease time. When the lease time expires, the PC must
connect to the DHCPv6 server and be issued a new, unused
IPv6 address.
Note: The default DHCPv6 lease time is 3600. For optimum
performance, it should be changes to 86400 seconds (24
hours). This helps resolve connectivity issues with some MAC
and Windows 7 devices that turn off the network interface
when they go into standby mode. This results in slow Web
browsing until the device gets a new IPv6 address via
DHCPv6.
